The traction grade assigned to this tire is based on

straight-ahead braking traction tests, and does not include

acceleration, cornering, hydroplaning or peak traction characteristics.

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.

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.

SERVICING YOUR TIRES

Checking the tire pressure

• Use an accurate tire pressure gauge.

• Check the tire pressure when tires are cold, after the vehicle has been

parked for at least one hour or has been driven less than 5 km (3 miles).

• Adjust tire pressure to recommended specifications found on the

Certification Label. Tire pressure information can also be found on the

Tire Information label located on the inside of the fuel filler door.

Improperly inflated tires can affect vehicle handling and can fail

suddenly, possibly resulting in loss of vehicle control, vehicle

rollover and/or personal injury.

Tire rotation

Because your vehicle’s tires perform different jobs, they often wear

differently. To make sure your tires wear evenly and last longer, rotate

them as indicated in the scheduled maintenance guide. If you notice that

the tires wear unevenly, have them checked.
