Storing a Flat or Spare Tire
and Tools
{Warning
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.
{Warning
Failure to follow these tire storage
instructions carefully could result
in personal injury or property
damage if the hoist cable fails or
if the tire comes loose. Make sure
the tire is stored securely before
driving.
Caution
Storing an aluminum wheel with a
flat tire under your vehicle for an
extended period of time or with
the valve stem pointing up can
damage the wheel. Always stow
the wheel with the valve stem
pointing down and have the
wheel/tire repaired as soon as
possible.
Caution
The tire hoist can be damaged if
there is no tension on the cable
when using it. To have the
necessary tension, the spare or
road tire and wheel assembly
must be installed on the tire hoist
to use it.
{Warning
An improperly stored spare tire
could come loose and cause a
crash. To avoid personal injury or
property damage, always store
the spare tire when the vehicle is
parked on a level surface.
Store the tire under the rear of the
vehicle in the spare tire carrier.

Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure0333
and
Vehicle Load Limits 0196. For
instructions on how to remove,
install, or store a spare tire, see Tire
Changing 0349. If equipped with a temporary use
full-size spare tire, it is indicated on
the tire sidewall. See
Tire Sidewall
Labeling 0329. This spare tire
should not be driven on over
112 km/h (70 mph), or 88 km/h
(55 mph) when pulling a trailer, at
the proper inflation pressure. Repair
and replace the road tire as soon as
it is convenient, and stow the spare
tire for future use.
Caution
If the vehicle has four-wheel drive
and a different size spare tire is
installed, do not drive in
four-wheel drive until the flat tire
is repaired and/or replaced. The
vehicle could be damaged and
the repairs would not be covered
by the warranty. Never use
four-wheel drive when a different
size spare tire is installed on the
vehicle.
The vehicle may have a different
size spare tire than the road tires
originally installed on the vehicle. This spare tire was developed for
use on this vehicle, so it is all right
to drive on it. If the vehicle has
four-wheel drive and a different size
spare tire is installed, drive only in
two-wheel drive.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare tire is
correctly inflated.
Have the damaged or flat road tire
repaired or replaced and installed
back onto the vehicle as soon as
possible so the spare tire will be
available in case it is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep your spare tire and its
wheel together. If the vehicle has a
spare tire that does not match the
original road tires and wheels in size
and type, do not include the spare in
the tire rotation.
