2015 FORD F150 flat tire

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.
Inspecting Your Tires and
Wheel Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects such as stones,
nails or glass that may be wedged
in the tread grooves. Check the tire
and valve stems for holes, cracks,
or cuts that may permit air
leakage and repair or replace the
tire and replace the valve stem.
Inspect the tire sidewalls for
cracking, cuts, bruises and other
signs of damage or excessive
wear. If internal damage to the tire
is suspected, have the tire
demounted and inspected in case

Age
WARNING
Tires degrade over time
depending on many factors
such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives.
In general, tires should be
replaced after six years regardless
of tread wear. However, heat
caused by hot climates or
frequent high loading conditions
can accelerate the aging process
and may require tires to be
replaced more frequently.
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.
WARNINGS
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 or
the Tire Label. 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
340
F-150 (), enUSA, First Printing Wheels and Tires

WARNINGS
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. If you
have questions regarding tire
replacement, contact your
authorized dealer as soon as
possible. To reduce the risk of serious
injury, when mounting
replacement tires and wheels, you
should not exceed the maximum
pressure indicated on the sidewall
of the tire to set the beads without
additional precautions listed
below. If the beads do not seat at
the maximum pressure indicated,
re-lubricate and try again
When inflating the tire for
mounting pressures up to 20 psi
(1.38 bar) greater than the
maximum pressure on the tire
sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
1. Make sure that you have the
correct tire and wheel size.
2. Lubricate the tire bead and
wheel bead seat area again. WARNINGS
3. Stand at a minimum of 12 feet
(3.6 meters) away from the wheel
and tire assembly.
4. Use both eye and ear
protection.
For a mounting pressure more
than 20 psi (1.38 bar) greater than
the maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting.
Always inflate steel carcass tires
with a remote air fill with the
person inflating standing at a
minimum of 12 feet (3.6 meters)
away from the wheel and tire
assembly Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle
The two front tires or two rear tires
should generally be replaced as a
pair.
The tire pressure sensors mounted
in the wheels are not designed to
be used in aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor
Company may affect the
operation of your tire pressure
monitoring system.

If the tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud, or sand, do not
rapidly spin the tires; spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds. Do not spin the wheels at
over 35 mph (56 km/h). The
tires may fail and injure a
passenger or bystander. Driving habits have a great deal
to do with your tire mileage and
safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on
the road
*Do not run over curbs or hit the
tire against a curb when parking Highway Hazards
No matter how carefully you drive
there
’s always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect your tire or vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and
replace it with your spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you’re
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
342
F-150 (), enUSA, First Printing Wheels and Tires

Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
Tire Rotation
WARNING
If the tire label shows
different tire pressures for the
front and rear tires and the vehicle
is equipped with a tire pressure
monitoring system, then the
settings for the system sensors
need to be updated. Always
perform the system reset
procedure after tire rotation. If the
system is not reset, it may not
provide a low tire pressure
warning when necessary. See the
tire pressure monitoring system
reset procedure in this chapter. Note:
If your tires show uneven
wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation. Note:
Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. 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. If you have a dissimilar
spare wheel and tire assembly it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.
Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.
Rear-wheel drive vehicles and
four-wheel drive vehicles (front
tires at left of diagram) Sometimes irregular tire wear can
be corrected by rotating the tires.

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system
is not a substitute for manually
checking tire pressure. The tire
pressure should be checked periodically
(at least monthly) using a tire gauge, see
Inflating your tires in this chapter. Failure
to properly maintain your tire pressure
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.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle ’s handling and stopping ability. Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver
’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
The tire pressure monitoring system
complies with part 15 of the FCC rules and
with RSS-210 of Industry Canada.
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) This device
must accept any interference received,
including interference that may cause
undesired operation.

Changing Tires With a Tire
Pressure Monitoring System
Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See Inflating Your Tires in this
chapter. Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four 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, your tires are under-inflated
and need 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:
