tire size LINCOLN NAUTILUS 2021 User Guide

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.
• 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 All-Wheel Drive (AWD)
malfunction or (AWD) 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.
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.

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:
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 the front wheels.
Install snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire size:
• 235/60R18 all season tires.
•Only use ultra low profile snow chains
that are 10 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.

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.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
Individual Tire Pressure Monitoring S
ystem
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:
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. 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.

CHANGING A FLAT TIRE
WARNING: If the tire pressure
monitor sensor becomes damaged it may
not function.
Note: The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies. If you must use a sealant, use
the Tire Mobility Kit sealant. Replace the tire
pressure monitoring system sensor and
valve stem on the wheel by an authorized
dealer after use of the sealant.
Note: The tire pressure monitoring system
indicator light will illuminate 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 while 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.
See
Tire Pressure Monitoring System Overview
(page 385). Replace the spare tire with a road
tire as soon as possible. During repairing or
replacing of the flat tire, have an authorized
dealer inspect the tire pressure monitoring
system sensor for damage.
