Tire change procedure
WARNING: 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).
WARNING: To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other side and
end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING: Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
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. Roadside Emergencies

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.
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. 1 2Roadside Emergencies
