Temperature – A, B, C

The temperature grades are A (the highest), B, and C,

representing the tire’s resistance to the generation

of heat and its ability to dissipate heat when tested

under controlled conditions on a speciﬁed indoor

laboratory test wheel. Sustained high 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 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 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 tires and wheels on your vehicle were aligned

and balanced carefully at the factory to give you

the longest tire life and best overall performance.

Adjustments to wheel alignment and tire balancing

will not be necessary on a regular basis. However,

if you notice unusual tire wear or your vehicle pulling

to one side or the other, the alignment may need to

be checked. If you notice your vehicle vibrating when

driving on a smooth road, your tires and wheels

may need to be rebalanced. See your dealer for

proper diagnosis.
