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 - Tire
Pressure on page 393 and Loading Your Vehicle
on page 296 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 Tire
on page 408 and Storing a Flat or Spare Tire and
Tools on page 418.

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.
Notice: If your vehicle has four-wheel drive
and the different size spare tire is installed
on your vehicle, do not drive in four-wheel
drive until you can have your flat tire repaired
and/or replaced. You could damage your
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 your vehicle.
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.
