Buying New Tires - Chevrolet Caprice 2011 Owner's Manual

10-62 Vehicle Care
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle.
Park a vehicle that will be stored
for at least a month in a cool, dry,
clean area away from direct sunlight
to slow aging. This area should be
free of grease, gasoline, or other
substances that can deteriorate
rubber.
Parking for an extended period
can cause flat spots on the tires
that may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires
or raise the vehicle to reduce the
weight from the tires.

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 47 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 59
and Tire Rotation on page 10 60
for information on proper tire
rotation.
