Full-Size Spare Tire

If this vehicle came with a full-size spare
tire, it was fully inflated when new,
however, it can lose air over time.
Check the inflation pressure regularly. See
Tire Pressure 0 341 and
Vehicle Load Limits 0 217 for information
regarding proper tire inflation and loading
the vehicle. For instructions on how to
remove, install, or store a spare tire, see Tire
Changing 0 356.
After installing the spare tire on the vehicle,
stop as soon as possible and check that the
spare is correctly inflated. The spare tire is
made to perform well at speeds up to
112 km/h (70 MPH) at the recommended
inflation pressure, so you can finish
your trip.
Have the damaged or flat road tire repaired
or replaced and installed back onto the
vehicle as soon as possible so the spare tire
will be available in case it is needed again.
Do not mix tires and wheels of difference
sizes, because they will not fit. Keep the
spare tire and its wheel together.
Caution
If the vehicle has four-wheel drive and a
different size spare tire is installed, do
not drive in four-wheel drive until the flat
tire is repaired and/or replaced. The
vehicle could be damaged and the repairs
would not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed on the
vehicle.
The vehicle may have a different size spare
tire than the road tires originally installed
on the vehicle. This spare tire was developed
for use on this vehicle, so it is all right to
drive on it. If the vehicle has four-wheel
drive and a different size spare tire is
installed, drive only in two-wheel drive.
If the vehicle has a spare tire that does not
match the vehicle s original road tires and
wheels, in size and type, do not include the
spare in the tire rotation.
