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 5-63 and Loading the Vehicle on page 4-44
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 5-90 and Storing
a Flat or Spare Tire and Tools (SUT) on page 5-95
or Storing a Flat or Spare Tire and Tools (SUV)
on page 5-98.
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. Do not mix tires and wheels of different sizes,
because they will not fit. Keep your spare tire and its
wheel together.
