Buying New Tires - Chevrolet Kodiak 2008 Owner's Manual

If your vehicle has four-wheel drive, the axle differentials,
propshafts, and transfer case may be damaged if tires
of different sizes, brands or tread types are installed
on the front and rear axles. That damage would not be
covered under your warranty.

Buying New Tires

GM has developed and matched specific tires for your
vehicle. If you need replacement tires, GM strongly
recommends that you get tires that are the same size,
brand, load range, speed rating, and construction type
(radial and bias-belted tires) as your vehicle's original
tires. This way, your vehicle will continue to have tires
that are designed to give the same performance and
vehicle safety, during normal use, as the original tires.
GM recommends replacing tires in sets of six or eight as
applicable. This is because uniform tread depth on all
tires will help keep your vehicle performing most like it
did when the tires were new. Replacing less than a full
set of tires can affect the braking and handling
performance of your vehicle.
CAUTION:
{
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 your
vehicle's 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.
