Temperature:
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 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.
5.5.2 Tire Pressure
Maintain tire pressure of 35 psi (241 kPa)
– front; and 35 psi (241 kPa) – rear. Check tire pressure each
time you fill up with fuel.
5.5.3 Tire Rotation
To equalize tire wear, tires may be rotated. If there is unusual wear on the tire tread do not rotate until
the cause of unusual or uneven tire wear is determined and corrected.
Front and rear tires perform different jobs and can wear differently depending on the type of the vehicle
and driving habits. To equalize wear and extend tire life, rotate tires every 10,000 miles or 320 hours.
