Moreover, the opening angles of different V-shaped structures also ensure the handling stability of the tire.

[0006] The utility model discloses a tire tread, which is provided with a middle longitudinal groove, side tread blocks, and shoulder longitudinal grooves on the tread surface from inside to outside in sequence, and further includes:

[0007] A pair of side transverse grooves and a pair of side steel sheet grooves, which are symmetrically arranged on the side tread blocks on both sides of the middle longitudinal groove, and each side transverse groove and each side steel sheet groove are composed of inner and outer sections connected to form a V-shaped structure, and the opening angles of the two V-shaped structures are different;

[0008] The outer section of the side transverse groove is connected to the shoulder longitudinal groove, and the inner section of the side transverse groove is located within the side tread block; the inner section of the side steel sheet groove is connected to the middle longitudinal groove, and the outer section of the side steel sheet groove is connected to the side transverse groove.

Those of ordinary skill in the art explicitly and implicitly understand that the embodiments described in the present utility model can be combined with other embodiments without conflict.

[0031] As Figure 1 shown, a tire tread is provided with a central longitudinal groove 1, side tread blocks 2, shoulder longitudinal grooves 3, and shoulder tread blocks 4 arranged in sequence from the inside to the outside on the tread surface; among them, the central longitudinal groove 1 and the shoulder longitudinal groove 3 form three wide and deep longitudinal main grooves, enabling a large amount of water to quickly pass through when the van is driving in the rain, reducing the formation of the water film, thereby reducing the risk of hydroplaning. At the same time, the wide and deep main longitudinal grooves help to increase the contact area between the tire and the ground, better "grip" the ground, and provide stronger grip. Specifically, it further includes:

[0032] A pair of side transverse grooves 5 and a pair of side steel sheet grooves 6 are symmetrically arranged on the side tread blocks 2 on both sides of the central longitudinal groove 1, and each side transverse groove 5 and each side steel sheet groove 6 are composed of inner and outer segments connected to form a V-shaped structure, and the opening angles are different; adopting a symmetric pattern design makes the performance of the tire more balanced in all directions, ensuring the safety of the van during the transportation of goods and reducing vehicle shaking and cargo damage caused by unstable tire performance; at the same time, the different opening angles of the V-shaped structures of the side transverse grooves and the side steel sheets also ensure the controllability of the tire in all-round motion states.

[0033] The outer section of the lateral transverse groove 5 is connected to the shoulder longitudinal groove 3, and the inner section of the lateral transverse groove 5 is located within the lateral tread block 2; the inner section of the lateral steel sheet groove 6 is connected to the middle longitudinal groove 1, and the outer section of the lateral steel sheet groove 6 is connected to the lateral transverse groove 5. The lateral steel sheet groove 6 can conduct a part of the heat, while the lateral transverse groove 5 promotes the air circulation, jointly improving the heat dissipation performance of the tire, reducing the risk of tire damage due to overheating, and extending the service life of the tire.

[0034] In some embodiments, the inner sections of the lateral transverse grooves 5 located on both sides of the middle longitudinal groove 1 and the inner sections of the lateral steel sheet grooves 6 are arranged collinearly. Specifically, as Figure 1 shown, the middle part thereof forms a structure similar to a parallelogram. Of course, a structure with upper and lower dislocation can also be adopted for setting.

[0035] In some embodiments, the inner section of the lateral transverse groove 5 has a structure with an increasing diameter from the inside to the outside. The structure with an increasing diameter can effectively improve its heat dissipation ability. Compared with the setting of the same width, it can avoid too much reduction in the rigidity strength of its tread block and ensure the rigidity strength.

[0036] In some embodiments, the intersection of the lateral steel sheet groove 6 and the lateral transverse groove 5 is located at the outer section of the lateral transverse groove 5. Specifically, the inner ends of the lateral transverse groove 5 and the upper side of the inner end of the lateral steel sheet groove 6 ( Figure 2 ) are arranged in parallel, and the intersection is located at the 1 / 2 position of the outer section length at the inflection point of the outer end of the lateral transverse groove 5. At the same time, the distance A from the inner section of the lateral transverse groove 5 to the middle longitudinal groove 1 is equal to the distance B from the inflection point of the inner end of the lateral steel sheet groove 6 to the middle longitudinal groove 1. Through the above setting method, the overall rigidity strength, heat dissipation performance, and handling performance of its tread block are made to be in an as balanced state as possible.

[0037] In some embodiments, it further includes:

[0038] A pair of shoulder first transverse grooves 7, symmetrically arranged on the shoulder tread blocks 4 outside the shoulder longitudinal groove 3;

[0039] The inner ends of the shoulder first transverse grooves 7 are connected to the shoulder longitudinal groove 3 and form an overall V-shaped structure with the outer section of the lateral transverse groove 5, and the width of the inner ends of the shoulder first transverse grooves 7 is smaller than the width at the connection of the outer section of the lateral transverse groove 5 and the shoulder longitudinal groove 3. The V-shaped structure improves the handling performance of the tire. At the same time, the inconsistency in width reduces the transmission of noise to improve its sound insulation effect and provide better comfort for the driver and passengers.

[0040] In some embodiments, the shoulder first transverse groove 7 is provided with an enlarged diameter portion at the extension from its inner end to the outer end. Through the enlarged diameter portion, the rapid drainage of water can be realized and its drainage ability can be improved.

[0041] In some embodiments, it further includes:

[0042] The third transverse groove 10 of the shoulder is communicatively provided at the end of the first transverse groove 7 of the shoulder;

[0043] The second transverse groove 8 of the shoulder is provided on one side of the first transverse groove 7 of the shoulder and has an inconsistent inclination angle with the third transverse groove 10 of the shoulder;

[0044] The steel sheet groove 9 of the shoulder is communicatively provided between the third transverse groove 10 and the second transverse groove 8 of the shoulder.

[0045] Specifically, the second transverse groove 8 of the shoulder, the steel sheet groove 9 of the shoulder, and the third transverse groove 10 of the shoulder as a whole form a W-shaped structure. By adjusting the rigidity strength of the tread blocks on the tire shoulder through the structural settings of the second transverse groove 8 of the shoulder, the steel sheet groove 9 of the shoulder, and the third transverse groove 10 of the shoulder, not only can the stable shape and handling performance be maintained under heavy loads through the above-mentioned multi-folded structure design method. At the same time, it adds a very personalized and recognizable appearance. This unique design can make the vehicle stand out instantly and show a distinctive style.
