| The relationship between the section height and section width of a tire expressed as a percentage of section width. If the section height is one half the section height, the aspect ratio is 50%. |
| Speed Symbol |
| Indicates the max speed at which the tire can carry a load corresponding to its load index (except for speeds above 210 km/h) under service conditions specified by the tire manufacturer. |
| UTQG (Uniform Tire Quality Grade) |
UTQGS is a standard defined by the DOT of USA for grading the performances of tires in the areas of TREADWEAR, TRACTION and TEMPERATURE RESISTANCE. It applies only to car tires with a rim diameter of 13" and larger, but not to winter tires.
Tread Wear The measure of the life of a tire tread. The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: the traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.
Temperature The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: the temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination can cause heat buildup and possible tire failure. |
