If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information label. This label
is attached to the vehicle’s center pillar (B-pillar).
SeeLoading Your Vehicle on page 362, for
more information about the Tire and Loading
Information label.
Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires
not recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.
SeeBuying New Tires on page 460and
Accessories and Modications on page 392for
additional information.

{CAUTION:
Changing a tire can be dangerous.
The vehicle can slip off the jack and roll
over or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Be sure the transfer case is in a
drive gear—not in NEUTRAL.
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you can put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire on
the other side, at the opposite end of the
vehicle.When you have a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following steps will tell you next how to use
the jack and change a tire.
