Tread Wear
- More Than 100 - Better
- 100 - Baseline
- Less Than 100 - Poorer
The tread wear grade is a comparative rating based on the
wear rate of the tyre when tested under controlled conditions on a
specified government test track. A tyre graded 200 would wear twice as
long on the government test track as one graded 100. Your actual tyre
mileage depends upon the conditions of their use and may vary due to
driving habits, service practices, differences in road characteristics
and climate. Note: Tread wear grades are valid only for comparisons
within a manufacturer's product line. They are not valid for comparisons
between manufacturers.
Traction
- A - Best
- B - Intermediate
- C - Acceptable
Traction 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. The Traction grade is
based upon "straight ahead" braking tests; it does not indicate
cornering ability.
Temperature
- A - Best
- B - Intermediate
- C - Acceptable
The temperature grades represent the tyre's resistance to
the generation of heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high temperatures can
cause the materials of the tyre to degenerate and thus reduce tyre life.
Excessive temperatures can lead to tyre failure.
