Temperature – A, B, CThe temperature grades are A (the highest), B, and C,representing the tire’s resistance to the generationof heat and its ability to dissipate heat when testedunder controlled conditions on a specified indoorlaboratory test wheel. Sustained high temperaturecan cause the material of the tire to degenerate andreduce tire life, and excessive temperature can lead tosudden tire failure. The grade C corresponds to alevel of performance which all passenger car tires mustmeet under the Federal Motor Vehicle Safety StandardNo. 109. Grades B and A represent higher levels ofperformance on the laboratory test wheel than theminimum required by law.Warning: The temperature grade for this tire isestablished for a tire that is properly inflated and notoverloaded. Excessive speed, underinflation, orexcessive loading, either separately or in combination,can cause heat buildup and possible tire failure.Wheel Alignment and Tire BalanceThe wheels on your vehicle were aligned and balancedcarefully at the factory to give you the longest tire lifeand best overall performance.Scheduled wheel alignment and wheel balancing arenot needed. However, if you notice unusual tire wear oryour vehicle pulling one way or the other, the alignmentmay need to be reset. If you notice your vehiclevibrating when driving on a smooth road, your wheelsmay need to be rebalanced.Wheel ReplacementReplace any wheel that is bent, cracked or badly rustedor corroded. If wheel nuts keep coming loose, thewheel, wheel bolts and wheel nuts should be replaced.If the wheel leaks air, replace it (except somealuminum wheels, which can sometimes be repaired).See your dealer if any of these conditions exist.Your dealer will know the kind of wheel you need.5-75
