Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its inflation
pressure regularly. See "Inflation
"Loading Your Vehicle" in the Index for information
regarding proper tire inflation and loading your vehicle.
For instruction on how to remove, install or store a spare
tire, see "Changing a Flat Tire" in the Index.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make sure the spare
is correctly inflated. Have the damaged or flat 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.
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.
