Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate  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.
Grade C corresponds to a level of performance which all passenger

car  tires  must  meet  under  the  Federal  Motor  Vehicle  Safety  Stan-

dard No. 109.
Grades B and A represent higher levels of performance on the labo-

ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly

inflated and not overloaded.

Excessive speed, underinflation, or excessive loading, either sepa-

rately  or  in  combination,  can  cause  heat  buildup  and  possible  tire

failure.
