TRACTION capability greater than tires of C grade, but not as good as tires of AA or A grade.TREADWEAR grade less than that of a tire graded 100.EXAMPLE #1: A tire with the ratings of TREADWEAR 80, TRACTION B, TEMPERATURE C, is interpreted by the manufacturer as having: Excessive speed, under inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tireįailure. WARNING:The temperature grade is established for a tire that is properly inflated and not overloaded. Performance on the laboratory test wheel than the minimum required by law. Grades A and B represent higher levels of The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. Life, and excessive temperature can lead to sudden tire failure. Sustained high temperature can cause the material of the tire to degenerate and reduce tire Resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. The comparative grade letters, A, B, and C (A being the highest and C being the lowest) represent the tire's TEMPERATURE A, B, C The temperature grade is based on an indoor, high-speed test that meets government-specified requirements. WARNING: The traction grade assigned is based on braking (straight ahead) traction test and does not include cornering (turning) traction. The comparative tire grade letters, AA, A, B, and C (AA being the highest and C being the lowest) represent the tire's ability to stop the vehicle on wet pavement under the controlled test conditions. The traction grade is based on a straight-ahead wet braking traction test and does not include a cornering TRACTION AA, A, B, C The traction grade is based on wet skid tests of a tire on government-specified concrete and asphalt surfaces. The relative performance of tires depends upon the actual conditions of their use and may depart significantly from the norm due to variations inĭriving habits, service practices and differences in road characteristics. For example, a tire gradedġ50 would wear one and a half (1 1/2) times as well as a tire graded 100 under the controlled test conditions. TREADWEAR The treadwear grade is a comparative grade assigned by the manufacturer based on the wear rate of a tire when tested under controlled conditions on a course that meets government-specified requirements. DOT QUALITY GRADES All passenger car tires must conform to Federal Safety Requirements in addition to these grades. Tire manufacturers and brand name owners are required to grade regularĪnd all-season tires in three categories: Treadwear, Traction, and Temperature. UTQG designates the comparative performance levels of a tire based upon government-specified tests. Specifically to your particular driving habits, conditions, etc., is a possibility. As a result, misinterpreting the comparative data as it relates However, the ratings are based upon test results achieved under very specific conditions. **Due to Current Product Backorders/Shortage, Please Call/Email/Text us before ordering to confirm inventory status as this changes on a daily basis.Is intended to provide simple, comparative data for your use in making an informed buying decision.
