Tire shoulder wear and corresponding changes in tire cornering capability must be considered if meaningful, reproducible vehicle handling tests are to be developed. Up to now the problem has been partially solved by vehicle prewearing of tires which may result in unrealistic shoulder wear and vehicle handling capabilities believed to be unrepresentative of their 'real-world' counterparts. The main objective of the study was to develop a workable means, either in the form of new procedures for tire break-in or modifications to present procedures, number of tests involving tires from the three construction classes: bias ply, bias belted and radial. Two test vehicles and different break-in procedures and prewear states were considered. A statistical evaluation of the data was performed.
