TIRE-RATING SYSTEM, RELIABILITY DISPUTED, IS SUSPENDED BY U.S.
The Reagan Administration today suspended a grading standard that provides consumers with information for comparing the durability of tires. The Administration and most major manufacturers of replacement tires, a $6 billion industry in 1982, contend that the tread-wear grading system is unscientific and that consumers may be misled by it. The system covers 93 brands of automobile tires in 2,500 sizes and styles. Raymond A. Peck, Administrator of the National Highway Traffic Safety Administration, said today: ''We just cannot reliably tell whether a higher-graded tire will wear better than a lower-graded tire. The standard is not only failing in its primary purpose of informing consumers, it is misleading some of them.''
