FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS 2013 12.G Owners Manual

•Dual rear wheel (DRW) vehicle –
Six tire rotation
If your vehicle is equipped with dual
rear wheels it is recommended that
the front and rear tires (in pairs) be
rotated only side to side. We do not
recommend splitting up the dual
rear wheels. Rotate them side to
side as a set. After tire rotation,
inflation pressures must be adjusted
for the tires new positions in
accordance with vehicle
requirements.
Sometimes irregular tire wear can be corrected by rotating the tires.
USING SNOW CHAINS
WARNING:Snow tires must be the same size, load index, 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 vehicle
control, vehicle rollover, personal injury and death. Additionally, the use
of non-recommended tires and wheels could cause steering, suspension,
axle or transfer case/power transfer unit failure.
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 chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
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.

Follow these guidelines when using snow tires and chains:
•If possible, avoid fully loading your vehicle.
•Use only SAE Class S chains.
•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 tire chains when they are no longer needed. Do not use
tire chains on dry roads.
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.
Dissimilar Spare Tire and Wheel 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 tire and wheel assembly , 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 tire and wheel
assembly that is the same size and type as the road tires and wheels that
were originally provided by Ford. If the dissimilar spare tire or wheel is
damaged, it should be replaced rather than repaired.
A dissimilar spare tire and wheel assembly is defined as a spare tire or
wheel that is different in brand, size or appearance from the road tires
and wheels and can be one of three types:
1.T-type mini-spare:This spare tire begins with the letter “T” for tire
size and may have “Temporary Use Only” molded in the sidewall
2.Full-size dissimilar spare with label on wheel:This spare tire has
a label on the wheel that states: “THIS TIRE AND WHEEL FOR
TEMPORARY USE ONLY”
When driving with one of the dissimilar spare tires listed above,do not:
•Exceed 50 mph (80 km/h)
•Load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label

•Tow a trailer
•Use snow chains on the end of the vehicle with the dissimilar spare
tire
•Use more than one dissimilar spare tire at a time
•Use commercial car washing equipment
•Try to repair the dissimilar spare tire
Use of one of the dissimilar spare tires listed above at any one wheel
location 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)
3.Full-size dissimilar spare without label on wheel
When driving with the full-size dissimilar spare tire and wheel assembly,
do not:
•Exceed 70 mph (113 km/h)
•Use more than one dissimilar spare tire and wheel at a time
•Use commercial car washing equipment
•Use snow chains on the end of the vehicle with the dissimilar spare
tire and wheel
The usage of a full-size dissimilar spare tire and wheel assembly 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)
•Load leveling adjustment (if applicable)

When driving with the full-size dissimilar spare tire and wheel assembly,
additional caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire and wheel,
and seek service as soon as possible.
Tire Change Procedure
WARNING:When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission selector lever is in
positionP.
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission selector lever in
positionP, set the parking brake and block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
WARNING:Never get underneath a vehicle that is supported
only by a jack. 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.
WARNING:Always use the jack provided as original equipment
with your vehicle. If using a jack other than the one provided as
original equipment with your vehicle, make sure the jack capacity is
adequate for the vehicle weight, including any vehicle cargo or
modifications.

1. Park on a level surface.
2. Activate the warning flashers.
3. Place the transmission selector lever in positionP.
4. Apply the parking brake and turn engine off.
5. Block the wheel that is diagonally
opposite the tire you are changing.
The parking brake is on the transmission. Therefore, the vehicle will not
be prevented from moving when a rear wheel is lifted, even if the
parking brake is applied. Be sure to block both directions of the wheel
that is diagonally opposite to the wheel that is being lifted.
6. Remove the spare tire and jack from the storage location.
7. Loosen the wheel nut by pulling up on the handle of the lug nut
wrench about one-half turn (counterclockwise). Do not remove the
wheel lug nuts until you raise the tire off the ground.
8. Position the jack to raise the front or rear wheel. Raise the vehicle
with the jack applied to the axle(s).
Note:Never use the rear differential as a jacking point.
9. Raise the vehicle until the wheel is completely off the ground.
10. Remove the lug nuts with the lug nut wrench.
11. Replace the flat tire with the spare tire.
12. Use the lug nut wrench to
screw the lug nut snugly against the
wheel.
13. Lower the vehicle.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Ensure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 100 miles (160 km), and again at 500 miles
(800 km) of new vehicle operation and after any wheel disturbance (tire
rotation, changing a flat tire, wheel removal, etc.).

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
On all two-piece flat wheel nuts, apply one drop of motor oil between the
flat washer and the nut. Do not apply motor oil to the wheel nut threads
or the wheel stud threads.
