Traction
Directional Tires*
The traction grades, from highest to lowest, are
AA, A, B and C. The grades represent a tire's
ability to stop on wet pavement as measured
under controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked 'C' may have poor
traction performance.
Directional tires give greater benefit when they
rotate in a forward direction, i.e., when the
vehicle is moving forwards. They give
enhanced levels of deep-water grip while still
maintaining low tyre noise generation.
Should a tyre be fitted to a vehicle in the wrong
directional sense, these benefits will only be
maintained if the tyre is remounted to the rim so
that it rotates in the direction indicated on the
sidewall.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
There are two types of directional tyre and the
direction indicators are shown in the illustration
below.
Temperature
A
The temperature grades A (the highest), B, and
C, represent a 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 temperatures can cause the
material of a tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure.
B
The grade 'C' corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor 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 overloaded. Excessive speed, under
inflation, or excessive loading, either
separately or in combination can cause heat
buildup and possible tire failure.
