■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the ge neration of heat and its ability to dissi-
pate heat when tested under contr olled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can c ause 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 passeng er
car tires must meet under the Fe deral 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 pro perly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can c ause heat buildup and possible t ire
failure.
