2018 FORD F450 SUPER DUTY steering

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your
vehicle. If you change the diameter of the
tires from that fitted at the factory, the
speedometer may not display the correct
speed. Take your vehicle to an authorized
dealer to have the system reprogrammed.
If you intend to change the size of the
wheels from that fitted by the
manufacturer, you can check the suitability
with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 382).
The Ford recommended tire inflation
pressures can be found on the Tire Label,
which is located on the B-pillar or the edge
of the driver's door. This information can
also be found on the Safety Compliance
Certification Label (affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door last post;
next to the driver ’s seating position).
Ford strongly recommends maintaining
these tire pressures at all times. Failure to
follow the tire pressure recommendations
can cause uneven treadwear patterns,
reduced fuel economy, and adversely
affect the way your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least
once per month.
Set the pressure for your spare tire to the
highest value given for your vehicle and tire
size combination (if equipped). Notice to utility vehicle and truck
owners WARNINGS
Utility vehicles have a significantly
higher rollover rate than other types
of vehicles.
Vehicles with a higher center of
gravity (utility and four-wheel drive
vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury and
death. In a rollover crash, an unbelted
person is significantly more likely to
die than a person wearing a seatbelt.

Do not become overconfident in the
ability of four-wheel drive vehicles.
Although a four-wheel drive vehicle
may accelerate better than a two-wheel
drive vehicle in low traction situations, it
won't stop any faster than two-wheel drive
vehicles. Always drive at a safe speed.E145298

•
Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up
or damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up
or damaging underbody components.
All other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use. As a result of the above dimensional
differences, Sport utility vehicles and
trucks often will have a higher center of
gravity and a greater difference in center
of gravity between the loaded and
unloaded condition. These differences that
make your vehicle so versatile also make
it handle differently than an ordinary
passenger car.
TIRE CARE
Information About Uniform
Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires.
The Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example: Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set.

You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. Ford
recommends the use of a digital
or dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
WARNING
Under-inflation is the most
common cause of tire failures
and may result in severe tire
cracking, tread separation or
blowout, with unexpected loss of
vehicle control and increased risk
of injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat! Always inflate your tires to the
Ford recommended inflation
pressure even if it is less than the
maximum inflation pressure
information found on the tire. The
Ford recommended tire inflation
pressure is found on the Safety
Compliance Certification Label or Tire Label (affixed to either the
door hinge pillar, door-latch post,
or the door edge that meets the
door-latch post, next to the
driver's seating position), or Tire
Label located on the B-pillar or
the edge of the driver's door.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles.
Note:
Do not reduce tire pressure
to change the ride characteristics
of the vehicle. If you do not
maintain the inflation pressure at
the levels specified by Ford, your
vehicle may experience a condition
known as shimmy. Shimmy is a
severe vibration and oscillation in
the steering wheel after the vehicle
travels over a bump or dip in the
road that does not dampen out by
itself. Shimmy may result from
significant under-inflation of the
tires, improper tires (load range,
size, or type), or vehicle
modifications such as lift-kits. In
the event that your vehicle
experiences shimmy, you should
slowly reduce speed by either lifting
off the accelerator pedal or lightly
applying the brakes. The shimmy
will cease as the vehicle speed
decreases.
Maximum Inflation Pressure is
the tire manufacturer's maximum
permissible pressure and the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than

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, transfer
case or power transfer unit failure. Note:
Do not use snow chains on vehicles
with 20 inch wheels and tires.
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 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.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure Monitoring
System WARNING
The tire pressure monitoring system
is not a substitute for manually
checking tire pressures. You should
periodically check tire pressures using a
pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury. Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated
to the inflation pressure recommended by
the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If
your vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 114). Performing the
trailer setup process also resets the trailer
tire pressure monitoring system.
CHANGING A ROAD WHEEL WARNING
If the tire pressure monitor sensor
becomes damaged it may not
function.
Note:
If your vehicle is equipped with the
tire pressure monitoring system, the
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
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.
If your vehicle is equipped with the tire
pressure monitoring system, have a flat
serviced by an authorized dealer in order
to prevent damage to the system sensors.
See
Tire Pressure Monitoring System
(page 400). 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 system
sensor for damage. Dissimilar Spare Wheel and Tire
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 wheel and
tire, 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 wheel and tire 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 wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) in 4WD.
• Engage 4WD unless the vehicle is
stationary.
• Use 4WD on dry pavement.
