In summer, it rains a lot, the tire needs to drain quickly, maintain wet ground grip, prevent water sliding phenomenon, if the tire wet ground performance is insufficient, it may lead to vehicle skidding and out of control when driving in rainy days, increase driving risk. In winter, the tire needs to maintain enough softness and elasticity, to ensure that there is still good grip on the ice and snow road surface, otherwise it will lead to tire hardening, grip decline, and increase driving risk. In addition, the winter ice and snow road surface needs the tire to provide excellent braking and handling performance, to ensure that the vehicle is stable driving under ice and snow conditions, if the tire ice and snow performance is poor, it may lead to vehicle skidding and out of control on the ice and snow road surface, difficult to effectively brake, increase driving risk. Winter snow also needs the tire to provide good traction, to ensure that the vehicle can start, accelerate and climb smoothly, otherwise it may lead to the vehicle sinking in the snow, unable to drive, and affect driving safety.

[0023] On the basis of example 1, as Figure 1 , 3As shown, the sidewall of the longitudinal groove three 6 near the shoulder block 1 is stepped, which can better disperse the stress received by the tire during driving, reduce the wear caused by excessive local pressure, and prolong the service life of the tire. Moreover, the stepped groove wall design helps to quickly discharge water, mud and other debris in the longitudinal groove three 6, reduces the water film effect, and improves the grip of the tire on wet road surface. In addition, on complex road surface, the vehicle is prone to side slip, and the stepped groove wall design of the embodiment can provide stronger lateral grip, effectively prevent the tire from side slipping when turning or avoiding obstacles, so that the vehicle is more stable during driving, and the vehicle sway caused by uneven road surface or sudden situation is reduced.
[0024] Example 3
[0025] Based on example 1, as shown in Figures 1-2 , the bottom of the transverse groove two 7 is provided with a plurality of reinforcing ribs 9. On the rough road, the tire is easy to be pierced by sharp objects, and the reinforcing ribs 9 can effectively disperse the impact force of these sharp objects on the tire, reducing the possibility of puncture. And when encountering road obstacles, the reinforcing ribs 9 can provide additional support, reduce damage when the tire directly collides with the obstacle, and can improve the passability and safety of the tire.
