You will find a Tire Label containing tire
inflation pressure by tire size and other
important information located on the
B-Pillar or the edge of the driver’
s door.
Inflating Your Tires
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 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 Ford
Motor Company. You are strongly urged to buy a reliable
tire pressure gauge, as automatic
service station gauges may be
inaccurate. Ford recommends the use
of a digital or dial-type tire pressure
gauge rather than a stick-type tire
pressure gauge.
Use the recommended cold inflation
pressure for optimum tire performance
and wear. Under-inflation or
over-inflation may cause uneven
treadwear patterns
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

3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release air
by pressing on the metal stem in the
center of the valve. Then recheck the
pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
Note: Some spare tires operate at a
higher inflation pressure than the other
tires. For T type mini-spare tires, see the
Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare tires,
see the Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label. 6.
Visually inspect the tires to make
sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve
Stems
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. Check the tire and valve stems
for holes, cracks, or cuts that may permit
air leakage and repair or replace the tire
and replace the valve stem. 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 demounted 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. Improper or inadequate vehicle
maintenance can cause tires to wear
abnormally. Inspect all your tires,
including the spare, frequently, and
replace them if one or more of the
following conditions exist:
Tire Wear
344
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and TiresE142546

When the tread is worn down to 0.08 in
(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
0.08 in
(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.
Damage
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. Tires can be damaged
during off-road use, so inspection after
off-road use is also recommended. 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. WARNING:
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 U.S. 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: Replace the wheels
and tires with the exact original brand,
size and construction that came
originally on your vehicle. Use of any
other wheel or tire combinations, even
with identical size ratings, may result
in insufficient running clearances, tire
rubbing and eventual puncture. Failure
to follow tire replacement
recommendations can lead to tire
failure, loss of vehicle control, serious
injury or 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:
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:
1. Make sure that you have the correct
tire and wheel size.
2. Lubricate the tire bead and wheel
bead seat area again. 3. Stand at a minimum of
12 ft (3.66 m)
away from the wheel and tire
assembly.
4. Use both eye and ear protection. 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.
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.

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.
Front-wheel drive vehicles and those
with an independent rear suspension (if
equipped) may require alignment of all
four wheels.
The tires should also be balanced
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.
Tire Rotation
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:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. 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.
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.
Front-wheel drive and all-wheel drive
vehicles (front tires on the left side of
the diagram) All vehicles with directional tires (front
tires on the left of the diagram)
Sometimes irregular tire wear can be
corrected by rotating the tires.

USING SUMMER TIRES
Summer tires provide superior performance
on wet and dry roads. Summer tires do not
have the Mud and Snow (M+S or M/S) tire
traction rating on the tire side wall. Since
summer tires do not have the same traction
performance as All-season or Snow tires, we
do not recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear and
environmental conditions) or in snow and ice
conditions. Like any tire, summer tire
performance is affected by tire wear and
environmental conditions. If you must drive
in those conditions, we recommend using
Mud and Snow (M+S, M/S), All-season or
Snow tires.
Always store your summer tires indoors at
temperatures above
19°F (-7°C). The rubber
compounds used in these tires lose flexibility
and may develop surface cracks in the tread
area at temperatures below
19°F (-7°C). If the
tires have been subjected to 19°F (-7°C) or
less, warm them in a heated space to at least
41°F (5°C)
for at least 24 hours before
installing them on a vehicle, or moving the vehicle with the tires installed, or checking
tire inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply heat
or blow heated air directly on the tires.
Always inspect the tires after storage periods
and before use.
USING 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:
The use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case or power transfer unit failure. If you
have questions regarding tire replacement,
contact your authorized dealer as soon as
possible.
The tires on your vehicle may have
all-weather treads to provide traction in rain
and snow. However, in some climates you
may need to use snow chains.
Your vehicle may not be compatible with
snow chain or cable usage with the
factory-fitted wheels and tires. Only certain
chains or snow cables have been approved
by Lincoln as safe for use on your vehicle
with the following tire size: 225/55R17. You
should only install chains or cables sized at
10 mm or less in dimension as measured on
the sidewall of your tire. Not all S-class snow
chains meet these restrictions. Chains of this
size restriction will include a tensioning
349
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

device. The chains should be mounted in
pairs on the front tires only. If you need to
use chains, it is recommended that steel
wheels (of the same size and specification)
be used, as chains may chip aluminum
wheels.
Follow these guidelines when using traction
devices:
•
If possible, avoid fully loading your
vehicle
• Purchase chains or cables from a
manufacturer that clearly labels body to
tire dimension restrictions.
• When driving with snow chains or cables,
do not exceed 30 mph (48 km/h) or the
maximum speed recommended by the
chain manufacturer; whichever is less.
• Drive cautiously. If you hear the chains
or cables rub or bang against the vehicle,
stop and retighten them. If this does not
work, remove the chains or cables and
prevent vehicle damage. •
Remove the chains or cables when they
are no longer needed. Do not use the
chains or cables on dry roads.
• If a temporary spare tire is mounted on
your vehicle, do not use snow chains on
the axle with the temporary spare tire.
If you have any questions regarding snow
tires or snow chains, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM 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. Note:
You should only use tire sealants in
roadside emergencies as they could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function. 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
