The purpose of the wear testing was (a) to confirm the proposed Uniform Tire Quality Grading procedure, as published in the Federal Register on March 7, 1973, using the 7.75-14 (2 ply rayon) size as the control tire; (b) to confirm the suitability of using a single size control tire (7.75-14) as the treadwear reference base for a range of sizes (i.e. D78-14, F78-14, H78-14, etc.); (c) to determine whether similar treadwear ratings are obtained when specific size tire (D78-14) is tested at different inflation pressures using respective Tire and Rim loads (i.e. 24 lbs inflation - 1120 lbs load vs 32 lbs inflation - 1320 lbs load); (d) to develop a treadwear route where the control tire will be worn 75 plus or minus 10% after 16000 route miles.
