Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance
Criteria Specification (TPC
Spec) system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same
TPC Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that
impact the overall performance
of the 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 MS
for mud and snow. See Tire
Sidewall Labeling on page 10‑34
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 10‑45
and Tire Rotation on page 10‑46
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.
