The U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration's (NHTSA) Uniform Tire Quality Grade Standards (UTQG) were originated to provide consumers with useful information to help them purchase tires based on their relative treadwear, traction and temperature capabilities.

Manufacturers are not required to provide UTQG standards for winter/snow tires, deep treaded light truck tires and other select tires.
