Taking 205 / 55R16 radial tire as the research object, the model was established by using Hypermesh and ABAQUS finite element analysis software, and the correctness of the model was verified by the ground pressure test. The tire crown arc was designed with arc width b, arc height h and bionic structure to explore the influence of the tire crown arc on the tire grounding performance. The results show that with the increase of the tire crown arc width, the tire grip and wear performance are improved, and the ground mark is improved; With the increase of the crown arc height, the tire grip and wear performance decreased. The bionic tire crown arc structure design can cooperate to improve the grip and wear performance to a certain extent. The effect of the crown arc structure on the shoulder durability is small, about 3%.
