TOWING A TRAILER
PRECAUTIONS
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING: Make sure that
the vertical load on the tow ball
is between the minimum and
maximum recommended weight
at all times. Failure to follow this
instruction could result in the
loss of control of your vehicle,
personal injury or death. WARNING:
Do not cut,
drill, weld or modify the trailer
hitch. Modifying the trailer hitch
could reduce the hitch rating. WARNING:
The anti-lock
brake system does not control
the trailer brakes.
TOWING A TRAILER
LIMITATIONS
The vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Note: Your vehicle could have
reduced performance when
operating at high altitudes and
when heavily loaded or towing a
trailer. When driving at elevation,
to match driving performance as
perceived at sea level, reduce gross
vehicle weight and gross
combination weight by 2% per
1,000 ft (300 m)
elevation.
LOADING YOUR TRAILER
To help minimize how trailer
movement affects your vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.

Traction AA A B C
WARNING: The traction
grade assigned to this tire is
based on straight-ahead braking
traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction
characteristics.
The traction grades, from highest
to lowest are AA, A, B, and C. The
grades represent the tire ’s ability
to stop on wet pavement as
measured under controlled
conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING:
The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
The temperature grades are A
(the highest), B and C,
representing the tire ’s resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the
material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden
tire failure. The grade C
corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety
Standard No. 139. Grades B and A
represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law.
INFORMATION ON THE TIRE
SIDEWALL
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.

*Treadwear: The treadwear
grade is a comparative rating
based on the wear rate of the tire
when tested under controlled
conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half times as
well on the government course as
a tire graded 100.
*
Traction: The traction grades,
from highest to lowest are AA, A,
B, and C. The grades represent the
tire's ability to stop on wet
pavement as measured under
controlled conditions on specified
government test surfaces of

Temperature: The temperature
grades are A (the highest), B and
C, representing the tire's
resistance to the generation of
heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
M. Maximum Inflation
Pressure:
Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle 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 which is
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 vehicle label.

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.

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.
