Mixing tires could cause you
to lose control while driving.
If you mix tires of different
sizes, 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, brands, or types may
also cause damage to your
vehicle. Be sure to use the
correct size, brand, and type
of tires on all wheels. It is
all right to drive with your
compact spare temporarily, as
it was developed for use on
your vehicle. See
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.
.
Vehicles that have a tire
pressure monitoring system
could 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
.
Your vehicle's original
equipment tires are listed
on the Tire and Loading
Information Label. See
more information about the Tire
and Loading Information Label
and its location on your vehicle.
