•
The tire has a puncture, cut or other damage that
can't be repaired well because of the size or
location of the damage.

Buying New Tires

To find out what kind and size of tires you need, look at
the Certification/Tire label or the Tire and Loading
Information label. For examples of these labels and their
location on your vehicle, see Loading Your Vehicle on
page 4-31.
The tires installed on your vehicle when it was new had a
Tire Performance Criteria Specification (TPC Spec)
number on each tire's sidewall. When you get new tires,
General Motors recommends that you get tires with that
same TPC Spec number. That way your vehicle will
continue to have tires that are designed to give proper
endurance, handling, speed rating, load range, traction,
ride and other things during normal service on your
vehicle. If your tires have an all-season tread design, the
TPC number will be followed by an "MS" (for mud
and snow).
If you replace your tires with those not having a TPC
Spec number, make sure they are the same size, load
range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
CAUTION:
{
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires) the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels.
CAUTION:
{
If you use bias-ply tires on your 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 your vehicle.
