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. Tire Replacement Requirements
Your vehicle is equipped with tires
designed to provide a safe ride and
handling capability.
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
444
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Wheel and Tire Information

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.
• 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.
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. Only install chains that
are 15mm or less (SAE Class S chains).
• 265/70R17
• 275/65R18
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:

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
449).
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.
INSPECTING THE TIRE FOR WEAR
449
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Tire CareE142546

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.
450
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Tire Care

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.
Rotating your tires at the recommended
interval will help your tires wear more
evenly, providing better tire performance
and longer tire life. Note:
If your tires show any uneven
wear have the alignment checked by
an authorized dealer before rotating
tires.
Note: 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.
Tire Rotation Diagram
Follow the diagram indicating the correct
tire locations for rotating the tires.
