Full-Size Spare Tire

This vehicle, when new, may have
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 60 and Vehicle Load Limits
on page 9 12 for information
regarding proper tire inflation and
loading the vehicle. For instruction
on how to remove, install or store a
spare tire, see Removing the Flat
Tire and Installing the Spare Tire
and Storing a Flat or Spare Tire
and Tools under Tire Changing on
page 10 77.
After installing the spare tire on the
vehicle, you should stop as soon as
possible and make sure 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 as soon as you
can and installed back onto the
vehicle. This way, a 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 the spare tire and its
wheel together.
