What these grades mean in plain English
- Treadwear 320: this is a moderate treadwear grade, near the middle of NHTSA-rated 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 AA: AA (highest): best wet-pavement straight-line braking grade on the government test surfaces. 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.

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).

FAQ
What is the treadwear rating of the Wards ADVAN S.T.?
NHTSA's UTQG data lists a single treadwear grade of 320 for the Wards ADVAN S.T., from 4 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Wards ADVAN S.T. treadwear grade high or low?
A grade of 320 is a moderate treadwear grade, near the middle of NHTSA-rated tires. Compared with every line in the NHTSA data, the median is higher than 26% of lines (dataset median 420). Within Wards it ranks #1 of 1.
What is the cost per mile of the Wards ADVAN S.T.?
We do not have a licensed price or warranty-mileage feed yet, so we do not state a cost per mile. Use the formula cost per 1,000 miles = price per set ÷ (expected miles ÷ 1,000) with your own quote and mileage expectation, or the calculator on this page.
