TIRE REPLACEMENT
REQUIREMENTS
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.

2021 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202101, First-Printing Wheel and Tire Information

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. WARNING: 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. WARNING: 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. WARNING:
Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly. WARNING:
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:
• Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again.
82
2021 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202101, First-Printing Wheel and Tire Information

•
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.
If a four tire rotation is being
followed, it is recommended that
both front tires or both rear tires
generally be replaced as a pair if
the two remaining worn tires still
have usable tread depth. If a five
tire rotation is being followed and
the fifth tire is used to replace a
single unrepairable tire, a four tire
rotation should be followed with
the undamaged tires. Any
replacement for the damaged tire
should be used as a dedicated
spare until the remaining tires are
replaced as a set.
To avoid potential Four-Wheel
Drive (4WD) malfunction or
(4WD) system damage, it is
recommended to replace all tires
used in the tire rotation 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.
Only use snow chains on rear wheels.
Install snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire sizes:

CHECKING THE TIRE
PRESSURES
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 the 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 the manufacturer.
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!
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Always inflate your tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. You will find a
Tire Label containing the
manufacturer's recommended tire
inflation pressure by the tire size
and other important information
located 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.

Highway Hazards
No matter how carefully you drive,
there is always the possibility that
you could eventually have a flat
tire on the highway. Drive slowly
to the closest safe area out of
traffic. This could 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 the 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 are
driving, the wheels could be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
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.
INSPECTING THE WHEEL
VALVE STEMS
Check the valve stems for holes,
cracks, or cuts that could permit
air leakage.
TIRE ROTATION
WARNING: If the tire label
shows different tire pressures for
the front and rear tires and the
vehicle has a tire pressure
monitoring system, then you
need to update the settings for
the system sensors. Always
perform the system reset
procedure after tire rotation. If
you do not reset the system, it
may not provide a low tire
pressure warning when
necessary.
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: 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.
For the best tire life, a five tire
rotation is recommended that
includes the matching spare tire
mounted on the back of the
vehicle. This rotation requires a
forced re-learning of your tire
pressure monitor system sensors
by your vehicle, and should be
performed by an authorized dealer
or a service center to ensure the
tire pressure monitor system will
provide proper warning at all
times. When performing the tire
rotation yourself, a four tire
rotation is recommended, without
using the spare tire in the rotation,
so that no tire pressure monitor
system sensor re-learn is required.
If a five tire rotation is performed
without a tire pressure monitor
system sensor re-learn, the
system may not provide a low tire
pressure warning when necessary.
Keep in mind that a spare tire that
is not used in the tire rotation
should only be used temporarily
in the event of a flat tire, not as a
permanent replacement. The
spare tire should always be
replaced if it exceeds 6 years of
age, regardless of whether it is
part of the tire rotation.
Rear-wheel drive vehicles and
four-wheel drive vehicles with four
tire rotation, front tires at left of
diagram.
Sometimes irregular tire wear can
be corrected by rotating the tires.

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 PRECAUTIONS 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. 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.
Note: The use of tire sealants can damage
the tire pressure monitoring system.
TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature drops
significantly, the tire pressure could
decrease and activate the low tire pressure
warning lamp.
The warning lamp could also illuminate
when you use a spare wheel, or tire sealant
from the inflator kit. Note:
Regularly checking the vehicle tire
pressures can reduce the possibility for the
warning lamp to illuminate due to outside
air temperature changes.
Note: After you inflate the tires to the
recommended pressure it could take up to
two minutes of driving over
20 mph
(32 km/h) for the warning indicator to turn
off.

CHANGING A FLAT TIRE
Note:
You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
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, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
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 in order to prevent damage to the
tire pressure monitoring system sensors.
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 tire pressure
monitoring system sensor for damage.
Tire Change Procedure WARNING: Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death. WARNING:
Do not get under a
vehicle that is only supported by a
vehicle jack. WARNING:
The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in
an emergency. WARNING: Check that the vehicle
jack is not damaged or deformed and
the thread is lubricated and clean. WARNING:
Do not work on your
vehicle when the jack is the only support
as your vehicle could slip off the jack.
Failure to follow this instruction could
result in personal injury or death. WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
