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 MS for mud
and snow. See Tire Sidewall
Labeling on page 10 40 for
additional information.
GM recommends replacing all
the tires at the same time.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time. See
Tire Inspection on page 10 50
and Tire Rotation on page 10 50
for information on proper tire
rotation.
WARNING
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
WARNING
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.
Vehicle Care
WARNING
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
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.
See Tire Pressure Monitor
System on page 10 46.
