Inflation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Neither tire underinflation nor
overinflation is good. Underinflated tires,
or tires that do not have enough air, can
result in:
.Tire overloading and over-heating which
could lead to a blowout.
.Premature or irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that have too much
air, can result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from road hazards. A vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle's original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support your
vehicle's maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example
of the Tire and Loading Information label, see
Loading the Vehicle
on page 5‑18. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more. Do not
forget to check the compact spare tire, it should
be at 60 psi (420 kPa). For additional information
regarding the compact spare tire, see Compact
Spare Tire
on page 6‑97.

Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, wheel nuts, and TPMS sensors
for your vehicle.
{WARNING:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts can be dangerous. It could affect
the braking and handling of the vehicle. Tires can
lose air, and cause loss of control, causing a
crash. Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.Notice:
The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
See Changing a Flat Tire
on page 6‑88for more
information.
Used Replacement Wheels
{WARNING:
Replacing a wheel with a used one is dangerous.
How it has been used or how far it has been
driven may be unknown. It could fail suddenly and
cause a crash. When replacing wheels, use a new
GM original equipment wheel.
