UTQG
Tires are rated by the U.S. government using a standardized system that measures treadwear, traction, and temperature resistance. Discover how UTQG grades work and what the numbers and letters on your tire’s sidewall reveal about its longevity, wet-weather grip, and temperature tolerance, helping you to make an informed decision about your tire.
UTQG stands for Uniform Tire Quality Grading, which is a U.S. Department of Transportation rating system that helps consumers compare tire performance. The tire’s UTQG can be found on the sidewall, and it grades tires based on three criteria:
Treadwear (Longevity)
Go to detailed Treadwear Guide
Traction (Wet Braking)
Go to detailed Traction Guide
Temperature (Heat Resistance)
Go to detailed Temperature Guide
This rating helps consumers compare the tire’s longevity, wet-weather braking performance, and heat resistance. It is often referred to as tire rating or tire quality grade.
Where To Find The UTQG Rating On Your Tire?
The UTQG rating is molded into the sidewall of every tire. Look for a sequence of numbers and letters, such as 600 AA, printed alongside other tire information, like the tire size and speed rating. It is typically located on the upper sidewall, between the tire brand name and the rim edge.
Which UTQG Rating Is Right For Me?
Daily Commuter
Needs to look for a treadwear rating of 600 or higher with an A or AA traction grade. Touring or highway tires offer the best balance and longevity for everyday driving.
Performance Driver
Prioritize an AA traction grade and a temperature grade of A. A lower treadwear rating of 300-500 is good for performance tires, since these vehicles prioritize grip over longevity.

Tire Limitations to Keep in Mind
UTQG ratings are a useful starting point for comparing tires, but come with important limitations. Manufacturers self-test their own products without independent verification, and treadwear ratings are based on controlled conditions that may not reflect real-world driving. The traction grade only measures straight-line wet braking, ignoring dry performance, cornering, and winter conditions, while the outdated locked-wheel test does not account for modern ABS systems. Ratings are also unreliable for cross-brand comparisons and do not apply to light truck, winter, or specialty tires. Use UTQG alongside professional reviews, owner feedback, and warranty coverage for a more complete tire decision.
What UTQG Does Cover:
- Provide a standardized baseline for comparing tire longevity within the same brand’s lineup.
- Establishes minimum wet braking performance thresholds to ensure basic safety standards.
- Confirms a tire's ability to handle sustained high-speed driving without heat-related failure.
- Helps narrow initial tire choices based on relative durability expectations.
What UTQG Does Not Cover:
- Guaranteed real-world tread life in specific mileage terms.
- Dry braking performance, cornering grip, or handling characteristics.
- Snow and ice traction, or hydroplaning resistance.
- Ride comfort, road noise levels, or fuel efficiency.
- Modern ABS braking system performance.
- Reliable cross-brand tire comparisons.
Frequently Asked Questions
The UTQG, or uniform tire quality grading, is a tire rating developed by the Department of Transportation and the National Highway Traffic Safety Administration. It rates a standard that drivers can use to determine the estimated durability and longevity of each tire. It shows the treadwear grades, temperature ratings, and traction ratings for tires.
The tire rating indicates very high treadwear longevity (600), which means that it can last 6 times longer than a reference tire rated 100. It offers excellent wet braking traction (A), which is the highest grade for stopping ability on wet roads. And the high heat resistance is (B), which means that the tire can safely handle high-speed driving while resisting heat.
UTQG 700 AA means your tire has a treadwear rating of 700, indicating long tread life, a traction grade of AA for excellent wet braking performance, and a temperature grade of A, meaning the tire effectively dissipates heat at high speeds.
The UTQG rating consists of three parts: the treadwear grade, traction ratings, and temperature ratings. The treadwear rate is a numerical rating indicating how long the tire tread is expected to last compared to a baseline of 100. The traction measures the tire’s ability to stop on wet pavement, while the temperature rating indicates how well the tire resists and dissipates heat at high speeds.
The best UTQG rating for traction is AA, which indicates the highest level of wet braking performance. It means that the tire can stop effectively on wet pavement over a shorter distance compared to tire rated A, B, and C. For everyday driving, an A rating is still very good, while the B or C ratings are less common and generally found on specialty or older tire models.
A good treadwear rating depends on the driving needs and tire type. For everyday passenger and touring tires, a rating of 600 or higher is considered good, offering long tread life and better value over time. On the other hand, performance tires typically carry a lower rating of 200-400, as their softer rubber prioritizes grip over longevity. Touring and highway tires have the best balance and durability, and correspond to tread life warranties of 50,000-80,000 miles.
