Traction - AA, A, B & C
Temperature - A, B & C
The traction grades, from highest to The temperature grades are A (the
lowest, are AA, A, B and C. Those highest), B and C representing the
grades represent the tire’s ability to tire’s resistance to the generation of
stop on wet pavement as measured heat and its ability to dissipate heat
under controlled conditions on spec- when tested under controlled condi-
ified government test surfaces of tions on a specified indoor laboratory
asphalt and concrete. A tire marked test wheel.
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.
C may have poor traction perform-
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
responds 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 labora-
tory test wheel than the minimum
required by law.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
