CHANGING THE TIRES
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.
Note: If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
to Tire pressure monitoring system (TPMS) in the Tires, Wheels and
Loading chapter. 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 TPMS sensor for damage.Roadside Emergencies

• Exceed 70 mph (113 km/h)
• Use more than one dissimilar spare tire/wheel at a time
• Use commercial car washing equipment
• Use snow chains on the end of the vehicle with the dissimilar spare
tire/wheel
The usage of a full-size dissimilar spare tire/wheel can lead to
impairment of the following:
• Handling, stability and braking performance
• Comfort and noise
• Ground clearance and parking at curbs
• Winter weather driving capability
• Wet weather driving capability
• All-Wheel driving capability (if applicable)

1. Turn engine off and block the
wheel that is diagonally opposite of
the flat tire using the wheel chock,
if equipped. If the vehicle is a
4x4, lock the manual hub on the
wheel.
2. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
3. Use the tip of the lug wrench to remove any wheel trim.
4. Loosen each wheel lug nut one-half turn counterclockwise but do not
remove them until the wheel is raised off the ground.
The following steps apply to F–250/F–350 Single Rear Wheel
(SRW) vehicles only:
5. Insert the hooked end of the jack
handle into the jack and use the
handle to slide the jack under the
vehicle.
6. Position the jack according to the
following guides:

19. Stow the flat tire. Refer to Stowing the flat/spare tire if the vehicle
is equipped with a spare tire carrier.
20. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
21. Unblock the wheels.
The following step applies to F–250/F–350 Single Rear Wheel
(SRW) vehicles only:
22. When installing the wheel center
ornaments, ensure that the
ornament retention towers on the
back side of the ornament are
aligned with the studs/lug nuts. The
retention towers are designed to be
installed over the studs/nuts and
retain to the flange on the lug nut. Roadside Emergencies

If the ornament retention towers are
aligned between the studs/lug nuts,
the ornament is improperly
installed. This improper installation
may appear and sound correct, but
will not keep the ornament on the
vehicle. Ornaments improperly
installed in this manner will fall off
or become loose with minimal force
or impact.
Installing dual rear wheel ornaments
1. Align the ornament with the lug
nuts.
• (1) is the clip and (2) is the
flange.
2. Hold the ornament so that all of
the retention clips are sitting on the
flange of the lug nuts.
3. Use your hand or rubber mallet to
tap the ornament in a star pattern.
There should be an even gap
between the ornament and the
wheel. 1 2Roadside Emergencies

4. Be sure to install all the clips on the nuts over the flanges so that
there is an even gap all around and the retention clips are fully seated.
Stowing the flat/spare tire
Note: Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
If you are stowing a tire that requires reattaching it to the
vehicle with a tether, perform these steps first, then proceed with
the steps following.
1. Place the tire on end with the
valve stem facing toward the front
of the vehicle.
2. Place the tether into the bolt
holes in the wheel and attach the
lug nut using the lug winch.
3. Lay the tire on the ground with the valve stem facing in the direction
specified on the tire changing instructions located with the jack and
tools. Roadside Emergencies

4. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
5. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your authorized
dealer for assistance at your earliest convenience.
6. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
7. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, per scheduled maintenance information),
or at any time that the spare tire is disturbed through service of other
components.
8. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key (if equipped) and jack handle.

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that the vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Ford Motor Company has not
approved a slingbelt towing procedure.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground and the rear wheels off the ground using a wheel lift
On 4x4 vehicles, it is recommended that your vehicle be towed using
flatbed equipment with all the wheels off the ground. However, a wheel
lift may be used to lift the rear of the vehicle so long as, depending on
vehicle configurations, the following preparations are met:
• On Electronic Shift-On-the-Fly (ESOF) vehicles, the 4x4 control is
turned to the 2WD position prior to towing.
• On manual-shift transfer case vehicles, the front wheel hub locks are
in the FREE position prior to towing. Roadside Emergencies
