UTQG Tire Ratings Explained
Treadwear • Traction • Temperature — how the grades are tested, what they mean, and where their limits are.
REAL-WORLD EXAMPLE
A tire marked 500 A A has a UTQG rating of Treadwear 500, Traction A, and Temperature A. In standardized tests, a treadwear grade of 500 means the tire lasted about 5× longer than the government control tire rated 100 under the same conditions, and roughly 2.5× longer than a tire graded 200 in the same brand family. Traction A indicates strong straight‑line wet braking performance, and Temperature A means the tire resisted heat best at sustained high speeds on a test wheel. In real life, actual mileage and grip still depend heavily on driving style, vehicle, and climate.

UTQG Rating Reference Guide
| Rating Type | Range / Grade | Meaning in UTQG Tests | Typical Use Case |
|---|---|---|---|
| Treadwear | 100–200 | Shortest life in UTQG test; prioritizes grip | Max-performance / ultra-high-performance summer tires |
| Treadwear | 300–400 | Balanced wear vs. grip | Most daily-driver all-season and performance tires |
| Treadwear | 500–700+ | Longest life in UTQG test; often harder compound | Touring and grand touring all-season tires |
| Traction | AA / A | Best / very good straight-line wet braking | Many premium all-season and performance tires |
| Traction | B / C | Meets minimum wet braking standards | Budget or older designs (C is the legal minimum) |
| Temperature | A | Highest resistance to heat at highway speeds | High-speed rated and performance tires |
| Temperature | B / C | Adequate / minimum high-speed heat resistance | Standard passenger tires (C is the minimum allowed) |
These ranges are broad guidelines taken from how UTQG tests are structured, not strict cutoffs. Always check the specific tire’s datasheet, warranty, and independent tests to understand how it performs in real conditions.
How to Use This Guide
- Find the UTQG string on your tire sidewall (for example, 320 A A or 500 A B).
- Use the interactive tool to input different UTQG ratings and see how treadwear, traction, and temperature trade off against each other.
- Compare candidate tires: higher treadwear for longevity, higher traction and temperature grades for wet braking and high-speed durability.
- Read the explanations below to understand how UTQG is tested, what each grade covers, and why ratings are best used within the same brand line rather than across all brands.
UTQG Rating System Explained
Understanding UTQG Ratings in the Real World
What UTQG Is — and Is Not
UTQG was created to give consumers a simple way to compare basic aspects of tire quality under standardized tests: relative treadwear, straight-line wet braking traction, and high-speed heat resistance. It is not a complete performance score. UTQG says nothing about dry grip at the limit, snow and ice traction, hydroplaning resistance, noise, comfort, or steering feel, so it should always be read alongside professional tests and reviews.
Why Treadwear Is Only a Relative Index
Treadwear is measured by running the test tire and a control tire together over a fixed-distance course, then comparing how much each one wore. That gives a useful index for that company's product line, but because each manufacturer can choose its own control tire, a 400 from one brand is not guaranteed to deliver the same mileage as a 400 from another. For actual mileage expectations, the manufacturer's warranty and independent wear tests are often more informative.
Putting UTQG to Work When You Shop
When you compare tires, think of UTQG as a quick filter: higher Treadwear for potential longevity, AA/A Traction and A Temperature for safety under wet and high-speed conditions. From there, dive into detailed tests and owner feedback to choose a tire that matches your priorities for braking, cornering, comfort, and noise. Matching all four tires and following proper inflation and rotation intervals will do as much for real-world safety and tire life as choosing the perfect UTQG combination on paper.
