What is UTQG?

Breaking the Code: What is the UTQG Rating on My Tires?

Tire UTQG Code

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 measure 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.
