What these grades mean in plain English
- Treadwear 500: this is a high treadwear grade; the manufacturer rates this tire to wear slowly relative to the government control tire. 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 JK Tyre: ELANZO TOURING + (median 600).
- Ranked just below in JK Tyre: UX TOURING (median 480).

Cost-per-mile calculator
Price and mileage data are pending a licensed feed, so nothing is pre-filled. Enter your own quote and your own mileage expectation (for example the maker's treadwear warranty from the tire's paperwork). Formula: cost per 1,000 miles = price per set ÷ (expected miles ÷ 1,000).
