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.
Spare tire information
Your vehicle may be equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire may be used on the
spare.

If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Such a tire could
result in damage to driveline components and make the vehicle
difficult to control.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire (pick-up
trucks only)Under the vehicle, just forward of the rear
bumper
Jack Regular cab, crew cab and SuperCab without
rear bench seat: Fastened to floor pan behind
rearmost seat on passenger side
SuperCab with rear bench seat: Under rear
bench on passenger side
Jack handle and lug
wrenchOn top of the radiator support at the front of
the engine compartment
Removing the spare tire (with spare tire carrier only)
1. The following tools are required to remove the spare tire:
•one handle extension and one
typical extension. To assemble,
align button with hole and slide
parts together. To disconnect,
depress button and pull apart.
•one wheel nut wrench. Slide over

2. The following steps are required to move the support bracket (if
equipped) away from the spare tire:
•With tapered end of lug wrench,
loosen the eyebolt on the support
bracket.
•Line up the eyebolt with the slot
in the support bracket.
•Slide the support bracket off the
eyebolt and move the support
bracket away from the spare tire.
3. Insert the hooked end of the jack
handle into the rear bumper
opening.
The handle will stop moving and
you will feel forward resistance to
turning when properly engaged.
4. Turn the handle counterclockwise
and lower the spare until you can
slide the tire rearward and the cable
is slack.
5. Remove the retainer through the center of the wheel.
Stowing the spare
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its original
position underneath the vehicle. The
effort to turn the jack handle
increases significantly and the spare
tire carrier ratchets when the tire is
raised to the stowed position. The spare tire carrier has a built-in ratchet
feature that will not allow you to overtighten.
4. Check that the tire lies flat to the frame assembly. Push against the
tire to make sure it is tightly seated under the vehicle. Loosen or
retighten if necessary.

5. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
When one of the rear
wheels is off the ground,
the transmission alone will not
prevent the vehicle from moving
or slipping off the jack, even if the
transmission is in P (Park)
(automatic transmission) or R
(Reverse) (manual transmission).
To prevent the vehicle from
moving when you change the tire,
be sure that the parking brake is
set and the diagonally opposite
wheel is blocked.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
The following steps apply to F250/F350 only:
6. Insert the hooked end of the jack
handle into the jack and use the

until the wheel is completely off the
ground and high enough to install
the spare tire.

wrench.

replace the flat tire with the spare
tire, making sure the valve stem is
facing outward for all front tires and
vehicles equipped with single rear
wheels. If replacing an inboard rear
tire on a dual rear wheel vehicle,
the valve stem must be facing outward. If replacing the outboard wheel,
the valve stem must be facing inward. Reinstall the lug nuts until the
wheel is snug against the hub. Do not fully tighten the lug nuts until the
wheel has been lowered.
11. Lower the wheel by turning the jack handle counterclockwise.
