Description

Technical Field

[0001] This invention relates to the field of tire technology, and more specifically, to a tire. Background Technology

[0002] Currently, with the rise of outdoor adventure culture and the popularization of new energy off-road vehicles, mud-tread tires (MT tires) have received widespread attention as a core load-bearing component for vehicles in extreme road conditions such as deserts, mud, and gravel, and the market has also placed higher demands on MT tires.

[0003] In existing technologies, to ensure the reliability of MT tires on muddy roads, manufacturers typically employ larger tread groove designs to enhance their mud-shedding performance. Simultaneously, drivers use lower tire pressure on MT tires to increase their contact patch, improving their ability to sink into mud and sand, and further enhancing traction.

[0004] However, while the traditional design of enlarging the tread grooves of MT tires is beneficial for mud removal, it weakens the strength of individual tread blocks and the overall circumferential rigidity of the MT tire. At the same time, while lowering tire pressure increases the contact patch of the MT tire, it further reduces the overall rigidity of the tire, causing stress concentration and tearing in the tread blocks, thus reducing the durability of the MT tire. Summary of the Invention

[0005] The main objective of this invention is to provide a tire that solves the problem of low overall rigidity in existing MT tires while achieving mud removal performance.

The first angle A1 and the second angle A2 satisfy: 55°≤A1≤60°, 20°≤A2≤25°. Three adjacent connected longitudinal grooves include a first longitudinal groove, a second longitudinal groove, and a third longitudinal groove connected in sequence. The end of the first longitudinal groove away from the second longitudinal groove is connected to the first flow guide groove, and the end of the third longitudinal groove away from the second longitudinal groove is connected to the second flow guide groove. In the direction from the first flow guide groove to the second flow guide groove, the width of the first longitudinal groove gradually increases, and the width of the third longitudinal groove gradually decreases. The widths of both the first and third longitudinal grooves are smaller than the width of the second longitudinal groove.

[0009] Furthermore, the first longitudinal ditch includes a first sub-longitudinal ditch and a second sub-longitudinal ditch that are interconnected.

The extension direction of the first sub-longitudinal ditch is set at a third angle A3 with respect to the centerline X, and the extension direction of the second sub-longitudinal ditch is set at a fourth angle A4 with respect to the centerline X. The third angle A3 and the fourth angle A4 satisfy: 70°≤A3≤75°, 38°≤A4≤43°; and / or, the extension direction of the second longitudinal ditch is set at a fifth angle A5 with respect to the centerline X.

[0011] Furthermore, the pattern structure also includes: a short knife groove, disposed on at least one pattern unit, one end of the short knife groove communicating with a guide groove, and the other end of the short knife groove being spaced apart from a connecting transverse groove; and / or, a connecting knife groove, disposed on at least one intermediate pattern block, the connecting knife groove including a first sub-knife groove and a second sub-knife groove communicating with each other, the ends of the first sub-knife groove and the second sub-knife groove away from each other respectively communicating with two adjacent connecting transverse grooves; wherein the first sub-knife groove and the second sub-knife groove are arranged at an included angle.

[0012] Furthermore, the tread pattern also includes: reinforcing protrusions, provided on the bottom wall of the connecting transverse grooves, with at least a portion of the reinforcing protrusions located at the tire shoulder; wherein the width W2 of the reinforcing protrusions satisfies: 2mm≤W2≤4mm; and / or, the height H1 of the reinforcing protrusions satisfies: 1mm≤H1≤4mm.

[0013] Furthermore, the tread pattern has a contact surface with the driving surface. Along the width direction of the tire, the contact surface has two contact edges, and there is a width T between the two contact edges. The shoulder tread block has an edge close to the tire shoulder. Along the circumference of the tire, one of the two adjacent edges is located at the tire shoulder, and the other of the two adjacent edges is spaced apart from the tire shoulder. Along the width direction of the tire, there is a distance S1 between the two adjacent edges, and the distance S1 and the width T satisfy: 0.025T≤S1≤0.05T.

[0014] Furthermore, the tire also has two sidewalls, each connected to one end of the tread. Each sidewall has a first tread pattern protruding from it. The first tread pattern includes: at least two first guide treads, one end of which is connected to a shoulder tread block, and the other end of which is spaced apart from the end of the sidewall away from the tread. The at least two first guide treads are arranged opposite each other to form a guide recess. A second guide tread is disposed within the guide recess. The second guide tread includes at least two interconnected guide segments, the ends of which are connected to two adjacent shoulder tread blocks. The at least two guide segments are arranged at an angle to form a pointed tip away from the tread. The first guide tread has a short recess, one end of which extends... The guide recess is spaced apart from the other end of the short recess and the side of the first guide flower. Along the direction from the second guide flower to the first guide flower, the groove width of the guide recess gradually decreases. The two side walls of the guide recess are set at an eighth included angle A8, which satisfies: 50°≤A8≤65°; and / or, the guide section has a first inclined surface and a second inclined surface that are connected to each other. The first inclined surface is located on the side of the second inclined surface away from the tread. The first inclined surface and the tread side are set at a ninth included angle A9, and the second inclined surface and the tread side are set at a tenth included angle A10. The ninth included angle A9 and the tenth included angle A10 satisfy: 120°≤A9≤140°, 60°≤A10≤90°; and / or, the maximum height H2 of the guide section satisfies: 5mm≤H2≤10mm.

[0015] Furthermore, there are multiple first lateral tread structures, which are spaced apart along the circumference of the tire. A second lateral tread structure protruding from the tire sidewall is also provided, with the second lateral tread structure located between two adjacent first lateral tread structures. In a direction perpendicular to the tire sidewall, the second lateral tread structure includes a first lateral tread portion and a second lateral tread portion connected in sequence. The projection of the second lateral tread portion onto the first lateral tread portion is located within the first lateral tread portion, so that there is a stepped surface between the first lateral tread portion and the second lateral tread portion.

[0016] According to the technical solution of this invention, the tire tread is provided with a tread structure. Multiple connecting transverse grooves of the tread structure are spaced apart along the circumference of the tire to divide the tread into multiple tread units. Connecting longitudinal grooves are provided on at least one tread unit, and both ends of the connecting longitudinal groove are connected to two adjacent connecting transverse grooves. A flow-guiding groove is provided on at least one tread unit, with one end of the flow-guiding groove connected to a connecting longitudinal groove through one of the two adjacent connecting transverse grooves, and the other end of the flow-guiding groove spaced apart from the other of the two adjacent connecting transverse grooves. The flow-guiding groove includes a first flow-guiding groove and a second flow-guiding groove provided on the bottom wall of the first flow-guiding groove. Along the direction from the connecting longitudinal groove to the flow-guiding groove, the width of both the first and second flow-guiding grooves gradually decreases. This arrangement of multiple interconnected transverse grooves serves two main purposes: firstly, it effectively drains water, mud, and gravel from between the tire tread and the ground, ensuring excellent mud and water drainage and self-cleaning performance; secondly, it allows the tire tread blocks to better embed themselves in muddy ground, increasing friction between the tire and the ground, thus ensuring tire grip, preventing tire slippage, maintaining traction, and guaranteeing driving stability and safety. Simultaneously, the interconnected longitudinal grooves, combined with the interconnected transverse grooves, form mud drainage channels, expanding the drainage path for water and mud and further enhancing mud and water drainage performance. Furthermore, the guide grooves, connected to the longitudinal and transverse grooves, create efficient flow channels, facilitating the smooth ejection of mud and water and improving mud and water drainage performance. Moreover, compared to larger tread grooves, the guide grooves, located on the tread unit, ensure the rigidity of the tread unit and the overall rigidity of the tire, thereby solving the problem of low overall rigidity in existing MT tires while achieving excellent mud drainage performance. Meanwhile, the way the second guide channel is set on the bottom wall of the first guide channel creates a certain step height between the second guide channel and the first guide channel. This not only allows the guide channel to further guide the discharge of mud and water, avoiding the accumulation of mud and water on the tire surface and improving the tire's mud and water discharge performance, but also disperses the stress concentration phenomenon of the tread unit, reduces the risk of tread block cracking and falling off, and improves the tire's durability.

[0046] To address the issue of low overall rigidity in existing MT tires while achieving mud removal performance, this application provides a tire.

[0047] like Figures 1 to 14As shown, the tire tread 1 has a tread structure, which includes multiple connecting transverse grooves 10, connecting longitudinal grooves 30, and guide grooves 40. The multiple connecting transverse grooves 10 are spaced apart along the circumference of the tire to divide the tread 1 into multiple tread units 20. Connecting longitudinal grooves 30 are provided on at least one tread unit 20, and both ends of the connecting longitudinal grooves 30 are connected to two adjacent connecting transverse grooves 10. Guide grooves 40 are provided on at least one tread unit 20, with one end of the guide groove 40 connected to the connecting longitudinal groove 30 through one of the two adjacent connecting transverse grooves 10, and the other end of the guide groove 40 spaced apart from the other of the two adjacent connecting transverse grooves 10. The guide groove 40 includes a first guide groove 401 and a second guide groove 402 provided on the bottom wall of the first guide groove 401. Along the direction from the connecting longitudinal groove 30 to the guide groove 40, the width of both the first guide groove 401 and the second guide groove 402 gradually decreases.

[0048] Applying the technical solution of this embodiment, the tire tread 1 is provided with a tread structure. Multiple connecting transverse grooves 10 of the tread structure are spaced apart along the circumference of the tire to divide the tread 1 into multiple tread units 20. Connecting longitudinal grooves 30 are provided on at least one tread unit 20, and both ends of the connecting longitudinal groove 30 are connected to two adjacent connecting transverse grooves 10, respectively. A flow-guiding groove 40 is provided on at least one tread unit 20. One end of the flow-guiding groove 40 is connected to the connecting longitudinal groove 30 through one of the two adjacent connecting transverse grooves 10, and the other end of the flow-guiding groove 40 is spaced apart from the other of the two adjacent connecting transverse grooves 10. The flow-guiding groove 40 includes a first flow-guiding groove 401 and a second flow-guiding groove 402 provided on the bottom wall of the first flow-guiding groove 401. Along the direction from the connecting longitudinal groove 30 to the flow-guiding groove 40, the width of both the first flow-guiding groove 401 and the second flow-guiding groove 402 gradually decreases. In this way, the arrangement of multiple connecting transverse grooves 10 serves two purposes: firstly, it allows water, mud, and gravel to drain from between the tire tread 1 and the ground, ensuring the tire's mud-draining and self-cleaning performance; secondly, it allows the tire tread blocks to better embed into the muddy ground, increasing the friction between the tire and the ground, thereby ensuring tire grip, preventing tire slippage, and guaranteeing tire traction, driving stability, and safety. Simultaneously, the arrangement of connecting longitudinal grooves 30, combined with the connecting transverse grooves 10, forms a mud-draining channel, expanding the drainage path of accumulated water and mud and further improving the tire's mud-draining performance. Meanwhile, the arrangement of the guide groove 40 serves two purposes: firstly, it connects with the longitudinal groove 30 and the transverse groove 10, forming an efficient guide channel 3, which facilitates the smooth discharge of mud and water, improving the tire's mud and water drainage performance; secondly, compared to larger tread grooves, the guide groove 40, located on the tread unit 20, ensures the rigidity of the tread unit 20, thus guaranteeing the overall rigidity of the tire and solving the problem of low overall rigidity in existing MT tires while achieving mud and water drainage performance. Furthermore, the second guide groove 402, positioned on the bottom wall of the first guide groove 401, creates a step height between them. This not only allows the guide groove 40 to further guide the discharge of mud and water, preventing accumulation on the tire surface and improving mud and water drainage performance, but also disperses stress concentration in the tread unit 20, reducing the risk of tread block cracking and breakage, and improving tire durability.

[0049] In this embodiment, the area of ​​the tread pattern accounts for 54% to 65% of the area of ​​the contact portion between the tire and the driving surface, and preferably the area of ​​the tread pattern accounts for 54% to 55% of the area of ​​the contact portion between the tire and the driving surface.

[0050] like Figure 2 and Figure 6As shown, there are multiple connecting longitudinal grooves 30, which are spaced apart along the width direction of the tire to divide the tread unit 20 into two shoulder tread blocks 21 and an intermediate tread block 22 located between the two shoulder tread blocks 21. Along the circumference of the tire, three adjacent connecting longitudinal grooves 30 and at least partially connecting transverse grooves 10 surround each other to form a longitudinal groove unit. There are at least two guide grooves 40, which are located on both sides of the centerline X of the tread 1 along the width direction of the tire, and at least two guide grooves 40 are located at both ends of the longitudinal groove unit. Among them, at least two guide grooves 40, longitudinal groove units and at least partially connecting transverse grooves 10 surround each other to form a guide channel 3, and two adjacent guide channels 3 are centrally symmetrically arranged along the width direction of the tire. In this way, the multiple connecting longitudinal grooves 30 can connect with the connecting transverse grooves 10, forming a large-scale drainage and mud-removal network channel on the tread 1, improving the tire's drainage and mud-removal performance. On the other hand, they can divide the tread unit 20 into multiple tread blocks in the tire's circumference, combining with the connecting transverse grooves 10 to enhance the gripping force between the tread 1 and the driving surface from multiple directions, improving the tire's traction performance. At the same time, the arrangement of the guide channels 3 allows mud and water between the tire and the driving surface to flow from the longitudinal groove unit to the two guide grooves 40 after entering the longitudinal groove unit, and then be thrown out of the tread 1 through the guide grooves 40. This design, from the longitudinal groove unit to the two guide grooves 40, and through the gradually changing groove width of the guide grooves 40, provides a good guiding effect for mud and water, improving the tire's drainage and mud-removal performance and handling performance.

[0051] In this embodiment, the two flow guide grooves 40 are located at both ends of the longitudinal groove unit.

[0052] In this embodiment, the connecting groove 10 is set at a certain angle to the center line X of the tire.

[0053] In this embodiment, the tread structure also includes five tread pitch units spaced apart along the tire circumference. Along the tire circumference, the pitches of the five pitch tread units 20 are different, so that multiple tread blocks are staggered. While balancing the rigidity and stress of the tread 1, it can also disrupt the flow direction of airflow in the grooves and reduce tire driving noise.

[0054] like Figure 2 and Figure 5As shown, along the circumference of the tire, at least two flow guide grooves 40 include a first flow guide groove 41 and a second flow guide groove 42. The distance between the first flow guide groove 41 and the tire shoulder is greater than the distance between the second flow guide groove 42 and the tire shoulder. The extension direction of the first flow guide groove 41 is set at a first angle A1 with the center line X, and the extension direction of the second flow guide groove 42 is set at a second angle A2 with the center line X. The first angle A1 and the second angle A2 satisfy: 55°≤A1≤60°, 20°≤A2≤25°. The three adjacent connected longitudinal channels 30 include a first longitudinal channel 31, a second longitudinal channel 32, and a third longitudinal channel 33 connected in sequence. The end of the first longitudinal channel 31 away from the second longitudinal channel 32 is connected to the first guide groove 41, and the end of the third longitudinal channel 33 away from the second longitudinal channel 32 is connected to the second guide groove 42. In the direction from the first guide groove 41 to the second guide groove 42, the width of the first longitudinal channel 31 gradually increases, and the width of the third longitudinal channel 33 gradually decreases. The widths of both the first longitudinal channel 31 and the third longitudinal channel 33 are smaller than the width of the second longitudinal channel 32. In this way, the guide grooves 40 set at both ends of the longitudinal groove unit are located on both sides of the centerline X of the tread 1. The guide grooves 40 are set at an angle with the centerline X, so that one end of the guide channel 3 extends towards the centerline and tends to the width of the tire, while the other end of the guide channel 3 deviates from the centerline and tends to extend circumferentially towards the tire. This allows the guide channel 3 to not only improve the lateral grip of the tire, thus improving the traction performance and braking stability of the tire on unpaved roads, but also to ensure that mud, gravel and other debris can be discharged quickly, avoiding blockage of the guide channel 3, improving the tire's drainage and mud removal performance, and reducing the damage to the tread blocks caused by debris getting stuck in the guide channel 3, thereby extending the tire's service life. Meanwhile, the groove widths of the first longitudinal groove 31, the second longitudinal groove 32, and the third longitudinal groove 33 are designed to give the groove units a shape that gradually narrows from the middle to both ends. On the one hand, this allows more mud and water to enter the middle part when the tire contacts the driving surface. Then, during the rolling process of the tire, the mud and water can be quickly squeezed to both ends, avoiding blockage in the groove units and ensuring smooth drainage and mud removal in the guide channel 3. It also reduces the damage to the tread blocks caused by debris getting stuck in the groove units, thus extending the tire's service life. On the other hand, the gradually changing groove width evens out the ground pressure of the tread blocks, ensuring the tire's traction and handling performance.

[0055] In this embodiment, the value of the first included angle A1 satisfies: A1=57°, to ensure that the value of the first included angle A1 is more appropriate.

[0056] In this embodiment, the value of the second included angle A2 satisfies: A2=22°, to ensure that the value of the second included angle A2 is more appropriate.

[0057] like Figure 5As shown, the first longitudinal ditch 31 includes a first sub-longitudinal ditch 311 and a second sub-longitudinal ditch 312 that are interconnected. The ends of the first sub-longitudinal ditch 311 and the second sub-longitudinal ditch 312 that are away from each other are respectively connected to two adjacent interconnected transverse ditches 10. The extension direction of the first sub-longitudinal ditch 311 is set at a third angle A3 with respect to the center line X, and the extension direction of the second sub-longitudinal ditch 312 is set at a fourth angle A4 with respect to the center line X. The third angle A3 and the fourth angle A4 satisfy: 70°≤A3≤75°, 38°≤A4≤43°; and / or, the extension direction of the second longitudinal ditch 312 is set at a fifth angle A5 with respect to the center line X. 5. Satisfying: 35°≤A5≤40°, the second longitudinal ditch 32 is bent on one side wall near the center line X; and / or, the third longitudinal ditch 33 includes a third sub-longitudinal ditch 331 and a fourth sub-longitudinal ditch 332 that are interconnected, the ends of the third sub-longitudinal ditch 331 and the fourth sub-longitudinal ditch 332 that are away from each other are respectively connected to two adjacent connecting transverse ditches 10, the extension direction of the third sub-longitudinal ditch 331 is set at a sixth angle A6 with the center line X, and the extension direction of the fourth sub-longitudinal ditch 332 is set at a seventh angle A7 with the center line X, the sixth angle A6 and the seventh angle A7 satisfy: 0°≤A6≤5°, 25°≤A7≤30°. Thus, the first sub-groove 311 and the second sub-groove 312 cause the first groove 31 to be bent, and the third sub-groove 331 and the fourth sub-groove 332 cause the third groove 33 to be bent. The bent sidewall of the second groove 32 ensures smooth connection between the first groove 31 and the third groove 33. This arrangement causes the portion of the groove unit near the first guide groove 41 to tend to extend along the tire width direction. Combined with the guide channel 3 passing through the centerline X, this allows the tread blocks at the center of the tire's contact with the road surface to interlock, enhancing the rigidity of the tread blocks, reducing the risk of tread block breakage, improving the lateral grip in the center of the tire tread 1, and enhancing the tire's traction and braking stability. Simultaneously, this arrangement also causes the portion of the groove unit near the second guide groove 42 to tend to extend along the tire's circumference. Furthermore, since the guide channel 3 passes through the center line X, the part of the tire tread 1 near the shoulder can ensure the rigidity of the shoulder tread block 21, while also ensuring that the guide channel 3 is inclined in the circumferential direction of the tire, which is conducive to the discharge of mud, gravel and other debris. This improves the tire's water drainage and mud discharge performance, reduces the risk of debris getting stuck in the guide channel 3, reduces the risk of tire tread block breakage, and further extends the tire's service life.

[0058] In this embodiment, the value of the third included angle A3 satisfies: A3=71°, to ensure that the value of the third included angle A3 is more appropriate.

[0059] In this embodiment, the value of the fourth included angle A4 satisfies: A4=40°, to ensure that the value of the fourth included angle A4 is more appropriate.

[0060] In this embodiment, the value of the fifth included angle A satisfies: A5 = 37°, to ensure that the value of the fifth included angle A is more appropriate.

[0061] In this embodiment, the value of the sixth included angle A6 satisfies: A6=2°, to ensure that the value of the sixth included angle A6 is more appropriate.

[0062] In this embodiment, the value of the seventh included angle A7 satisfies: A7=29°, to ensure that the value of the seventh included angle A7 is more appropriate.

[0063] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, along the direction from the first guide groove 401 to the second guide groove 402, the width of the second guide groove 402 gradually decreases so that the second guide groove 402 forms a conical structure. Wherein, along the direction perpendicular to the tread 1, the groove depth D11 of the first guide groove 401 and the groove depth D12 of the second guide groove 402 satisfy: 2mm≤D11≤5mm, 5mm≤D12≤15mm; and / or, along the direction from the connecting longitudinal groove 30 to the guide groove 40, the length L1 of the first guide groove 401 satisfies: 15mm≤L1≤25mm; and / or, along the direction from the connecting longitudinal groove 30 to the guide groove 40, the end of the first guide groove 401 away from the connecting longitudinal groove 30 and the end of the second guide groove 402 away from the connecting longitudinal groove 30 have a maximum distance C1, and the maximum distance C1 satisfies: 2mm≤C1≤5mm; and / or, the maximum groove width W1 of the second guide groove 402 satisfies: 5mm≤W1≤15mm. In this way, the above-mentioned arrangement allows the second guide channel 402 to form a triangular pyramid-like structure, creating a backflow channel that helps mud and water pass through. This allows the second guide channel 402 to accommodate additional mud and water, preventing mud and water from accumulating on the tread surface 1 and causing a loss of tire grip, thus ensuring tire handling reliability. Simultaneously, the second guide channel 402, in conjunction with the first guide channel 401, guides mud and water while maintaining the rigidity of the tread blocks, ensuring tire rigidity. Furthermore, the arrangement of the length L1 and maximum distance C1 of the first guide channel 401 makes the placement of the second guide channel 402 within the first guide channel 401 more suitable, resulting in a more rational stepped surface between the first and second guide channels 401. This increases the mud and water drainage area of ​​the guide groove 40, allowing for rapid mud discharge even when the tire is deep in muddy terrain, preventing clogging of the guide groove 40 and improving tire handling reliability.

[0064] In this embodiment, the groove depth D11 of the first guide groove 401 satisfies: D11=3mm, to ensure that the value of the groove depth D11 of the first guide groove 401 is more appropriate.

[0065] In this embodiment, the groove depth D12 of the second guide groove 402 satisfies: D12=10mm, to ensure that the value of the groove depth D12 of the second guide groove 402 is more appropriate.

[0066] In this embodiment, the length L1 of the first guide channel 401 satisfies: L1=20mm, to ensure that the value of the length L1 of the first guide channel 401 is more appropriate.

[0067] In this embodiment, the maximum distance C1 satisfies: C1=3mm, to ensure that the value of the maximum distance C1 is more appropriate.

[0068] In this embodiment, the maximum width W1 of the second guide channel 402 satisfies: W1=10mm, to ensure that the value of the maximum width W1 of the second guide channel 402 is more appropriate.

[0069] like Figure 2 As shown, the tread structure also includes short sipes 50 and connecting sipes 60. The short sipes 50 are disposed on at least one tread unit 20, with one end connected to the guide groove 40 and the other end spaced apart from the connecting transverse groove 10. Alternatively, the connecting sipes 60 are disposed on at least one intermediate tread block 22, and the connecting sipes 60 include a first sub-sipe 61 and a second sub-sipe 62 that are interconnected. The ends of the first sub-sipes 61 and the second sub-sipes 62 that are furthest from each other are respectively connected to two adjacent connecting transverse grooves 10. The first sub-sipes 61 and the second sub-sipes 62 are arranged at an angle. This arrangement of the short sipes 50 can break the water film between the area between the edge of the tread block and the guide groove 40 and the driving surface, increasing the friction between the tread block and the driving surface and improving the tire's wet handling. Meanwhile, the arrangement of the first sub-groove 61 and the second sub-groove 62 makes the connecting groove 60 bend in shape. This allows the connecting groove 60 to cut through the water film between the tread block and the driving surface, increasing the friction between the tread block and the driving surface. At the same time, compared with setting a larger groove, it can also balance the rigidity of the tread block and improve the handling of the tire.

[0070] like Figure 2As shown, the tread structure also includes reinforcing protrusions 70, which are disposed on the bottom wall of the connecting transverse groove 10, with at least a portion of the reinforcing protrusions 70 located at the tire shoulder. The width W2 of the reinforcing protrusions 70 satisfies: 2mm ≤ W2 ≤ 4mm; and / or, the height H1 of the reinforcing protrusions 70 satisfies: 1mm ≤ H1 ≤ 4mm. This arrangement of the reinforcing protrusions 70 prevents gravel from becoming embedded in the connecting transverse groove 10, thus avoiding compression and damage to the tread blocks and groove walls, ensuring the wear resistance of the tread blocks, guaranteeing the tire's off-road durability, and extending its service life. Simultaneously, the arrangement of the reinforcing protrusions 70 ensures smooth mud and stone removal from the connecting transverse groove 10, reducing the degree of obstruction to mud removal and guaranteeing the tire's grip stability under complex terrain conditions.

[0071] In this embodiment, the width W2 of the reinforcing protrusion 70 satisfies: W2=3.5mm, to ensure that the value of the width W2 of the reinforcing protrusion 70 is more appropriate.

[0072] In this embodiment, the height H1 of the reinforcing protrusion 70 satisfies: H1=2mm, to ensure that the value of the height H1 of the reinforcing protrusion 70 is more appropriate.

[0073] In this embodiment, there are two reinforcing protrusions 70 in one of the two adjacent connecting transverse grooves 10, and the two reinforcing protrusions 70 are spaced apart along the extending direction of the connecting transverse groove 10.

[0074] like Figure 2 and Figure 7 As shown, the tread pattern has a contact surface with the driving surface. Along the width direction of the tire, the contact surface has two contact edges, with a width T between the two contact edges. The shoulder tread block 21 has an edge near the tire shoulder. Along the circumference of the tire, one of two adjacent edges is located at the tire shoulder, and the other of the two adjacent edges is spaced apart from the tire shoulder. Along the width direction of the tire, there is a distance S1 between two adjacent edges, and the distance S1 and the width T satisfy: 0.025T≤S1≤0.05T. Thus, the distance S1 between the edges of two adjacent shoulder tread blocks 21 can form additional drainage and mud-removing grooves at the tire shoulder, which, in conjunction with the connecting transverse groove 10, accelerates the drainage of water and mud between the tire shoulder and the driving surface, reducing the risk of hydroplaning and improving the tire's mud-removing and drainage performance and wet-weather handling performance. Meanwhile, the setting of the spacing S1 can also increase the gap of the tread grooves at the tire shoulder, reduce the risk of debris such as gravel and mud getting stuck at the tire shoulder, reduce the wear of the tire shoulder, and improve the wear resistance of the tire.

[0075] In this embodiment, the spacing S1 and the width T satisfy the following condition: S1 = 0.035T.

[0076] like Figure 1 , Figure 2 , Figure 4 , Figures 10 to 14As shown, the tire also has two sidewalls 2, which are connected to the opposite ends of the tread 1. The sidewalls 2 are provided with a first tread structure 80 protruding from the sidewalls 2. The first tread structure 80 includes at least two first guide treads 81 and second guide treads 82. One end of the first guide tread 81 is connected to the shoulder tread block 21, and the other end of the first guide tread 81 is spaced apart from the end of the sidewall 2 away from the tread 1. At least two first guide treads 81 are arranged opposite each other to form a guide recess 811. The second guide tread 82 is disposed within the guide recess 811. The second guide tread 82 includes at least two interconnected guide sections 821. The ends of the at least two guide sections 821 away from each other are respectively connected to two adjacent shoulder tread blocks 21. The at least two guide sections 821 are arranged at an angle so that the second guide tread 82 forms a pointed tip away from the tread 1. The first guide tread 81 has a short recess 812. One end of the short recess 812 extends into the guide recess 811, and the other end of the short recess 812 is spaced apart from the side of the first guide tread 811. Along the direction from the second guide tread 82 to the first guide tread 81, the groove width of the guide recess 811 gradually decreases. The two sidewalls of 11 are set at an eighth included angle A8, which satisfies: 50°≤A8≤65°; and / or, the guide section 821 has a first inclined surface 8211 and a second inclined surface 8212 connected to each other, the first inclined surface 8211 is located on the side of the second inclined surface 8212 away from the tread 1, the first inclined surface 8211 and the sidewall 2 are set at a ninth included angle A9, and the second inclined surface 8212 and the sidewall 2 are set at a tenth included angle A10, which satisfies: 120°≤A9≤140°, 60°≤A10≤90°; and / or, the maximum height H2 of the guide section 821 satisfies: 5mm≤H2≤10mm. In this way, the first sidewall structure 80 set on the sidewall 2 guides the mud and water on the tread 1 to the sidewall 2 through the guide recesses 811 formed by the two first guide sidewalls 81. Combined with the protruding arrangement of the second guide sidewall 82, it forms an arrow-like structure, which allows the mud and sand at the tire shoulder and sidewall 2 to be discharged in a directional manner along the arrow structure, avoiding the accumulation and blockage of mud and sand on the sidewall 2 and improving the mud and water drainage performance of the tire. At the same time, the angle between the first inclined surface 8211 of the guide section 821 and the sidewall 2 is large, which is conducive to the mud and sand entering the guide recesses 811 and reducing the flow resistance of the mud and sand. The angle between the second inclined surface 8212 and the sidewall 2 is small, which can narrow the flow channel of the mud and sand, forming a wide rib and narrow protrusion guide effect with the first inclined surface 8211, improving the mud and water drainage efficiency of the sidewall 2.Meanwhile, the large angle setting of the first inclined surface 8211 can replace the sharp edge of the tread block, reducing the risk of direct impact and cuts from rocks and gravel to the tire sidewall 2, dispersing the stress when the tire sidewall 2 comes into contact with foreign objects, avoiding bulging and tearing of the tire sidewall 2 caused by local stress, improving the wear resistance of the tire sidewall 2, and extending the service life of the tire.

[0077] In this embodiment, the value of the eighth included angle A8 satisfies: A8=60°, to ensure that the value of the eighth included angle A8 is more appropriate.

[0078] In this embodiment, the value of the ninth included angle A9 satisfies: A9=138°, to ensure that the value of the ninth included angle A9 is more appropriate.

[0079] In this embodiment, the value of the tenth included angle A10 satisfies: A10=80°, to ensure that the value of the tenth included angle A10 is more appropriate.

[0080] In this embodiment, the maximum height H2 of the guide section 821 satisfies: H2=8mm, to ensure that the value of the maximum height H2 is more appropriate.

[0081] In this embodiment, two first guide flowers 81 are provided.

[0082] It should be noted that the number of first guide flowers 81 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of first guide flowers 81 can be three, four, six, nine, or more.

[0083] In this embodiment, the first guide flower 81 is bent, and the bent protrusion is located away from the tread 1.

[0084] In this embodiment, the first guide flower 81 has a chamfer, and the chamfer is set at an eleventh angle A11 with the tire sidewall 2. The eleventh angle A11 satisfies: 25°≤A11≤35°. Preferably, the eleventh angle A11 is set at 30°.

[0085] like Figure 2 and Figure 4As shown, there are multiple first lateral camber structures 80, which are spaced apart circumferentially along the tire sidewall. The sidewall 2 also has a second lateral camber structure 90 protruding from it, located between adjacent first lateral camber structures 80. The second lateral camber structure 90 includes a first lateral camber portion 91 and a second lateral camber portion 92 connected in sequence along a direction perpendicular to the sidewall 2. The projection of the second lateral camber portion 92 onto the first lateral camber portion 91 is located within the first lateral camber portion 91, creating a stepped surface between the first lateral camber portion 91 and the second lateral camber portion 92. In this way, the second lateral camber structure 90 can divert mud and sand between adjacent first lateral camber structures 80, further improving the mud and water drainage performance of the sidewall 2. It can also further disperse the stress when the sidewall 2 comes into contact with foreign objects, further improving the wear resistance of the sidewall 2 and extending its service life.

[0086] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0087] The tire tread has a tread pattern structure with multiple connecting transverse grooves spaced apart along the tire's circumference to divide the tread into multiple tread units. Connecting longitudinal grooves are provided on at least one tread unit, with each end of the longitudinal groove connecting to two adjacent connecting transverse grooves. A flow guide groove is provided on at least one tread unit, with one end connected to a connecting longitudinal groove via one of the two adjacent connecting transverse grooves, and the other end spaced apart from the other of the two adjacent connecting transverse grooves. The flow guide groove includes a first flow guide channel and a second flow guide channel disposed on the bottom wall of the first flow guide channel. Along the direction from the connecting longitudinal groove to the flow guide groove, the width of both the first and second flow guide channels gradually decreases. This arrangement of multiple interconnected transverse grooves serves two main purposes: firstly, it effectively drains water, mud, and gravel from between the tire tread and the ground, ensuring excellent mud and water drainage and self-cleaning performance; secondly, it allows the tire tread blocks to better embed themselves in muddy ground, increasing friction between the tire and the ground, thus ensuring tire grip, preventing tire slippage, maintaining traction, and guaranteeing driving stability and safety. Simultaneously, the interconnected longitudinal grooves, combined with the interconnected transverse grooves, form mud drainage channels, expanding the drainage path for water and mud and further enhancing mud and water drainage performance. Furthermore, the guide grooves, connected to the longitudinal and transverse grooves, create efficient flow channels, facilitating the smooth ejection of mud and water and improving mud and water drainage performance. Moreover, compared to larger tread grooves, the guide grooves, located on the tread unit, ensure the rigidity of the tread unit and the overall rigidity of the tire, thereby solving the problem of low overall rigidity in existing MT tires while achieving excellent mud drainage performance. Meanwhile, the way the second guide channel is set on the bottom wall of the first guide channel creates a certain step height between the second guide channel and the first guide channel. This not only allows the guide channel to further guide the discharge of mud and water, avoiding the accumulation of mud and water on the tire surface and improving the tire's mud and water discharge performance, but also disperses the stress concentration phenomenon of the tread unit, reduces the risk of tread block cracking and falling off, and improves the tire's durability.
