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 318and
Accessories and Modifications on page 249for
additional information.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven.
It could fail suddenly and cause a crash.
If you have to replace a wheel, use a new
GM original equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and
only when you must. Use only SAE Class
“S” type chains that are the proper size for
your tires. Install them on the front tires
and tighten them as tightly as possible with
the ends securely fastened. Drive slowly
and follow the chain manufacturer’s
instructions. If you can hear the chains
contacting your vehicle, stop and retighten
them. If the contact continues, slow down
until it stops. Driving too fast or spinning
the wheels with chains on will damage your
vehicle.

Storing a Flat or Spare Tire
and Tools
{CAUTION:
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.To store a flat or spare tire, do the following:
1. Put the flat or spare tire in the compact spare
tire compartment, then secure the retainer.
2. Store the jack in its housing in the cargo area.
Secure the jack by turning the retainer
clockwise.
3. Store the tools securely in the foam tray and
place the tray on top of the tire.
4. Replace the trim cover.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size
tire as soon as you can. SeeCompact Spare Tire
on page 334.

Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air
after a time. Check the inflation pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make
sure your spare tire is correctly inflated. The
compact spare is made to perform well at speeds
up to 50 mph (80 km/h), so you can finish your
trip and have your full-size tire repaired or replaced
where you want. Of course, it is best to replace
your spare with a full-size tire as soon as you can.
Your spare will last longer and be in good shape
in case you need it again.Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or
wheel with other wheels or tires. They will not fit.
Keep your spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.
