Full-Size 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 Tire Pressure on page 10‑66
and Vehicle Load Limits on
page 9‑25 for information regarding
proper tire inflation and loading your
vehicle. For instruction on how to
remove, install or store a spare tire,
see “Removing the Flat Tire and
Installing the Spare” and “Storing a
Flat or Spare Tire and Tools” under
Tire Changing on page 10‑86.
Notice: If the vehicle has
four-wheel drive and the different
size spare tire is installed on the
vehicle, do not drive in four-wheel
drive until you can have your
flat tire repaired and/or replaced.
You could damage the vehicle,
and the repair costs would not
be covered by your warranty.
Never use four-wheel drive when
the different size spare tire is
installed on the vehicle.
Your vehicle may have a different
size spare tire than the road tires
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
four-wheel drive and the different
size spare tire is installed, keep
the vehicle in two-wheel drive.
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare
tire 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, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of
different sizes, because they will
not fit. Keep your spare tire and its
wheel together. 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.
