Buying New Tires - Cadillac 2011 Escalade Owner's Manual

10-66 Vehicle Care
Some commercial truck tires may
not have treadwear indicators.
See Tire Inspection on page 10 64
and Tire Rotation on page 10 64
for additional information.
The rubber in tires ages over time.
This is also true for the spare tire,
if the vehicle has one, even if it is
not being used. Multiple conditions
affect how fast this aging takes
place, including temperatures,
loading conditions, and inflation
pressure maintenance. 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 your vehicle.
The original equipment tires
installed on your 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, your vehicle will continue
to have tires that are designed to
give the same performance and
vehicle safety, during normal use,
as the original tires.
