UTQG classification Please first read and note the introductory information and heed the WARNINGS
Uniform Tire Quality Grading (UTQG): Quality grades can be found where applicable on the tire side- Treadwear (number) For example: Treadwear 200, Traction AA, Temperature A. All passenger car tires must conform to Federal Safety Requirements in addition to these grades. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under For example, a tire graded 150 (Treadwear-value 150) would wear one-and-one-half (1 1/2) times as The relative performance of tires depends upon the actual conditions of their use, however, and may Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's surfaces of asphalt and concrete. A tire marked C may have poor traction performance ⇒ . Temperature The temperature grades are A (the highest), B, and C representing the tire's resistance to the genera- Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and The grade C corresponds to a level of performance which all passenger car tires must meet under the mance on the laboratory test wheel than the minimum required by law ⇒ . WARNING The traction grade assigned to this tire is based on straight-ahead braking traction tests, and
WARNING The temperature grade for this tire is established for a tire that is properly inflated and not |
