Vehicle Care

Buying New Tires

GM has developed and matched
specific tires for the vehicle.
The original equipment tires
installed on the vehicle, when
it was new, were designed
to meet General Motors
Tire Performance Criteria
Specification (TPC Spec)
system rating. If you need
replacement tires, GM strongly
recommends that you get
tires with the same TPC Spec
rating. This way, the 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'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
an MS for mud and snow.
See

Tire Sidewall Labeling on

page 10

for additional

information.

GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires

will help keep the 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 the
vehicle. See

Tire Inspection on

and

for information on

proper tire rotation.

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.
