DOT Tire Quality Grading (U.S. Cars)

Temperature

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 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
performance which all passenger car
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.

Warning: The temperature grade for

this tire is established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading either

separately or in combination, can
cause heat build-up and possible tire

failure.
