What is UTQG?

UTQG rating diagram

Uniform tire quality grading (UTQG) is a series of results set by the U.S. Department of Transportation's National Highway Traffic Safety Administration to measure a tire's treadwear, traction and temperature. UTQG standards are not tested by the U.S. DOT but by tire manufacturers. However, if inconsistencies are detected in a manufacturer's results, the National Highway Traffic Safety Administration can independently test each tire to ensure proper grading. These ratings can be found on any sidewall of a tire or on the doorjamb placard.

UTQG ratings

  • Treadwear ratings measures tire durability compared to a weaker, standard reference tire
  • Traction ratings grade how well a tire stops on wet surfaces
  • Temperature ratings determine how a fully inflated tire resists and disperses heat
