In this paper, the tread pattern directly determines the tire grounding performance. With the help of ABAQUS software and orthogonal test method, the influence of pattern structure parameters on tire performance is analyzed. It is found that the change of groove wall angle has a significant influence on tire grip and wear performance, and it is easy to aggravate the inherent contradiction between the two properties. Further analysis shows that the problem is mainly caused by the change of longitudinal stiffness of blocks. In order to solve this problem, the arch structure design method was used to optimize the shape of the transverse groove wall of the tire pattern. The results show that the arch structure design of the transverse groove wall can increase the longitudinal rigidity of the pattern block, reduce the deformation of the tire pattern during sliding and the peak ground pressure at the front end of the ground contact to a certain extent, and alleviates the inherent contradiction between tire grip and wear performance, and improves the two performances synergistically.
