UTQG grades aren’t absolute for cross-brand comparisons. They’re useful when comparing tires within the same brand.

"Well, these often-misunderstood "grades" do provide some information for consumers, but unfortunately they're not as useful as originally intended when they were created by the Department of Transportation’s (DOT) National Highway Traffic Safety Administration (NHTSA).

It's important to note the DOT doesn't conduct the tests for UTQG grading. The tests are performed by the tire manufacturers (or a 3rd-party testing company) and reported to the DOT. "

UTQG: Details of the Tire Ratings | Goodyear Tires
NHTSA does not assign uniform tire quality grades; however, they have the right to inspect all of the tire testing data as well as conduct regular compliance audits to ensure adherence to the appropriate grading.
Because the manufacturer is the one assigning the UTQG grades, these grades aren’t an absolute number for comparing. These grades – especially the treadwear figure – are generally extrapolated from testing data and should be best used when comparing tires of the same tire brand, not across different brands of tires.
