Spare Tire
Your vehicle, when new, had a fully inated spare tire.
A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire Pressure

your vehicle. For instruction on how to remove, install
or store a spare tire, seeChanging a Flat Tire on
page 5-70andRemoving the Flat Tire and Installing the
Spare Tire on page 5-79.
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 tires—those originally installed on your vehicle.
This spare tires was developed for use on your
vehicle, so it’s 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.
