2018 FORD F-250 tire pressure

Understanding Your Tire Pressure
Monitoring System
Single Rear Wheel
Dual Rear Wheel The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. The low tire pressure warning light
will turn on if the tire pressure is
significantly low. Once the light is
illuminated, one or more of your tires are
under-inflated and needs to be inflated to
the manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

When Inflating Your Tires
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2 to 4 psi (14 to 28
kPa) from a cold start situation. If the
vehicle is stationary overnight with the
outside temperature significantly lower
than the daytime temperature, the tire
pressure may decrease about 3 psi (21
kPa) for a drop of 30°F (17°C) in ambient
temperature. This lower pressure value
may be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system warning
light for low tire pressure.
If the low tire pressure warning light is on,
visually check each tire to verify that no tire
is flat. If one or more tires are flat, repair as
necessary. Check the air pressure in the
road tires. If any tire is under-inflated,
carefully drive the vehicle to the nearest
location where air can be added to the
tires. Inflate all the tires to the
recommended inflation pressure.
Tire Pressure Monitoring System Reset
Procedure WARNING
To determine the required
pressure(s) for your vehicle, see the
Safety Compliance Certification
Label (on the door hinge pillar, door-latch
post or the door edge that meets the
door-latch post, next to the driver seat) or
the Tire Label on the B-Pillar or the edge
of the driver door. Note:
You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation.
To provide the vehicle's load carrying
capability, some vehicles require different
recommended tire pressures in the front
tires as compared to the rear tires. The tire
pressure monitoring system equipped on
these vehicles is designed to illuminate the
low tire pressure warning light at two
different pressures; one for the front tires
and one for the rear tires.
Since tires need to be rotated to provide
consistent performance and maximum tire
life, the tire pressure monitoring system
needs to know when the tires are rotated
to determine which set of tires are on the
front and which are on the rear. With this
information, the system can detect and
properly warn of low tire pressures.

Trailer Tire Pressure Monitoring
System (If Equipped)
Note: Additional equipment may be
required for your vehicle to support trailer
tire pressure monitoring. See your authorized
dealer for more information.
Note: The trailer tire pressure monitoring
system is not a substitute for proper tire
maintenance. It is your responsibility to
maintain correct tire pressures at all times.
Note: If a trailer tire is repaired, replaced or
broken down for service, the screw and valve
on the trailer tire pressure sensor should be
replaced. See your authorized dealer for
details. The trailer tire pressure monitoring system
is an added safety feature that allows you
to view your trailer tire pressures through
the information display. See
General
Information (page 113). Tire pressure
sensors are mounted into each tire on your
trailer. The sensors send a message to your
vehicle indicating the current trailer tire
pressure.
If the trailer tire pressure monitoring
system detects that a tire is low, a warning
message appears in the information
display. The trailer tire pressure status
screen in the information display highlights
the tire with a low pressure.
The main function of the trailer tire
pressure monitoring system is to warn you
when your trailer tires need air. It can also
warn you in the event the system is no
longer capable of functioning as intended.
See
Information Messages (page 129).
When a Temporary Spare or New Tire
is Installed
If you have replaced a trailer tire with a new
or spare tire, a warning message appears
and pressure readings are no longer
displayed for that tire.
To restore the full function of the trailer
tire pressure monitoring system:
• Have the damaged wheel and tire
assembly repaired and remounted to
your trailer.
• Install the trailer tire pressure
monitoring sensor into the new wheel
and tire assembly.
• Perform the trailer tire pressure
monitoring system reset procedure.
Trailer Tire Pressure Monitoring
System Reset Procedure
Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation, or when a new trailer tire
pressure sensor is installed into a trailer tire.

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 113). 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 illuminates 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 when 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.

2. Use an up-and-down motion with the
jack handle to raise the wheel
completely off the ground.
Note: Hydraulic jacks are equipped with a
pressure release valve that prevents lifting
loads which exceed the jack's rated
capacity.
3. Remove the lug nuts with the lug wrench.
4. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front an inboard rear
wheels. If you are 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.
5. Lower the wheel by slowly turning the release valve counterclockwise.
Opening the release valve slowly
provides a more controlled rate of
descent.
6. Remove the jack and fully tighten the lug nuts in the order shown. See
Technical Specifications (page 418).
7. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped
with a spare tire carrier.
8. Stow the jack, jack handle and lug wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.
9. Unblock the wheels. 8-lug nut torque sequence
