"The Treadwear Grade of a tire is the numeric portion of the Uniform Tire Quality Grade Standards (UTQG) that are printed on the sidewall of a tire. These standards were enacted by the National Highway Traffic Safety Administration (NHTSA), which is part of the United States Department of Transportation. Higher treadwear numbers indicate that the tread of a tire, and hence the tire itself, should last longer."
