The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from thenorm due to variations in drivinghabits, service practices anddifferences in roadcharacteristics and climate.TractionThe traction grades, fromhighest to lowest, are AA, A, B,and C. Those grades representthe tire's ability to stop on wetpavement as measured undercontrolled conditions onspecified government testsurfaces of asphalt andconcrete. A tire marked C mayhave poor traction performance.Warning: The traction gradeassigned to this tire is based onstraight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning, or peak tractioncharacteristics.TemperatureThe temperature grades are A(the highest), B, and C,representing the tire's resistanceto the generation of heat and itsability to dissipate heat whentested under controlledconditions on a specified indoorlaboratory test wheel. Sustainedhigh temperature can cause thematerial of the tire to degenerateand reduce tire life, andexcessive temperature can leadto sudden tire failure. The gradeC corresponds to a level ofperformance which allpassenger car tires must meetunder the Federal Motor SafetyStandard No. 109. Grades B andA represent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law. Warning: Thetemperature grade for this tire isestablished for a tire that isproperly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.Wheel Alignment and TireBalanceThe tires and wheels were alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingare not necessary on a regularbasis. Consider an alignment checkif there is unusual tire wear or thevehicle is significantly pulling to oneside or the other. Some slight pull tothe left or right, depending on thecrown of the road and/or other road
