tires depends upon the actual
conditions of their use, however,
and may depart significantly from
the norm due to variations in
driving habits, service practices,
and differences in road
characteristics and climate.
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 test surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
The traction grade
assigned to this tire is
based on braking (straight
ahead) 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

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Tires that are larger or smaller
than your vehicle's original tires
may also affect the accuracy of
your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have all
weather treads to provide traction
in rain and snow. However, in some
climates, you may need to use
snow tires and chains. If you need
to use snow tires and chains, you
must install steel wheels of the
same size and specifications as
those originally installed.
