2020 FORD F-550 tire type

Inflating Your Tires
Safe operation of your vehicle
requires that your tires are
properly inflated. Remember that
a tire can lose up to half of its air
pressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to
check pressure of all tires and
adjust if required.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge (including spare, if
equipped). Inflate all tires to the
inflation pressure recommended
by Ford Motor Company.
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
the manufacturer ’s recommended
cold inflation pressure which can
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-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. The cold inflation
pressure should never be set lower
than the recommended pressure
on the Safety Compliance
Certification Label or Tire Label.
When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of 1
psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your
tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note:
If you are checking tire
pressure when the tire is hot, (for
example, driven more than 1 mile
[1.6 kilometers]), never bleed or
reduce air pressure. The tires are
hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.

Note:
If you have to drive a
distance to get air for your tire(s),
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the air pressure inside to go
up as you drive.
2. Remove the cap from the valve
on one tire, then firmly press the
tire gauge onto the valve and
measure the pressure.
3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release
air by pressing on the metal stem
in the center of the valve. Then
recheck the pressure with your tire
gauge.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
Note: Some spare tires operate at
a higher inflation pressure than the
other tires. For T type mini-spare
tires, (see the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare
tires, see the Dissimilar spare wheel
and tire assembly information for
a description. Store and maintain
at the higher of the front and rear
inflation pressure as shown on the
Safety Compliance Certification
Label or Tire Label. 6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire and
cause an air leak.
7. Check the sidewalls to make
sure there are no gouges, cuts or
bulges.
Tire Inflation Information
WARNING: An inflated tire
and rim can be very dangerous
if improperly used, serviced or
maintained. To reduce the risk
of serious injury, never attempt
to re-inflate a tire which has
been run flat or seriously
under-inflated without first
removing the tire from the wheel
assembly for inspection. Do not
attempt to add air to tires or
replace tires or wheels without
first taking precautions to
protect persons and property.
All tires with Steel Carcass Plies
(if equipped):
This type of tire utilizes steel cords
in the sidewalls. As such, they
cannot be treated like normal light
truck tires. Tire service, including
adjusting tire pressure, must be
performed by personnel trained,
supervised and equipped
according to Federal Occupational
Safety and Health Administration
regulations. For example, during
401
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Wheels and Tires

WARNING: You should
replace your spare tire when you
replace the road tires or after six
years due to aging even if it has
not been used.
U.S. DOT Tire Identification
Number
Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall.
This begins with the letters DOT
and indicates that the tire meets
all federal standards. The next
two numbers or letters are the
plant code designating where it
was manufactured, the next two
are the tire size code and the last
four numbers represent the week
and year the tire was built. For
example, the numbers 317 mean
the 31st week of 1997. After 2000
the numbers go to four digits. For
example, 2501 means the 25th
week of 2001. The numbers in
between are identification codes
used for traceability. This
information is used to contact
customers if a tire defect requires
a recall. Tire Replacement
Requirements
Your vehicle is equipped with tires
designed to provide a safe ride
and handling capability.
WARNING:
Only use
replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel
size may be found on either the
Safety Compliance Certification
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 the
Tire Label which is located on
the B-Pillar or edge of the
driver ’s door. If this information
is not found on these labels, then
you should contact your
authorized dealer as soon as
possible. 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.

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 109). 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 409). 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, 4WD
functionality may be limited. You may
experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
