Most passenger and light-truck tires carry a UTQG (Uniform Tire Quality Grading) stamp with three values. They’re a useful way to compare tires.
Treadwear
A relative number like 400 or 600. Higher generally means the tread is rated to last longer. It’s most reliable when comparing tires from the same manufacturer, since testing varies between brands.
Traction (AA, A, B, C)
Measures straight-line wet stopping grip on standardized surfaces. AA is the best, C the lowest.
Temperature (A, B, C)
Indicates resistance to heat at speed. A is the highest rating; all tires sold must meet at least a C.
Use UTQG as one input alongside the tire’s warranty mileage, season rating, and reviews — not as the only deciding factor.
