What these grades mean in plain English
- Treadwear 200: 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 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 GT Radial: CHAMPIRO SX2 RS (median 220).

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 GT Radial CHAMPIRO SX2?
NHTSA's UTQG data lists treadwear grades from 200 to 260 (median 200) for the GT Radial CHAMPIRO SX2, from 7 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the GT Radial CHAMPIRO SX2 treadwear grade high or low?
A grade of 200 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 5% of lines (dataset median 420). Within GT Radial it ranks #29 of 29.
What is the cost per mile of the GT Radial CHAMPIRO SX2?
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.
