AGOURA HILLS, Calif. (March 20, 2002)—The J.D. Power and Associates 2001 Heavy-Duty Truck Original Equipment Tire Report said truck owners gave high marks to Michelin tires and that Bridgestone tire owners reported a low incidence of problems.
Michelin received strong ratings from Class 8 customers in the three areas that comprise overall satisfaction: tire safety, wearability and tread life, and tire value. Bridgestone fared well, but below Michelin in the same attributes. Bridgestone customers report the fewest number of things wrong, in number of problems per 100 tires.
The report cites excessive or uneven tread wear and blowouts as the most frequently reported heavy-duty truck tire problems. It also measures sidewall separation, tread separation, tire out of round or unbalanced, and tire seal leaks as problem categories.
