Temperature A, B, C The temperaturegrades are A (the highest), B, and C, representing the tire's resistance to the generation heat and its ability to dissipate heat of when tested under controlledconditions on aspecified indoor laboratory test wheel. Sustained high temperature can cause the material the tire of to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.The grade C corresponds to alevel of performance which all passenger car tiresmust meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for tire is established for a tire that this is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separatelyor in combination, can cause heat buildup and possible tire failure. These grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motorsperformance standards andhave been approved for use on GeneralMotors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades. - 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. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road,your wheels may need to be rebalanced. 6-48
