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 Michelin: Pilot Sport A/S 3+ (median 500).
- Ranked just below in Michelin: Primacy MXV4 (median 500).

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 MXM4?
NHTSA's UTQG data lists treadwear grades from 420 to 500 (median 500) for the Michelin Primacy MXM4, from 27 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 MXM4 treadwear grade high or low?
A grade of 500 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 68% of lines (dataset median 420). Within Michelin it ranks #25 of 57.
What is the cost per mile of the Michelin Primacy MXM4?
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.
