UNIFORM TIRE QUALITY GRADING-TREADWEAR (CITY TEST)

The development of a practical means of establishing relative passenger tire treadwear rates has been the basis of an ongoing study. The data from specific tests are used to grade tires in respect to treadwear in response to the criteria set forth by the National Traffic and Motor Vehicle Safety Act of 1966. Several efforts are being made to provide expeditious and practical, yet accurate, procedures by imposition of closely controlled and regulated wear-type maneuvers over a pre-selected test course. In the interest of universal application, this study provides for the design of such a course on readily available public thoroughfares.
