INVESTIGATION OF A LOW-VARIABILITY TIRE TREADWEAR TEST PROCEDURE AND OF TREADWEAR ADJUSTMENT FOR AMBIENT TEMPERATURE. VOLUME 1. THE TEST PROCEDURES, STATISTICAL ANALYSES AND THE FINDINGS

The program was conducted to evalaute the variation in tire treadwear rates as experienced on identical vehicles during the various environmental exposure conditions of the winter, spring, and summer seasons. Tread loss was measured by determining the periodic loss in tread-groove depth and in total tire weight. Special investigations of (1) the effect of different drivers on treadwear results and (2) a means of determing projected mileage by using tire weight loss rates. The report contains a statistical analysis of the wear rates both in mils and grams per 1000 miles as they relate to the vehicle, season, environmental condition, driver, and how eight test sets each of four different manufacturer groups (total of 32 test sets) are variable within themselves.
