tire size FORD EXPEDITION 1998 1.G Owners Manual

The air suspension shut-off switch
is located behind an access panel
underneath the passenger side
instrument panel.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior
to jacking, hoisting or towing
your vehicle.
Normal vehicle operation does not
require any action by the driver.
TRACTION-LOK AXLE (IF
EQUIPPED)
This axle provides added traction
on slippery surfaces, particularly
when one wheel is on a poor
traction surface. Under normal
conditions, the Traction-Lok axle
functions like a standard rear axle.
Extended use of other than the
manufacturer's specified size tires
on a Traction-Lok rear axle could
result in a permanent reduction in
effectiveness. This loss of
effectiveness does not affect
normal driving and should not be
noticeable to the driver.
To avoid injury, never run
the engine with one wheel
off the ground, such as when
changing a tire.

If your vehicle is equipped with
the optional heavy duty trailer tow
wiring, it is pre-wired for trailer
towing. An electrical connector is
provided under the instrument
panel for installing a
customer-supplied electric brake
controller. Another electrical
connector is provided at the hitch.
This connector provides power to
the trailer for taillamps, stop and
turn lamps, back up lamps, battery
charge, electric brakes (when a
customer provided controller is
installed) and ground. The kit
included with your vehicle
provides you with adaptors to
attach the brake controller and
convert the hitch connector for
Class I trailer usage.

Certification label. For load
specification terms found on the
label, refer toVehicle loadingin
this chapter. Remember to figure
in the tongue load of your loaded
trailer when figuring the total
weight.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of control and
personal injury.

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Tires that are larger or smaller
than your vehicle's original tires
may also affect the accuracy of
your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have all
weather treads to provide traction
in rain and snow. However, in some
climates, you may need to use
snow tires and chains.
Follow these guidelines when using
snow tires and chains:
²Use only cable type chains
