Replacing less than a full set of tires
can affect the braking and handling
performance of your vehicle. See
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or dismount
the tires.
Winter tires with the same speed
rating as your original equipment
tires may not be available for H, V,
W and ZR speed rated tires. If you
choose snow tires with a lower
speed rating, never exceed the tire's
maximum speed capability.
Mixing tires could cause you to
and
lose control while driving. If you
.
mix tires of different sizes (other
than those originally installed on
your vehicle), brands, or types
(radial and bias-belted tires), the
vehicle may not handle properly,
and you could have a crash.
Using tires of different sizes
(other than those originally
installed on your vehicle), brands
or types, may also cause damage
to your vehicle. Be sure to use
the correct size, brand, and type
tires on all four wheels.
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your vehicle's
tires with those that do not have
a TPC Spec number, make sure
they are the same size, load range,
speed rating, and construction type
(radial and bias belted tires) as your
vehicle's original tires.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low pressure warning
if non TPC Spec rated tires are
installed on it. Non TPC Spec
rated tires may give a low pressure
warning that is higher or lower than
the proper warning level you would
get with TPC Spec rated tires. See
