Tire wear is a very complicated phenomenon that is influenced by various\nfactors such as tire material, structure, vehicle and road conditions. In order\nto evaluate tire wear, a method for measuring tire wear using the intensity of\nreflected light was presented [1]. It comprises applying a single layer of reflected\npaint to a tread surface by spraying, and then measuring the intensity\nof light reflected from a matrix of blocks on the unworn tire. In this paper, a\nnumerical technique for predicting the uneven wear of passenger car tire is\npresented. The uneven tire wear produced in wheel alignment condition with\nvehicle speed, camber angle, and toe angle is predicted by the frictional dynamic\nrolling analysis of 3D patterned tire model. The proposed numerical\ntechnique is illustrated through the method of paint testing the wear on the\ntread surface of a tire.
