What these grades mean in plain English
- Treadwear 540: this is a high treadwear grade; the manufacturer rates this tire to wear slowly relative to the government control tire. 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 Americus: Touring CUV (median 560).
- Ranked just below in Americus: Sport HP (median 500).
NHTSA records for Americus A/T
Each row is one NHTSA record as filed by the manufacturer. Sizes are shown exactly as NHTSA lists them; entries such as “All sizes” apply a single grade to several sizes and cannot be matched to one specific size.

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 Americus A/T?
NHTSA's UTQG data lists a single treadwear grade of 540 for the Americus A/T, from 19 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Americus A/T treadwear grade high or low?
A grade of 540 is a high treadwear grade; the manufacturer rates this tire to wear slowly relative to the government control tire. Compared with every line in the NHTSA data, the median is higher than 80% of lines (dataset median 420). Within Americus it ranks #3 of 5.
What is the cost per mile of the Americus A/T?
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.
