Hankook Ventus S1 evo Z vs Michelin Pilot Sport 4

Source: NHTSA UTQG tire ratings, tire-recall file, and equipment plant codes, last updated November 9, 2026 (UTC).

About this data

UTQG grades are assigned by the manufacturer under 49 CFR 575.104. Treadwear is a relative grade from a government test course, not a mileage figure. Grades from different brands are only loosely comparable. What treadwear, traction, and temperature mean. What treadwear numbers mean. A tire that is not in the list is covered in why a tire may have no UTQG rating. The ratings file has no category field. Data last verified November 9, 2026 (UTC).

The treadwear median is the middle usable grade when the count is odd, and the mean of the two middle grades when the count is even. A usable grade is a positive whole number. Size text is shown as NHTSA published it.

This is one example comparison from the tire line comparison. The token in the label above is the name-token list that selected the pair. It is not an NHTSA category. Open these lines in the compare tool.

Questions

Can UTQG grades from different brands be compared directly?

NHTSA lists manufacturer-assigned grades under 49 CFR 575.104. Treadwear is a relative grade from a government test course, not miles, and grades from different brands are only loosely comparable.
