What these grades mean in plain English
- Treadwear 280: this is a lower-than-typical treadwear grade, common on sport and high-performance tires. 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 Hankook: Z FIT EQ (median 280).
- Ranked just below in Hankook: veNtus Prime 2 A (OE) (median 280).
