This information is provided in compliance with the requirements of the National High-way Traffic Safety Administration, Depart- ment of Transportation. It provides the purchasers and/or prospective purchaserswith information on reporting safety defects. DOT quality grades - All passenger vehicle tires must conform to Federal Safety Require-ments in addition to these grades. The spe- cific grade rating in each grade category is shown on the side wall of the tires on yourvehicle. The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tiregraded 150 would wear one and one-half (11/2) times as well on the government course
as a tire graded 100. The relative performance of tires depends upon the actual conditions of
their use, however, and may depart signifi- cantly from the norm due to variations in driving habits, service practices and differ- ences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Those grades representthe tire’s ability to stop on wet pavement asmeasured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poortraction performance. The temperature grades are A (the highest), B and C, representing the tire’s resistance to thegeneration of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corre- sponds to a level of performance which allpassenger car tires must meet under the Fed- eral Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels ofperformance on the laboratory test wheel than the minimum required by law.

Traction AA, A, B, C
WA R N I N G The traction grade assigned to the tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak tractioncharacteristics.
Temperature A, B, C
WA R N I N G The temperature grade for the tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive load-ing, either separately or in combination, can cause heat buildup and possible tire failure.
