WARNING!
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, under-
inflation, or excessive loading, either separately or in combina-
tion, can cause heat buildup and possible tire failure.
DEPARTMENT OF TRANSPORTATION UNIFORM TIRE QUALITY GRADES
Temperature Grades
The emperature 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 perfor-
mance, which all passenger vehicle 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 .
