Buying New Tires - Buick 2012 Regal Owner's Manual

10-62 Vehicle Care
Tires will typically need to be
replaced due to wear before they
may need to be replaced due to
age. Consult the tire manufacturer
for more information on when tires
should be replaced.
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 60 and Tire Rotation on
page 10 60 for information on
proper tire rotation.
