What these grades mean in plain English
- Treadwear 440: 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 B: B: passed the 500 rpm stage but not the 575 rpm stage.
- Ranked just above in Big O: SXP G/T 60/65/70 series (median 440).
- Ranked just below in Big O: SUN VALLEY 70 SR (median 420).

FAQ
What is the treadwear rating of the Big O SXP SUPER SPORT?
NHTSA's UTQG data lists a single treadwear grade of 440 for the Big O SXP SUPER SPORT, from 20 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Big O SXP SUPER SPORT treadwear grade high or low?
A grade of 440 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 54% of lines (dataset median 420). Within Big O it ranks #28 of 50.
What is the cost per mile of the Big O SXP SUPER SPORT?
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.
