What these grades mean in plain English
- Treadwear 800: 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 B: B: passed the 500 rpm stage but not the 575 rpm stage.
- Ranked just below in Bridgestone: DUELER H/L ALENZA PLUS "H" & "V" Spd Rtd (median 800).

FAQ
What is the treadwear rating of the Bridgestone Alenza AS Ultra?
NHTSA's UTQG data lists a single treadwear grade of 800 for the Bridgestone Alenza AS Ultra, 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 Bridgestone Alenza AS Ultra treadwear grade high or low?
A grade of 800 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 99.0% of lines (dataset median 420). Within Bridgestone it ranks #1 of 209.
What is the cost per mile of the Bridgestone Alenza AS Ultra?
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.
