Tread Wear
This grade measures the wear rate of the tyre when tested under controlled conditions. 100 represents the basic quality standard.
- More than 100 – Better
- 100 – Baseline
- Less than 100 – Poor
Tread wear grades are valid only for comparisons within a manufacturer’s product line – not between manufacturers.
Traction
Traction grades represent the tyre’s ability to stop in the wet. The grade is based upon straight line braking tests, not cornering ability.
- A – Best
- B – Intermediate
- C – Acceptable
Temperature
The temperature grades represent the tyre’s resistance to the generation of heat.
- A - Best
- B - Intermediate
- C - Acceptable
