[0022] The present invention will now be described in detail with reference to specific embodiments. It should be noted that these embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments based on the above description of the present invention.

[0023] Figure 1 The vertical direction is the longitudinal direction, which is also the tire's circumference. The direction perpendicular to it is the lateral direction, which is also the tire's axial direction.

[0024] like Figures 1-4As shown, an anti-wear patterned block 5 includes an upper side I 50, a lower side I 51, and two side sides I 52. The side sides I 52 are arranged longitudinally, while the upper side I 50 and the lower side I 51 are arranged parallel to each other. The upper side I and the lower side I each include a side I 53 and a side II 54, respectively. One end of the side I 53 and the side II 54 are connected to each other, and the other end is connected to different side sides I 52. The projection lengths of the side sides I 53 and the side II 54 in the transverse direction are different. The anti-wear patterned block is also provided with a groove I 55 and a groove II 56, one end of the groove I 55 and the groove II 56 are connected to each other, and the other end is connected to different side sides I 52. The angle between the side I 53 and the longitudinal direction is α, and the angle between the side II 54 and the longitudinal direction is α. The included angle is b, the included angle between the groove I 55 and the longitudinal direction is c, the included angle between the groove II 56 and the longitudinal direction is d, the included angle a is the same as the included angle d, the included angle b is the same as the included angle c, the side I 53 and the groove II 56 have the same length but are not parallel, the side II 54 and the groove I 55 have the same length but are not parallel; the intersection point of the side I 53 and the side II 54 is A, the intersection point of the groove I 55 and the groove II 56 is C, the anti-wear pattern block 5 is also provided with a longitudinal groove, one end of the longitudinal groove I 57 is the intersection point A, and the other end point is located on the groove I, one end of the longitudinal groove II 58 is the intersection point C, and the other end point is located on the side II 54, the endpoints A and C of the longitudinal groove I 57 and the longitudinal groove II 58 are uniformly located at the upper or lower end of the longitudinal groove.

[0025] Since angle a and angle d are the same, angle b and angle c are the same, edge I 53 and groove II 56 have the same length but are not parallel, and edge II 54 and groove I 55 have the same length but are not parallel, c and d are not labeled in the figure.

[0026] The tread blocks are divided into two quadrilaterals (7) and two pentagons (8) by sipes I, sipes II, longitudinal sipes I, longitudinal sipes II, edge sipes I and II, and both side edges. The pentagons and quadrilaterals are interspersed, which reduces uneven wear and improves eccentric wear. Furthermore, the design of sipes I, sipes II, longitudinal sipes I, and longitudinal sipes II on the tread blocks also provides good heat dissipation, wet and snow performance, thus providing good durability. Sipes I and II enhance tire grip, water drainage, traction, and handling precision.

[0027] The angle α between side I and the longitudinal direction is 110-116°, and the angle b between side II and the longitudinal direction is 60-65°. With this angle design, the pentagon and quadrilateral are designed to resemble a shield, making them more robust and wear-resistant, and reducing uneven wear to a greater extent.

[0028] The ratio of the lateral projection lengths of edge I53 and edge II54 on the same tread block is 0.75-0.82. This design helps prevent sideslip and improves tire handling.

[0029] The longitudinal grooves I and II on the same patterned block have the same length.

[0030] The depth of the cutting groove I 55, cutting groove II 56, longitudinal cutting groove I 57, and longitudinal cutting groove II 58 is 1.5mm-2.5mm, and the width is 0.5-0.7mm.

[0031] Quadrilateral 7 is filled with knurled 70.

[0032] The knurling 70 includes three or more strip-shaped grooves 71 arranged in parallel, with an interval of 0.7-0.9 mm between adjacent grooves; the width of the grooves is 0.7-0.9 mm; and the angle e between the strip-shaped grooves 71 and the longitudinal direction is 43-47°. Knurling on the tread ensures the tire's mileage.

[0033] A tire comprising the aforementioned anti-wear tread blocks.

[0034] A tire has a tread pattern comprising tread strips and tread grooves 1 arranged along the tire circumference. Tread blocks and tread grooves are spaced apart in the tire's transverse direction. In the tire's transverse direction, from the center to both sides, the tread blocks are arranged in sequence as a center tread strip 2, an intermediate tread strip 3, and a shoulder tread strip 4. Along the tire's circumference, at least three anti-uniform wear tread blocks 5 are provided on the intermediate tread strip 3. On the same intermediate tread strip, the side portion of the anti-uniform wear tread block 5 forms a corresponding tread groove wall, and tread grooves are formed between adjacent anti-uniform wear tread blocks. The tread groove walls form the upper edge 50 and the lower edge 51 of the anti-uniform wear tread block 5.

[0035] The groove depth between the anti-uniform wear tread blocks is greater than the depth of the sipes I, sipe II, longitudinal sipes I, and longitudinal sipes II on the anti-uniform wear tread blocks. This can ensure tire mileage while reducing rolling resistance in the early stages of tread use. The angles of the grooves, sipes I, sipes II, longitudinal sipes I, and longitudinal sipes II can balance handling performance, making driving more stable, and reducing uneven wear (feather-like wear) that occurs during tire use.

[0036] The depth of the patterned grooves is 3.5mm-4.5mm, and the width is 0.5-0.7mm.

[0037] The tread grooves and sipes I, II, longitudinal sipes I, and II have different depths but the same width. Moreover, only the tread grooves and sipes I, II, and longitudinal sipes I and II are set on the middle tread strip. This can ensure the tire's mileage performance while reducing the rolling resistance in the early stages of tread use.

[0038] The tread grooves extend longitudinally and are straight grooves with variable wall angles. This longitudinal extension ensures the vehicle's straight-line driving capability while also providing high heat dissipation and relatively low rolling resistance.

[0039] The grooves are designed with the same width.

[0040] The depth of the grooves ranges from 15 to 17 mm, and the width ranges from 11 to 13 mm.

[0041] The tread groove depth is 88-92% of the tread rubber thickness, which can ensure the tire's traction and water drainage.

[0042] Using tread grooves of the same width can effectively increase the tire's ability to prevent uneven wear. Using four tread grooves can effectively increase the product's mileage. The depth of the tread grooves set in this application can improve mileage performance and ensure the tire's traction and water drainage.

[0043] The tread groove 1 features a dragon scale texture design, which effectively reduces tire noise while ensuring the tire's wet grip performance.

[0044] The central tread pattern strip 2 has oblique grooves, with both ends of the oblique grooves connected to the tread pattern grooves. The central tread pattern strip 2 is divided into a central tread pattern block 6 by oblique sipes 20. The central tread pattern block 6 has sipes Ⅲ 60 that divide the central tread pattern block into two parts. Sipes Ⅲ 60 includes sipes Ⅳ 61, Ⅴ 62, and Ⅵ 63. Sipes Ⅳ and Ⅵ are arranged longitudinally, while sipe Ⅴ 62 is arranged obliquely. Both ends of sipe Ⅴ 62 are connected to one end of sipes Ⅳ and Ⅵ, respectively. The other ends of sipes Ⅳ 61 and Ⅵ 62 are connected to the oblique grooves 20 on the upper part Ⅱ 64 and lower part Ⅱ 65 of the central tread pattern block, respectively. Sipes Ⅲ 60 divide the central tread pattern block into two hexagons 9, providing excellent handling and wet grip performance. Furthermore, the sipes III on the center tread block provide excellent heat dissipation, wet and snow performance, thus enhancing durability. The angled grooves and sipes V improve tire grip, water drainage, and traction.

[0045] The oblique groove 20 forms the upper edge II 64 and lower edge II 65 of the central patterned block on its wall, and the patterned groove 1 forms the side edge II 66 of the central patterned block on its wall. Since the patterned groove extends in the longitudinal direction, the side edge II 66 of the central patterned block is also in the longitudinal direction. Due to the oblique groove 20, the upper edge II and the lower edge II are parallel oblique edges.

[0046] The angle f between the oblique groove 20 and the longitudinal direction is 60-65°. That is, the angle between the upper edge II and the lower edge II of the central pattern block and the longitudinal direction.

[0047] The angle g between the tool groove V and the longitudinal direction is 48-53°.

[0048] The depth of the slanted groove is 3.5mm-4.5mm, and the width is 0.5-0.7mm.

[0049] The depth of grooves IV, V, and VI is 1.5mm-2.5mm, and the width is 0.5-0.7mm.

[0050] The oblique grooves and sipes III have different depths but the same width. Moreover, only oblique grooves and sipes III are set on the center tread strip. This can ensure the tire's mileage performance while reducing the rolling resistance in the early stages of tread use.

[0051] The depth of the oblique grooves between the center tread blocks is greater than the depth of groove III on the center tread block. This can ensure tire mileage while reducing rolling resistance in the early stages of tread use. The angles of the oblique grooves and groove III can balance handling performance, making driving more stable, and reducing uneven wear (feathering wear) that occurs during tire use.

[0052] The oblique sipes and the sipe II on one side of the middle tread strip are on the same straight line. Two adjacent oblique sipes and two adjacent sipe II on one side of the middle tread strip are each on the same straight line. This optimizes the force transmission path and improves the tire's water drainage performance.

[0053] To improve wear resistance, a suitable tire shoulder width of 40-45mm is selected. Simulation results show that the tire shoulder width provided in this application improves anti-uneven wear performance by 10-15%.

[0054] The shoulder tread pattern does not have sipes or grooves, only the logo "10". The absence of sipes and grooves, along with the continuous rubber structure, increases the circumferential stiffness of the tire shoulder by 40-60%. Simultaneously, the absence of grooves and grooves, which are stress concentration areas, prevents tearing stress at the groove edges, thus improving resistance to uneven wear.

[0055] The tread pattern is symmetrical and features a two-way design. This symmetrical, two-way tread design ensures symmetrical distribution of ground contact pressure, reduces lateral offset force, supports cross-rotation, and can significantly increase mileage.

[0056] The tread pattern is designed with equal pitch, which can reduce pitch stress difference and better uniform wear.

[0057] The tread pattern 12 consists of 67 pitches.

[0058] In this application, the oblique grooves, cutter grooves III, I, II, longitudinal cutter grooves I, II, and patterned grooves are all formed of steel sheets. Schematic diagrams of steel sheet structures at different depths are shown below. Figure 2 As shown.

[0059] The grooves on the tread pattern, and the connection between the grooves and the tread grooves, facilitate the improvement of tire grip, water drainage, and driving performance.

[0060] The tires provided in this application are primarily intended as fuel-efficient, long-distance anti-wear guide tires, but can also be used as all-wheel tires.

It should be noted that for those skilled in the art and any person skilled in the art, any equivalent substitutions or changes made to the technical solution and inventive concept of the present invention without departing from the overall concept of the present invention, as well as any changes and improvements made, should also be considered within the scope of protection of the present invention.
