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 the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on the
rails which can damage the tire, wheel and other
parts of the 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 the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the 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 5-57andLoading the Vehicle on
page 4-19for 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 5-77.
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.
