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.Temperature – A, B, CThe temperature grades areA (the highest), B, and C,representing the tire's resistanceto the generation of heat andits ability to dissipate heatwhen tested under controlledconditions on a specified indoorlaboratory test wheel. Sustainedhigh temperature can cause thematerial of the tire to degenerateand reduce tire life, andexcessive temperature canlead to sudden tire failure. Thegrade C corresponds to a levelof performance 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 on the vehiclewere aligned and balanced carefullyat the factory to give the longest tirelife and best overall performance.Adjustments to wheel alignment andtire balancing will not be necessaryon a regular basis. However, if thereis unusual tire wear or the vehiclepulls to one side or the other, thealignment should be checked. If thevehicle vibrates when driving on asmooth road, the tires and wheelsmight need to be rebalanced. Seeyour dealer for proper diagnosis.Ofrecido por www.electromanuales.com
