GM's exclusive TPC Spec system
considers over a dozen critical
specifications that impact the
overall performance of your
vehicle, including brake system
performance, ride and handling,
traction control, and tire pressure
monitoring performance. GM's TPC
Spec number is molded onto the
tire's sidewall near the tire size.
If the tires have an all season tread
design, the TPC spec number will
be followed by an MS for mud and
snow. See
for additional
information.
GM recommends replacing tires in
sets of four. 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. See
information on proper tire rotation.
Tires could explode during
improper service. You or others
could be injured or killed if you
attempt to mount or dismount
a tire. Only your dealer or an
authorized tire service center
should mount and dismount the
tires.
Mixing tires could cause you to
lose control of your vehicle 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
and
for
vehicle. Be sure to use the
correct size, brand, and type of
tires on all wheels.
Your vehicle may have a compact
spare tire and wheel assembly.
It is all right to drive with your
vehicle's compact spare tire
temporarily. 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.
(Continued)
Use only radial-ply tires with
the wheels on the vehicle.
