2021 FORD F-150 tire size

•
Stand at a minimum of 12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair if
the worn tires still have usable
depth.
To avoid potential Four-Wheel
Drive (4WD) malfunction or
(4WD) system damage, it is
recommended to replace all four
tires rather than mixing
significantly worn tires with new
tires.
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
The use of wheels or tires not
recommended may affect the
operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, your
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged. USING SNOW CHAINS WARNING: Do not exceed 30 mph
(50 km/h)
. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING: If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load
range as the original tires listed on the
tire placard, and they must be installed
on all four wheels. Mixing tires of
different size or construction on your
vehicle can adversely affect your
vehicle's handling and braking, and may
lead to loss of vehicle control. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel
can affect the safety and performance
of your vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the recommended tire inflation
pressures found on the Safety
Compliance Certification label, or the
Tire Label on the B-Pillar or the edge of
the driver door. Failure to follow this
instruction could result in loss of vehicle
control, vehicle rollover, or personal injury
or death.

• 265/70R17
• LT265/70R17
• 265/60R18
• LT265/70R18
We recommend you use steel wheels of
the same size and specification if snow
chains are required because chains may
chip aluminum wheels.
Follow these guidelines when using snow
tires and traction devices: •
If possible, avoid fully loading your
vehicle.
• Purchase snow chains from a
manufacturer that clearly labels body
to tire dimension restrictions.
• When driving with snow chains do not
exceed 30 mph (50 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Drive cautiously. If you hear the snow
chains rub or bang against the vehicle,
stop and tighten them. If this does not
work, remove the snow chains to
prevent vehicle damage.
• Remove the snow chains when they
are no longer needed. Do not use snow
chains on dry roads.
• If a temporary spare wheel is mounted
on your vehicle, do not use snow chains
on the axle with the temporary spare
wheel. Use snow chains that fit against the
sidewall of the tire to prevent the chains
from touching the wheel rims or
suspension. Refer to the previous
illustration.
If you have any questions regarding snow
chains, please contact your authorized
dealer.

USING BEAD-LOCK WHEELS -
RAPTOR
Your vehicle comes with unique wheels
matched to the tires. To avoid damage to
your wheels:
•
Maintain proper tire pressure.
• Due to extreme tire and wheel width,
do not take your vehicle through an
automatic car wash that uses
mechanical tracks, as wheel damage
may result.
• When installing wheels, always torque
lug nuts to specification with a torque
wrench.
• Inspect your wheels for damage on a
regular basis. If you have a damaged
wheel, replace it immediately.
• If you encounter an abnormally harsh
impact, inspect the outside tire wall of
your wheels, both inside and out, for
damage.
Note: Ford Performance only recommends
using bead-lock rings from Ford
Performance Parts, in conjunction with the
original equipment manufacturer (OEM)
tire. Any other combination using this wheel
could result in air loss or tire failure.
Note: Converting the bead-lock compatible
wheel to true bead-locks is for off-road use
only. We do not approve of the use of true
bead-locks for on-road driving.
If your vehicles equipped with the optional
bead lock compatible wheel, you can
convert this wheel to use a true bead-lock
ring, which allows operation at low tire
pressures when off-road to minimize the
risk of de-beading the tire. See your local
Ford Performance Parts Dealer for more
information. Tire Care WARNING: Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door. WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death. WARNING:
Replace the wheels
and tires with the exact original brand,
size and construction that came
originally on your vehicle. Use of any
other wheel or tire combinations, even
with identical size ratings, may result in
insufficient running clearances, tire
rubbing and eventual puncture. Failure
to follow tire replacement
recommendations can lead to tire failure,
loss of vehicle control, serious injury or
death.
Note: If you have reduced your tire pressure
for off-road use, the tire pressure monitoring
system (TPMS) warning light then activates
in the instrument panel as a reminder to
re-inflate the tires before returning to the
road.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Wheel and Tire Information

Your vehicle comes with high performance,
all-terrain tires designed to optimize
handling, steering and braking to provide
the performance you expect in a Ford
Performance vehicle. These tires are
optimized for both on and off-road
performance, and their ride, noise and wear
characteristics are different from other
tires. Also, because of their aggressive
tread profile, it is important that you
maintain your tires properly.
•
Always maintain your tire pressures
according to the tire information
placard located on the driver ’s door
B-pillar, using an accurate gauge.
Remember to be prepared to re-inflate
your tires before returning to the road.
If a tire filling station is not available,
remember to prepare a supplemental
means to inflate the tires, such as a
portable compressor.
• Check and set the tire pressures when
the tires are cold, and not warm from
driving. Wait at least three hours after
parking the vehicle before checking tire
pressure. Do not reduce the pressure
of warm tires.
• Check your tire pressure often to
maintain it properly. Tire pressure can
decrease over time and fluctuate with
temperature.
• Do not overload your vehicle.
Maximum vehicle and axle weights are
on the tire information placard.
• Use extra caution when operating the
vehicle near its maximum load,
including assuring proper tire pressure
and reducing speeds.
• If you encounter an abnormally harsh
impact, inspect your tires for damage.
• Inspect your tires for damage on a
regular basis. Replace a damaged tire
immediately. •
We do not approve the use of snow
chains on your vehicle's tires.
• Proper suspension alignment is critical
for maximum performance and
optimal tire wear. If you notice uneven
tire wear, have your alignment checked.
Spare Tire and Wheel
Your vehicle comes with a full size
matching spare with an all-terrain tire. The
spare tire and wheel assembly has the
same capability as the road tire and wheel
assemblies but does not come with a tire
pressure monitoring sensor. Wheels

CHECKING THE TIRE
PRESSURES
Safe operation of your vehicle
requires that your tires are
properly inflated. Every day before
you drive, check your tires.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge. Inflate all tires to the
recommended inflation pressure.
See Inflating the Tires (page
555).
INFLATING THE TIRES 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! WARNING:
Do not use the
tire pressure displayed in the
information display as a tire
pressure gauge. Failure to follow
this instruction could result in
personal injury or death.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Inflate your tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. You can find the
tire label with the recommended
tire inflation pressure next to the
tire size on the B-Pillar or the edge
of the driver door.
The recommended tire inflation
pressure is also 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 on the B-pillar, or on
the edge of the driver door.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's
tire pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function. 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! 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. 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.

CHANGING A FLAT TIRE
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.
Have a flat serviced by an authorized
dealer to prevent damage to the system
sensors. See Tire Pressure Monitoring
System Precautions (page 560). Replace
the spare tire with a road tire as soon as
possible. When repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Note: The use of tire sealant could damage
your tire pressure monitoring system. Only
use in roadside emergencies.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, you must mount all
road wheels that come with tire pressure
monitoring sensors on this vehicle.
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, the intent of the spare wheel is for
temporary use only. This means that if you
need to use it, 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 originally
provided by Ford. We define a dissimilar spare wheel and tire
assembly 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.
Engage any four-wheel drive mode. See
Four-Wheel Drive Limitations (page 292).
The usage of a full-size dissimilar spare
wheel and tire 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.
• Four-wheel drive capability.
When driving with the full-size dissimilar
spare wheel and tire assembly, give
additional caution to:
• Towing a trailer.
• Driving vehicles that come with a
camper body.
