What these grades mean in plain English
- Treadwear 540: 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 B: B: middle 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 Michelin: Primacy LTX (median 540).
- Ranked just below in Michelin: Energy LX4 (median 500).

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 Michelin Primacy Tour A/S?
NHTSA's UTQG data lists a single treadwear grade of 540 for the Michelin Primacy Tour A/S, from 14 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Michelin Primacy Tour A/S treadwear grade high or low?
A grade of 540 is a high treadwear grade; the manufacturer rates this tire to wear slowly relative to the government control tire. Compared with every line in the NHTSA data, the median is higher than 80% of lines (dataset median 420). Within Michelin it ranks #21 of 57.
What is the cost per mile of the Michelin Primacy Tour A/S?
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.
