uuChecking and Maintaining TiresuDOT Tire Quality Grading (U.S. Vehicles)  
Warning: The traction grade  
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.  
assigned to this tire is based on  
and does not include acceleration,  
cornering, hydroplaning, or peak  
traction characteristics.  
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.  
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 Vehicle  
Safety Standard No. 109. Grades B and A represent higher levels  
of performance on the laboratory test wheel than the minimum  
required by law.
