12. Treadwear, Traction and Temperature Grades

• Treadwear: The treadwear grade is a comparative rating based on the

wear rate of the tire when tested under controlled conditions on a

specified government test course. For example, a tire graded 150

would wear one and one-half (1

⁄

) times as well on the government

course as a tire graded 100.

• Traction: The traction grades, from highest to lowest are AA, A, B,

and C. The grades represent the tire’s ability to stop on wet pavement

as measured under controlled conditions on specified government test

surfaces of asphalt and concrete. A tire marked C may have poor

traction performance.

• 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.

13. Maximum Permissible Inflation Pressure: Indicates the tire

manufacturers’ maximum permissible pressure and/or the pressure at

which the maximum load can be carried by the tire. This pressure is

normally higher than the manufacturer’s recommended cold inflation

pressure which can be found on either the tire label or certification label

which is located on the B-Pillar or the edge of the driver’s door. The cold

inflation pressure should never be set lower than the recommended

pressure on the vehicle label.

The tire suppliers may have additional markings, notes or warnings such

as standard load, radial tubeless, etc.
