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.
NHTSA records for Dimension IV ALL SEASON
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.

Cost-per-mile calculator
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 Dimension IV ALL SEASON?
NHTSA's UTQG data lists a single treadwear grade of 440 for the Dimension IV ALL SEASON, from 4 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.
Is the Dimension IV ALL SEASON 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 Dimension IV it ranks #1 of 1.
What is the cost per mile of the Dimension IV ALL SEASON?
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.
