Temperature A, B, C The temperature grades are A (the highest), B, and C, representing the tire'sresistance to the generation of heat and its ability dissipate heat when tested under to controlled conditions on a specified indoor laboratory test wheel. Sustainedhigh 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 corresponds to a level of performance which all passenger car tires must meet under the No. Federal Motor Vehicle Safety Standard 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required law. by Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. - Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance.
