What these grades mean in plain English
- Treadwear 650: this is a very high treadwear grade, the top end of the UTQG scale. 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 Bridgestone: DUELER H/L ALENZA PLUS "W" Spd Rtd (median 670).
- Ranked just below in Bridgestone: Dueler A/T Ascent (median 640).

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).

A grade of 650 is a very high treadwear grade, the top end of the UTQG scale. Compared with every line in the NHTSA data, the median is higher than 93% of lines (dataset median 420). Within Bridgestone it ranks #12 of 209.
What is the cost per mile of the Bridgestone ECOPIA H/L 422 PLUS?
