ABSTRACT - Studies of tire wear have been rarely conducted on wear progress but just wear of tires. The physical wear model has been developed to clarify the mechanism of wear progress and showed qualitative agreement with the observation where the kernel of irregular wear is initiated due to lateral stress and then the wear is accelerated due to longitudinal stress in tires. To improve irregular wear, both of maximum wear energy and step of irregular wear should be decreased. For example, ways for improvement of irregular wear are to increase the Young's modulus of tread rubber or increase the crown radius to decrease the radius between tire and shoulder
