A Laboratory Technique for Evaluating Tire Tread Wear

A laboratory technique has been developed for producing road-like tire tread wear and obtaining quantitative results. The tire is operated on a flat-roadway test machine and subjected to a schedule of applied lateral and longitudinal forces to promote wear. Wear measurements are made using sensitive, electromechanical wear sensors. Some typical test data are shown. Operational experiences are cited and recommendations for technique improvement are made.
