Tire Rotation
WARNING: If the tire label
shows different tire pressures for
the front and rear tires and the
vehicle has a tire pressure
monitoring system, then you
need to update the settings for
the system sensors. Always
perform the system reset
procedure after tire rotation. If
you do not reset the system, it
may not provide a low tire
pressure warning when
necessary.
Note: If your tires show uneven
wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation.
Note: Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. A
dissimilar spare wheel and tire
assembly is defined as a spare
wheel and tire assembly that is
different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements. Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.

four-wheel drive vehicles (front
tires at left of diagram)
Sometimes irregular tire wear can
be corrected by rotating the tires.
USING SNOW CHAINS
WARNING:
Snow tires must be the
same size, load index and speed rating
as those originally provided by Ford. Use
of any tire or wheel not recommended
by Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of
control, vehicle rollover, personal injury
and death. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
377
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Wheels and TiresE142548

Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
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 cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an
accessory or equivalent. Other
conventional link type chains may
contact and cause damage to the
vehicle's wheel house and/or body.
• Do not install chains on the front tires
as this may interfere with suspension
components.
• Only certain snow cables or chains
have been approved by Ford/Lincoln
as safe for use on your vehicle with the
following tires: 265/70R17 and
275/65R18.
• You should install snow cables or
chains that have been rated as SAE
Class S. •
Install chains securely, verifying that
the chains do not touch any wiring,
brake lines, or fuel lines.
• Do not exceed 31 mph (50 km/h) or
less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.
Note: You should only use tire sealants in
roadside emergencies as they could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function.

Changing Tires With a Tire
Pressure Monitoring System
Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See When Inflating Your Tires in
this chapter.
Understanding Your Tire Pressure
Monitoring System The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information display.
See General Information (page 119). The
low tire pressure warning light will turn on
if the tire pressure is significantly low. Once
the light is illuminated, your tires are
under-inflated and need to be inflated to
the manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
could increase about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure
could decrease about
3 psi (21 kPa) for a
drop of 30°F (17°C) in ambient
temperature. This lower pressure value
could be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system warning
light for low tire pressure. If the low tire
pressure warning light is on, visually check
each tire to verify that no tire is flat. If one
or more tires are flat, repair as necessary.
Check the air pressure in the road tires. If
any tire is under-inflated, carefully drive
the vehicle to the nearest location where
air can be added to the tires. Inflate all the
tires to the recommended inflation
pressure.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on this vehicle. If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
system sensors.
See Tire Pressure
Monitoring System (page 378). Replace
the spare tire with a road tire as soon as
possible. During repairing or replacing of
the flat tire, have the authorized dealer
inspect the system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided.
If the dissimilar spare tire or wheel is
damaged, it should be replaced rather than
repaired.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
