WARNING (Continued)
damage to your vehicle. Be sure
to use the same size, brand, and
type of tires on all wheels.
Your vehicle may have a different
size spare than the road tires
(those originally installed on your
vehicle). When new, your vehicle
included a spare tire and wheel
assembly with a similar overall
diameter as your vehicle's road
tires and wheels, so it is all right
to drive on it. Because this spare
was developed for use on your
vehicle, it will not affect vehicle
handling.
WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing 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.
Vehicle Care
Vehicles that have a tire pressure
monitoring system may give an
inaccurate low pressure warning if
non TPC Spec-rated tires are
installed on your vehicle. 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 Tire Pressure
Monitor System on page 10 56.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9 23
for more information about the Tire
and Loading Information label and
its location on your vehicle.
