In order to improve the wear resistance of complex pattern tire, the bionic design of tread pattern block was carried out on the 205/55R16 radial tire for passenger car. Firstly, the finite element model of tire with bionic pit structure on the surface of tread block was established, and the friction energy loss rate was selected as the evaluation index of tire wear resistance. The experimental scheme was designed by orthogonal experiment to study the influence of surface morphological parameters (pit diameter, pit depth and pit center distance) of bionic non-smooth pits on the friction energy loss rate. The results show that the pit diameter has the greatest effect on the friction energy loss rate, followed by pit depth, and pit center spacing has the least effect on the results. The friction energy loss rate of the bionic concave pattern tire designed according to the bionic principle is lower than that of the smooth pattern tire, which can improve the wear resistance of the tire.
