In this study. as an efficient method for measuring the frictional energy on the contact patch of an automobile tires, paint wear method is described. It comprises applying a single layer of paint to tread surface by spraying, running the tires on a vehicle for a short distance, assessing the wear rate by measuring the intensities of reflecting lights at various locations, and comparing them with original values. This method permits the wear rate to be quantitatively evaluated with a very high resolution under well-controlled test conditions.<br/> A typical example is provided to show wear distribution across shoulder to shoulder of passenger car tires. Tread wear patterns produced by different toe-in angle have been analyzed through the range of tread wear patterns. Application of this method makes studies of the effects of wheel alignment and tire on uneven wear possible.<br/>
