Vehicle specifications
■Temperature A, B, C
The temperature grades are A 
(the highest), B, and C, repre-
senting the tire’s resistance to 
the generation of heat and its 
ability to dissipate heat when 
tested under controlled condi-
tions on a specified indoor labo-
ratory 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 Fed-
eral Motor Vehicle Safety Standard 
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 tha
t 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 fail-
ure.
