DETERMINATION OF 100% TIRE TREAD LOSS BY WEIGHT

The program was conducted as a supplement to a major effort, "An Investigation of A Low-Variability Tire Treadwear Test Procedure and of Treadwear Adjustment for Ambient Temperature". That program was conducted during 1984 and involved the refinement of a procedure to establish the rate of tire wear by sequential measurements of the tire weight at regular intervals of mileage. It was necessary that a means of determining "100% worn" by weight be established for use in computing projected miles to worn out when wear rate in grams/1000 miles had been calculated. Tires were buffed (rasped) to remove the tread using available commercial retread processing equipment. The details of the process are discussed. Illustrations of the results are presented. Data comparing the dimensional and weight techniques are shown.
