WARNING: 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. 139. 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.

TIRES

Tires are designed to give many thousands of miles of service, but they

must be maintained in order to get the maximum benefit from them.

Glossary of tire terminology

• Tire label: A label showing the OE (Original Equipment) tire sizes,

recommended inflation pressure and the maximum weight the vehicle

can carry.

• Tire Identification Number (TIN): A number on the sidewall of

each tire providing information about the tire brand and

manufacturing plant, tire size and date of manufacture. Also referred

to as DOT code.

• Inflation pressure: A measure of the amount of air in a tire.

• Standard load: A class of P-metric or Metric tires designed to carry a

maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing

the inflation pressure beyond this pressure will not increase the tire’s

load carrying capability.

• Extra load: A class of P-metric or Metric tires designed to carry a

heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].
