Instruments and Controls 4-23

GM’s exclusive TPC Spec system
considers over a dozen critical
specications 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. SeeTire Sidewall Labeling on
page 9-42for 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. SeeTire Inspection
and Rotation on page 9-57for
information on proper tire rotation.{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 the vehicle. Be
sure to use the correct size,
brand, and type of tires on all
wheels. It is all right to drive
with the compact spare
temporarily, as it was
developed for use on the
vehicle. SeeCompact Spare
Tire on page 9-83.{CAUTION
If you use bias-ply tires on the
vehicle, the wheel rim anges
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.
