Traction A, B, C The traction grades, from highest to lowest, are A, B, and C, and they represent the 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. Warning: The traction grade assigned to this tire is based on braking (straightahead) traction tests and does not include cornering (turning) traction. - 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 overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Temperature - A, B, C 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 ofperformance

Traction
-
A,
B,
C
The traction grades, from highest to lowest, are
A,
B,
and
C,
and they represent the 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.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature
-
A,
B,
C
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
overloaded. Excessive speed, underinflation,
or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel
Alignment
and
Tire
Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire
life
and best overall performance.
In most cases, you
will not need to have your wheels
aligned again.
However, if
you notice unusual tire wear
or your vehicle pulling one way
or
the other, the
alignment may
need to be reset. If
you notice your
vehicle vibrating when driving on a smooth road, your
wheels may
need to be rebalanced.
