The purpose of this wear testing was to determine the suitability of the ASTM-G78-15 standard traction tire as a control for treadwear test as specified in Federal Register March 7, 1973. It was evident that after 4,000 miles of testing that the ASTM tire used as a control was an extremely long wearing tire. The tire is relatively insensitive to minor route changes. An attempt to introduce major route changes resulted in shoulder separations and groove cracking.
