*Tread area of the tire: Area of
the perimeter of the tire that
contacts the road when mounted
on the vehicle.
*Rim: The metal support (wheel)
for a tire or a tire and tube
assembly upon which the tire
beads are seated.
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.

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:
83
2021 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202101, First-Printing Wheel and Tire Information

•
255/70R16
•Only install chains that are 15 mm
or less.
• 255/75R17
•Only install chains that are 15 mm
or less.
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, see following illustration
above.
If you have any questions regarding snow
chains, please contact your authorized
dealer.

INSPECTING THE TIRE FOR
WEAR
When the tread is worn down to
one sixteenth of an inch (2 mm),
tires must be replaced to help
prevent your vehicle from skidding
and hydroplaning. Built-in
treadwear indicators, or wear bars,
which look like narrow strips of
smooth rubber across the tread
will appear on the tire when the
tread is worn down to one
sixteenth of an inch (2 mm).
When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
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. INSPECTING THE TIRE FOR
DAMAGE
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
dismounted and inspected in case
it needs to be repaired or replaced.
For your safety, tires that are
damaged or show signs of
excessive wear should not be used
because they are more likely to
blow out or fail.
Periodically inspect the tire treads
and sidewalls for damage, such
as bulges in the tread or sidewalls,
cracks in the tread groove and
separation in the tread or sidewall.
If damage is observed or
suspected, have the tire inspected
by a tire professional.
Safety Practices
WARNING: 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. WARNING:
Do not spin the
wheels at over 34 mph
(55 km/h). The tires may fail and
injure a passenger or bystander.

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.

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

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.
VIEWING THE TIRE
PRESSURES Using the information display
arrow keys navigate to the truck
info section where you can view
