About UTQG Ratings |
| The Federal Government Uniform Tire Quality Grading
Standards are compiled of three characteristics of different standards.
Below we have defined these three characteristics. |
| TRACTION |
| The traction grades, from highest to lowest, are AA, A, B, and
C. These different grades are symbolic to how well the tires can
stop on wet pavement. This is tested on various courses by the
government. The Traction testing is performed on a straight road.
So this doesn't include any cornering or other handling issues. |
| TREADWEAR |
| The treadwear grade is based on the rate in which the tire wears
down under controlled conditons on a government test track. The
treadwear can vary based on an individual's driving style, climate,
or road conditions. |
| TEMPERATURE |
| The temperature grades are rated as A, B, or C. A being the highest
and C being the lowest. These rates are compiled by the tire being
placed under extreme temperatures in controlled environments.
This temperature test is also something that is done while the
tire is standing still. The tire spinning could cause the tire
to fail a little quicker than in the tests. |
