risk of serious injury, when
mounting replacement tires and
wheels, you should not exceed
the maximum pressure indicated
on the sidewall of the tire to set
the beads without additional
precautions listed below. If the
beads do not seat at the
maximum pressure indicated,
re-lubricate and try again.
WARNING: When inflating
the tire for mounting pressures
up to 20 psi (1.38 bar) greater
than the maximum pressure on
the tire sidewall, the following
precautions must be taken to
protect the person mounting the
tire:

• Stand at a minimum of 12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection.
WARNING: For a mounting
pressure more than 20 psi
(1.38 bar) greater than the
maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting.
WARNING: Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of 12 ft
(3.66 m) away from the wheel
and tire assembly.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair.
Replacing a Tire That is
Greenhouse Gas Certified
The tires installed on this vehicle
at the factory as original
equipment are certified for
Greenhouse Gas and Fuel
Efficiency regulations.
Replacement tires must be of
equal or lower rolling resistance
level (TRRL or Crr). Consult with
your tire supplier(s) for
appropriate replacement tires.

Wheels and Tires

Sometimes irregular tire wear can
be corrected by rotating the tires.
USING SNOW CHAINS
WARNING: Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel
can affect the safety and performance
of your vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the recommended tire inflation
pressures found on the Safety
Compliance Certification label, or the
Tire Label on the B-Pillar or the edge of
the driver door. Failure to follow this
instruction could result in loss of vehicle
control, vehicle rollover, or personal injury
or death.
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.
Note:The suspension insulation and
bumpers help prevent vehicle damage. Do
not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.• 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 snow chains when they
are no longer needed. Do not use snow
chains on dry roads.
Please contact your upfitter for approved
snow chain types/sizes and other
recommendations for snow chain use.
CHANGING A ROAD WHEEL
If you get a flat tire while 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.
Tire Change Procedure
WARNING: Do not work on your
vehicle when the jack is the only support
as your vehicle could slip off the jack.
Failure to follow this instruction could
result in personal injury or death.
WARNING: To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel.
WARNING: Do not get under a
vehicle that is supported by a jack.
