Uniform Tire Quality Grading (UTQG)
How to choose tires - treadwear, traction & temperature
The National Highway Traffic Safety Administration (NHTSA) established a rating system known as Uniform Tire Quality Grading to provide consumers with useful information to help them purchase tires. It's made up of three components:
-
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test track. A tire graded 200 would wear twice as long on the government test course under specified test conditions as one graded 100. Treadwear grades cannot be used to project tire mileage since there are a number of variables that affect wear - driving habits, service practices, differences in road characteristics and climate.
-
Traction
Traction grades - AA, A, B and C - go from highest to lowest. They represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. The testing does not take into account cornering, hydroplaning or acceleration.
-
Temperature
The temperature grades - A, B and C - go from highest to lowest, and represent the tire's resistance to the generation of heat.
While the ratings are established by NHTSA, the actual validation testing is performed by the tire manufacturers and independent testing companies they hire. That means there can be some inconsistencies in testing and results.
