Features & Benefits
- Treadwear: The treadwear grade is a comparative rating based on the wear rate of the tyre when tested under controlled conditions on a specified government test course. For example, a tyre graded 400 the tread would last two times longer than graded 200.
- Traction: The traction grades, from highest to lowest, are AA, A, B and C. These grades represent the tyre's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. tyres marked AA has excellent traction performance and tyres marked C may have poor traction performance.
- Temperature: The temperature grades are A (highest), B and C, representing the tyre's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions. Sustained high temperature can cause the material of the tyre to de- generate and reduce tyre life, and excess temperature can lead to sudden tyre failure. The grade C corresponds to a level of performance which all passenger car tyres must meet under the Federal Motor Vehicle Safety Standard # 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
