This study focus on the modeling methods of radial tires with different tread patterns and conducts simulation analysis. Considering the material nonlinearity and geometric nonlinearity of tire, Hypermesh and ABAQUS finite element software were used to study the modeling method. Under the standard pressure, two tire models are simulated under static load. The vertical stress distribution of contact patch and the relationship between load and subsidence were obtained. Moreover, the influence of tread patterns and load on contact patch were analyzed. The results show that the relationship between load and subsidence is approximately a linear function. With the load increases, the peak stress location shifts from the center of crown to the shoulders. The peak stress of tires with complex tread patterns are greater than that with only longitudinal grooves. With the increase of the load, the grounding area of both types of tread patterns tires gradually increases, and the grounding area of complex tread patterns tire is small than that of longitudinal groove tire. The research results provide a finite element simulation reference for the further optimization of tire design.
