Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire. Although
the compact spare tire was fully inated when the vehicle
was new, it can lose air after a time. Check the ination
pressure regularly. It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle, stop as
soon as possible and make sure the spare tire is correctly
inated. The compact spare is made to perform well at
speeds up to 65 mph (105 km/h) for distances up to
3,000 miles (5 000 km), so you can nish your trip
and have the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the spare
with a full-size tire as soon as possible. The spare tire
will last longer and be in good shape in case it is needed
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 the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not t. Keep the
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.Spare Tire
Your vehicle may have a spare tire, which, when new,
was fully inated. A spare tire may lose air over time, so
check its ination pressure regularly. SeeInflation - Tire
Pressure on page 5-60andLoading the Vehicle on
page 4-20for information regarding proper tire ination
and loading your vehicle. For instructions on how to
remove, install or store a spare tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-81.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road tire
repaired or replaced as soon as you can and installed
back onto your vehicle. This way, a spare tire will be
available in case you need it again.
Your vehicle may have a different size spare tire
than the road tire originally installed on your vehicle.
This spare tire was developed for use on your vehicle,
so it is all right to drive on it.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
