Uniform Tire Quality Grading gets poor marks. No, UTQG is not a play dictated by a quarterback during a football huddle. The Uniform Tire Quality Grading is a comparative assessment applied to most car tires excluding winter tires to help consumers make informed decisions.

UTQG has been part of the tire industry since It was designed to create a tire manufacturing standard brands had to follow. But, is it still relevant today? Yet, some things do not change. UTQG ratings are still alive and kicking to this day and many drivers place their trust in them.

A system developed by the Department of Transportation, which helps consumers compare and rate tires on tread wear, traction, and temperature. The is tread wear which represents the tire's comparative wear when measured against the governments mandated tire, which is rated at So the tire rated at would wear four times longer than the government's mandated tire. However, please don't link treadwear grades with your projected tire mileage. The relative performance of tires depends upon the actual conditions of their use and may vary due to driving habits, service practices, differences in road characteristics and climate. Traction and Temperature ratings are rated A superior, B good and C average. Traction represents the level of grip the tire possesses. Temperature rating shows the tires' ability to disperse heat build-up. Heat is what causes a tire to deteriorate over time. Therefore, a tire that has a high temperature rating will disperse heat better than one with a low temperature rating. Toggle navigation. What is UTQG and what does it mean?

The coefficient of friction for the pair, test tire and surface, is then determined as the ratio of the longitudinal and vertical forces. The maximum coefficient of friction in the percent slip range is termed "peak" coefficient of friction, and the lower coefficient value for the fully locked tire is termed "slide" coefficient of friction.

Uniform Tire Quality Grading , commonly abbreviated as UTQG , is a set of standards for passenger car tires that measures a tire's treadwear , temperature resistance and traction.

UTQG ratings are still alive and kicking to this day and many drivers place their trust in them. Currently, the highest treadwear rating found on the US market is Yes, non-UTQG tires exist. Improved Handling. The UTQG rating measures treadwear, temperature and traction. It was designed to create a tire manufacturing standard brands had to follow. Bridgestone WeatherPeak. UTQG grades are not given for specific tires, including special trailer, winter, light truck, and different non-passenger car tires, as well as all tires with 12" or lower rim diameters. The tire tread wear rating, unlike the tire hardness ratings and traction grades, is portrayed by a number. This relationship can be represented by the following formula: [7]. This is enforced by NHTSA requiring documentation to justify any assignment of a grade on a tire, "These treadwear grades are no guarantee of actual tire mileage; differences in driving habits, service practices, climate, and road characteristics will affect a tire's longevity.
