RESEARCH FOR A UNIFORM QUALITY GRADING SYSTEM FOR TIRES. IV. TREAD WEAR

THE RESEARCH HAD AS ITS OBJECTIVE THE DEVELOPMENT OF A TEST PROCEDURE FOR RATING TIRES FOR TREAD WEAR. THE RESULTS OF PRELIMINARY EXPERIMENTS ON ROADS OF DIFFERENT COMPOSITION AND SEVERITY ARE DISCUSSED. THE AUTHORS CONCLUDE THAT THE COURSE ON WHICH TIRES ARE TO BE RATED SHOULD INCLUDE SEVERAL DIFFERENT PAVEMENTS AND A VARIETY OF MANEUVERS OF UNEQUAL SEVERITY. TWO COURSES, ONE NEAR BRYAN, TEXAS, AND THE OTHER NEAR SAN ANTONIO, TEXAS, WERE DESIGNED ON THIS PRINCIPLE. EIGHTEEN BRANDS OF TIRES INCLUDING BIAS, RADIAL, AND G78 BELTED BIAS TIRES WERE RUN ON EACH COURSE. THE TIRES RANKED IN ORDER OF DECREASING PROJECTED MILEAGE ON EACH COURSE WERE HIGHLY CORRELATED, ALTHOUGH THE MILEAGES WERE NOT EQUAL. /AUTHOR/
