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

Summary
Tire wear is a complex phenomenon that is affected by tire materials, structures, vehicle dynamics, and road conditions [2]-[7]. Theoretical models have been developed for tire wear and vibration. Theoretical models are helpful in understanding numerical results with physical mechanisms which are responsible for the generation of tire wear and their behavior at different values of tire parameters. Chung and Lee [1] presented a method of testing uneven tire wear. It comprises applying a single layer of reflective paint to a tread surface by spraying, and measuring the intensity of light reflected from a matrix of blocks on the unworn tire. We started developing the method for measuring tire wear using intensity of reflected light using a finite element analysis. The proposed numerical technique is illustrated through the method of paint testing the wear on the tread surface of a tire
