This study focuses on the influence of pattern block stiffness on tire wear resistance. The Yeoh model was selected to describe the constitutive relationship of the pattern block rubber material, and the parameters were obtained by uniaxial tensile test of the tire tread rubber sample. The common geometric parameters of tread pattern were selected as the optimal objects, including transverse groove depth, transverse groove wall angle and longitudinal groove wall angle. Numerical experiments were designed by orthogonal test method. The finite element software Abaqus was used to simulate the pattern block, and the ground pressure skewness value was selected to evaluate the wear resistance of the pattern block. The numerical test results showed that the transverse groove wall angle had a great influence on the ground pressure distribution. Moreover, the wear resistance of the pattern block increases with the increase of the longitudinal stiffness. Finally, it was concluded that the longitudinal stiffness of the pattern block had a great influence on the wear resistance during the slip. Therefore, reasonable design of the pattern block could appropriately increase longitudinal stiffness, which could improve the wear resistance of the tire.
