This improves the tire's snow removal, water drainage, and mud removal performance, further enhances the tire's handling and driving safety, and thus solves the problem of low driving safety of existing tires on icy and snowy roads.

[0021] To address the issue of low safety of existing tires on icy and snowy roads, this application provides a tire.

[0022] like Figure 1As shown, the tire tread has a tread pattern, which includes multiple lateral groove groups 1 and longitudinal groove groups 20. The multiple lateral groove groups 1 are arranged sequentially along the circumference of the tire. Each lateral groove group 1 includes a first lateral groove 11 and a second lateral groove 12 that are interconnected. At least a portion of the first lateral groove 11 and the second lateral groove 12 are located on opposite sides of the tire's center surface S, forming a herringbone structure. The longitudinal groove groups 20 include multiple longitudinal grooves spaced apart along the width of the tire. These longitudinal grooves are positioned between adjacent lateral groove groups 1, and their ends are connected to the two adjacent lateral groove groups 1. Specifically, along the circumference of the tire, adjacent lateral groove groups 1 include a first lateral groove group 101 and a second lateral groove group 102. The first lateral groove 11 of the first lateral groove group 101 is connected to and adjacent to the first lateral groove 11 of the second lateral groove group 102, and the second lateral groove 12 of the first lateral groove group 101 is adjacent to the first lateral groove 11 of the second lateral groove group 102.

[0023] Applying the technical solution of this embodiment, the tire tread is provided with a tread pattern structure. Multiple transverse groove groups 1 of the tread pattern structure are arranged sequentially along the circumference of the tire. Each transverse groove group 1 includes a first transverse groove 11 and a second transverse groove 12 that are interconnected. At least a portion of the first transverse groove 11 and the second transverse groove 12 are located on opposite sides of the tire's center surface S, so that the transverse groove groups 1 form a "V" shaped structure. The longitudinal groove group 20 includes multiple longitudinal grooves spaced apart along the width direction of the tire. The longitudinal grooves are located between two adjacent transverse groove groups 1, and both ends of the longitudinal grooves are connected to the two adjacent transverse groove groups 1. Specifically, along the circumference of the tire, two adjacent transverse groove groups 1 include a first transverse groove group 101 and a second transverse groove group 102. The first transverse groove 11 of the first transverse groove group 101 is connected to and adjacent to the first transverse groove 11 of the second transverse groove group 102, and the second transverse groove 12 of the first transverse groove group 101 is adjacent to the first transverse groove 11 of the second transverse groove group 102. The arrangement of the first and second transverse grooves 11 and 12, forming a "V" shape, serves two purposes. First, it allows the tire tread blocks to better embed into the ground, increasing the friction between the tire and the ground, thus ensuring tire grip, preventing tire slippage, maintaining tire traction, and guaranteeing driving safety. Second, it effectively removes ice, snow, and wastewater from the tire tread, ensuring the tire's snow removal, water drainage, and mud removal capabilities, thus guaranteeing wet-weather handling performance and further increasing friction between the tire and the ground, enhancing driving safety. Simultaneously, the arrangement of multiple longitudinal grooves, working in conjunction with the transverse groove group 1, further removes ice, snow, and wastewater, increasing friction between the tire and the ground and improving wet-weather handling and driving safety. Meanwhile, the connection between the first transverse groove 11 of the first transverse groove group 101 and the first transverse groove 11 of the second transverse groove group 102, as well as the arrangement of the second transverse groove 12 of the second transverse groove group 102, can form a complete snow removal, water drainage, and mud removal network with the longitudinal groove group 20 on the tire tread, improving the tire's snow removal, water drainage, and mud removal performance, further enhancing the tire's handling and driving safety, and thus solving the problem of low driving safety of existing tires on icy and snowy roads.

[0024] In this embodiment, at least a portion of the first transverse groove 11 is arc-shaped; and / or, at least a portion of the second transverse groove 12 is arc-shaped.

[0025] like Figure 1As shown, the first transverse groove 11 includes a first sub-transverse groove 111 and a second sub-transverse groove 112 that are interconnected. The first sub-transverse groove 111 passes through the center plane S and is located on one side of the center plane, while the second sub-transverse groove 112 is located on the other side of the center plane. The depth G1 of the first sub-transverse groove 111 and the depth G2 of the second sub-transverse groove 112 satisfy the following condition: 0.48G2≤G1≤0.52G2. This arrangement of the first sub-transverse grooves 111 and 112 serves two purposes: firstly, it allows for the drainage of snow and water between the tire and the road surface, ensuring the tire's snow removal, water drainage, and mud removal performance; secondly, it ensures sufficient grip between the tire and the road surface while maintaining the rigidity of the tire tread blocks through different groove depths, thus guaranteeing the tire's traction and braking performance in the straight direction, ensuring tire handling, and improving tire driving safety.

[0026] In this embodiment, the depth G2 of the second sub-lateral groove 112 is the maximum groove depth of the tire.

[0027] like Figure 1 As shown, the width of the second sub-cross groove 112 gradually increases along the direction from the first sub-cross groove 111 to the second sub-cross groove 112; and / or, the width of the second cross groove 12 gradually increases along the direction from one end of the second cross groove 12 near the center plane S to the other end away from the center plane S. The depth G3 of the second cross groove 12 is the same as the depth G2 of the second sub-cross groove 112.

[0028] like Figure 1 As shown, the tread structure also includes lateral sipes 30, which are positioned between two adjacent transverse groove groups 1. At least some of the lateral sipes 30 are arranged in a zigzag or wavy shape. This arrangement of the lateral sipes 30 serves two purposes: firstly, it separates the tread blocks, increasing the contact area between the tire and the ground, making it easier for the tire to embed itself in icy or snowy conditions, thus improving braking performance and driving safety; secondly, it ensures the compactness of the tread blocks, reducing their rigidity and deformation, thereby enhancing tire grip. Furthermore, the shape of the lateral sipes 30 balances the rigidity of the tire tread blocks in both the circumferential and width directions, further ensuring the tire's traction on snow.

[0029] In this embodiment, the transverse groove 30 is a fine groove formed by a steel sheet.

[0030] Specifically, the length of the lateral sipes 30 is less than 10mm. In this way, the tire tread blocks are continuously sheared and deformed during rolling. The shallow depth of the lateral sipes 30, with a length of less than 10mm, ensures the rigidity of the tread blocks, effectively prevents the tread blocks from tearing during tire rolling, ensures the tire's wear resistance, and extends the tire's service life.

[0031] like Figure 1 As shown, multiple lateral groove groups 1 divide the tread into multiple tread sections 40, and lateral sipes 30 are provided on the tread sections 40. There are multiple lateral sipes 30, spaced apart along the circumference and width directions of the tire. Specifically, along the circumference of the tire, the distance P between two adjacent lateral sipes 30 on each tread section 40 satisfies: 4mm ≤ P ≤ 5mm. This arrangement makes the layout of the lateral sipes 30 more suitable, ensuring the rigidity of the tread section 40, improving the grip of the tread section 40, and ensuring good grip at all angles and positions where the tire contacts the ground, thus improving tire handling. At the same time, the distance P between two adjacent lateral sipes 30 ensures a more suitable density of lateral sipes 30, avoiding an impact on tire handling due to too many or too few lateral sipes 30, and ensuring tire driving safety.

[0032] like Figure 1 As shown, multiple longitudinal grooves include first longitudinal grooves 21, which are disposed on the tread portion 40. There are multiple first longitudinal grooves 21, spaced apart along the width direction of the tire, dividing the tread portion 40 into two shoulder tread portions 41 and an intermediate tread portion located between the two shoulder tread portions 41. The lateral sipes 30 disposed on the intermediate tread portion extend perpendicularly to the tire's direction of travel, while the lateral sipes 30 disposed on the shoulder tread portions 41 extend in the same direction as the shoulder tread portions 41. Thus, the lateral sipes 30 disposed on the intermediate tread portion increase the contact points between the intermediate tread portion and the ground, improving the grip of the intermediate tread portion and ensuring the stability of the tire during straight-line travel. Meanwhile, the sipes provided on the shoulder tread section 41 disperse the rigidity of the tread blocks of the shoulder tread section 41, ensuring the grip of the shoulder tread section 41, improving the lateral grip of the tire, further improving the tire's handling performance, and enhancing the tire's passability and safety on icy and snowy roads in winter.

[0033] In this embodiment, the tire's direction of travel is the same as the direction in which the tire rolls during vehicle travel.

[0034] In this embodiment, as many transverse grooves as possible are arranged in the multiple transverse grooves provided on the tire shoulder tread portion 41, with the distance between two adjacent transverse slits 30 not less than 4.5mm, in order to balance the rigidity of the tread blocks of the tire shoulder tread portion 41.

[0035] like Figure 1As shown, a recess 50 is provided on the shoulder tread portion 41. One end of the recess 50 extends to the transverse groove group 1, and the other end of the recess 50 is spaced apart from the side of the shoulder tread portion 41. The extending direction of the recess 50 is parallel to the extending direction of the first longitudinal groove 21. Thus, the recess 50 on the shoulder tread portion 41 helps to expel snow and mud accumulated between the shoulder tread portion 41 and the driving surface, improving the snow removal, water drainage, and mud removal performance of the shoulder tread portion 41, and enhancing the tire's wet handling and braking performance.

[0036] like Figure 1As shown, the multiple longitudinal grooves include second longitudinal grooves 22, which are disposed on the intermediate tread portion. There are multiple second longitudinal grooves 22, which are spaced apart along the width direction of the tire to divide the intermediate tread portion into a central tread portion 42 and a crown tread portion 43. At least a portion of the central tread portion 42 passes through the center surface S, and the crown tread portion 43 is located between the central tread portion 42 and the shoulder tread portion 41. The first lateral groove 11 includes a first groove segment 113 opposite to the center tread portion 42, a second groove segment 114 opposite to the crown tread portion 43, and a third groove segment 115 opposite to the shoulder tread portion 41. The first groove segment 113 is set at a first angle A1 with the circumference of the tire, and the first angle A1 satisfies: 25°≤A1≤40°. The second groove segment 114 is set at a second angle A2 with the circumference of the tire, and the second angle A2 satisfies: 40°≤A2≤50°. The third groove segment 115 is set at a third angle A3 with the circumference of the tire, and the third angle A3 satisfies: 65°≤A3≤75°. And / or, the second lateral groove 12 includes a fourth groove segment 121 opposite to the center tread portion 42, a fifth groove segment 122 opposite to the crown tread portion 43, and a sixth groove segment 123 opposite to the shoulder tread portion 41. The fourth groove segment 121 is set at a fourth angle A4 with the tire circumferential direction, and the fourth angle A4 satisfies: 25°≤A4≤40°. The fifth groove segment 122 is set at a fifth angle A5 with the tire circumferential direction, and the fifth angle A5 satisfies: 40°≤A5≤50°. The sixth groove segment 123 is set at a sixth angle A6 with the tire circumferential direction, and the sixth angle A6 satisfies: 65°≤A6≤75°. In this way, multiple second longitudinal grooves 22 divide the intermediate tread blocks into a central tread portion 42 and a crown tread portion 43, making the distribution of the tread blocks more reasonable. On the one hand, this can even out the deformation of the tread blocks, improving the tire's handling and braking performance; on the other hand, it can ensure the tire's straight-line driving stability and also ensure the tire's anti-skid performance when cornering and encountering lateral forces, ensuring the vehicle's driving stability and safety. At the same time, the arrangement of the first groove segment 113, the second groove segment 114, the third groove segment 115, the fourth groove segment 121, the fifth groove segment 122, and the sixth groove segment 123 limits the first lateral groove 11 and the second lateral groove 12 to be composed of multiple interconnected groove segments. This allows the first lateral groove 11 and the second lateral groove 12 to adapt to the tire's structural shape, which is beneficial for processing and also helps to provide multiple levels of drainage paths, making it more effective for the tire to expel snow and mud. At the same time, the above-mentioned arrangement also allows the first lateral groove 11 and the second lateral groove 12 to have different layout designs, ensuring the tire's aesthetics.Meanwhile, the arrangement of the first included angle A1, the second included angle A2, the third included angle A3, the fourth included angle A4, the fifth included angle A5, and the sixth included angle A6 makes the overall extension direction of the first lateral groove 11 and the second lateral groove 12 compatible with the center tread portion 42, the crown tread portion 43, and the shoulder tread portion 41. This makes the extension direction of the first lateral groove 11 and the second lateral groove 12 more suitable, which is more conducive to throwing out snow, water, and mud between the tire and the driving surface during the tire's rolling process. This further improves the tire's snow removal, water removal, and mud removal performance, and enhances the tire's handling and driving safety.

[0037] In this embodiment, the portion of the first groove segment 113 that passes through the center surface S forms the first sub-cross groove 111.

[0038] like Figure 1 As shown, a connecting groove 60 is provided on the tire sidewall, and the two ends of the connecting groove 60 are respectively connected to two adjacent transverse groove groups 1. In this way, the connecting groove 60 can help improve the tire's water drainage performance by connecting the two adjacent transverse groove groups 1, and balance the rigidity of the tread blocks on the sidewall, thus ensuring the rigidity of the sidewall.

[0039] like Figure 1 As shown, the tire sidewall is also provided with guide grooves 70, with both ends of the guide grooves 70 connected to the connecting grooves 60 and the edge of the sidewall, respectively. At least a portion of the guide grooves 70 are arranged in a zigzag shape. In this way, the guide grooves 70 can, on the one hand, assist in the drainage of water and snow flowing into the tire sidewall, improving the tire's snow removal, water drainage, and mud removal performance; on the other hand, they can balance the rigidity of the tire sidewall from multiple directions, improving the uniformity of the tire sidewall rigidity.

[0040] In this embodiment, the guide groove 70 has a "Z" shaped structure design.

[0041] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: The tire tread has a tread pattern, with multiple lateral groove groups arranged sequentially along the tire's circumference. Each lateral groove group includes a first lateral groove and a second lateral groove that are interconnected. At least a portion of the first lateral groove and the second lateral groove are located on opposite sides of the tire's center surface S, forming a herringbone structure. Longitudinal groove groups include multiple grooves spaced apart along the tire's width. These grooves are positioned between adjacent lateral groove groups, with their ends connected to the adjacent lateral groove groups. Specifically, along the tire's circumference, adjacent lateral groove groups include a first lateral groove group and a second lateral groove group. The first lateral groove of the first lateral groove group is connected to and adjacent to the first lateral groove of the second lateral groove group, and the second lateral groove of the first lateral groove group is adjacent to the first lateral groove of the second lateral groove group. This "V"-shaped arrangement of the first and second transverse grooves serves two purposes: First, it allows the tire tread blocks to better embed themselves into the ground, increasing friction between the tire and the ground, thus ensuring tire grip, preventing tire slippage, maintaining traction, and guaranteeing driving safety. Second, it effectively removes ice, snow, and wastewater from the tire tread, ensuring snow, water, and mud removal capabilities, maintaining wet-weather handling performance, and further enhancing driving safety. Simultaneously, the multiple longitudinal grooves, working in conjunction with the transverse grooves, expel ice, snow, and wastewater, further increasing friction between the tire and the ground and improving wet-weather handling and driving safety. Meanwhile, the connection between the first lateral groove of the first lateral groove group and the first lateral groove of the second lateral groove group in two adjacent lateral groove groups, as well as the arrangement of the second lateral groove of the second lateral groove group, can form a complete snow removal, water drainage, and mud removal network on the tread with the longitudinal groove group. This improves the tire's snow removal, water drainage, and mud removal performance, further enhances the tire's handling and driving safety, and thus solves the problem of low driving safety of existing tires on icy and snowy roads.
