What these grades mean in plain English
- Treadwear 460: this is an above-average treadwear grade, typical of many touring and all-season 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 Tempra: R404 (median 540).
- Ranked just below in Tempra: R202 (median 270).

FAQ
What is the treadwear rating of the Tempra Mach 4 R302?
NHTSA's UTQG data lists treadwear grades from 420 to 500 (median 460) for the Tempra Mach 4 R302, from 18 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Tempra Mach 4 R302 treadwear grade high or low?
A grade of 460 is an above-average treadwear grade, typical of many touring and all-season tires. Compared with every line in the NHTSA data, the median is higher than 62% of lines (dataset median 420). Within Tempra it ranks #2 of 3.
What is the cost per mile of the Tempra Mach 4 R302?
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.
