UNIFORM TIRE QUALITY GRADING TREADWEAR COURSE MONITORING-IV
A 400-mile road test course over public highways in the vicinity of San Angelo, Texas has been used to evaluate candidate Course Monitoring Tires for the treadwear requirement of the Uniform Tire Grading Program. This portion of the program is designated Phase IV and provides for (a) continued evaluation of certain previously selected CMT's, and (b) the monitoring of the test course for usage during the period of June 1976 through September 1977. Phase IV consists of 99 test series of 6400 miles each. The testing was conducted in 33 successive convoys of three cars each. Data collected upon measurement of the individual tires at 800-mile increments were provided to the manager of the UTQG Test Center at San Angelo. The resultant tread wear rates for each tire and the related projected mileage estimates are presented in this report with details of the test conduct and processes.
