What these grades mean in plain English
- Treadwear 280: this is a lower-than-typical treadwear grade, common on sport and high-performance 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 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 Dunlop: SP SPORT FASTRESPONSE (median 280).
- Ranked just below in Dunlop: SP SPORT MAXX 050 DSST (median 280).

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 Dunlop SP SPORT MAXX 050?
NHTSA's UTQG data lists treadwear grades from 240 to 300 (median 280) for the Dunlop SP SPORT MAXX 050, from 10 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Dunlop SP SPORT MAXX 050 treadwear grade high or low?
A grade of 280 is a lower-than-typical treadwear grade, common on sport and high-performance tires. Compared with every line in the NHTSA data, the median is higher than 15% of lines (dataset median 420). Within Dunlop it ranks #106 of 154.
What is the cost per mile of the Dunlop SP SPORT MAXX 050?
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.
