What these grades mean in plain English
- Treadwear 680: this is a very high treadwear grade, the top end of the UTQG scale. Under UTQG a grade of 200 should wear twice as long as the grade-100 control tire on NHTSA's test course; real-world mileage varies with driving, rotation, alignment and climate.
- Traction A: A: second-highest wet-braking grade. Traction is straight-ahead wet braking only; it does not measure cornering or hydroplaning.
- Temperature A: A (highest): resisted heat build-up through the higher 575 rpm test stage.
- Ranked just above in Cooper: ENDEAVOR PLUS (H/V-rated) (median 680).
- Ranked just below in Cooper: Endeavor (median 680).
