µWarning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not
overloaded. Excessive speed,
underinf lation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire f ailure.
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 specif ied 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 f ailure. The
grade C corresponds to a level of
perf ormance, which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Saf ety
Standard No. 109. Grades B and A
represent higher levels of
perf ormance on the laboratory test
wheel than the minimum required by
law. Temperature A,B,C
