Abstract: Due to plex characteristics of tire wear, as a general rule, it considers the
uniform distribution of contact pressure between the road and the tire as the criterion of tire wear. By
minimizing the difference between maximum contact pressure and the minimum contact pressure, the
skew estimated value of contact pressure and contact area, the uniform distribution of contact
pressure is achieved. The main parameters of tire structure include the followed four terms: the
width of belt, the value of h, the thickness of tire shoulder,the anti-packets height of carcass cord.
The morph function in HyperMesh is used to create the regional domains and handles on the tire
finite element model. In this paper, series heavy tire is used to analysis and the optimized ti
