2016 LINCOLN MKX tire size

*Standard load: A class of P-metric or
Metric tires designed to carry a
maximum load at set pressure. For
example: for P-metric tires
35 psi
(2.4 bar) or 36 psi (2.5 bar) depending
on tire size and for Metric tires 36 psi
(2.5 bar). Increasing the inflation
pressure beyond this pressure will not
increase the tire ’s load-carrying
capability.
*
Extra load: A class of P-metric or Metric
tires designed to carry a heavier
maximum load at
42 psi (2.9 bar).
Increasing the inflation pressure beyond
this pressure will not increase the tire ’s
load-carrying capability.
*
kPa: Kilopascal, a metric unit of air
pressure.
*PSI: Pounds per square inch, a standard
unit of air pressure.
*
Cold tire pressure: The tire pressure
when the vehicle has been stationary
and out of direct sunlight for an hour or
more and prior to the vehicle being
driven for 1 mile (1.6 kilometers). *
Recommended inflation pressure: The
cold inflation pressure 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
located on the B-Pillar or the edge of the
driver’ s door.
*
B-pillar: The structural member at the
side of the vehicle behind the front door.
*
Bead area of the tire: Area of the tire
next to the rim.
*
Sidewall of the tire: Area between the
bead area and the tread.
*
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. Information Contained 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.

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 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! 351
MKX (CD9) Canada/United States of America, enUSA, ASO/OGC Review Wheels and Tires

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 section. 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 section. 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
When the tread is worn down to one
sixteenth of an inch (2 millimeters), 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 millimeters).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.
353
MKX (CD9) Canada/United States of America, enUSA, ASO/OGC Review Wheels and TiresE142546

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 (such as 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.
WARNINGS
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 WARNINGS
of loss of vehicle control, vehicle
rollover, personal injury and death.
Additionally 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. 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.
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: WARNINGS
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 feet (3.66
meters) away from the wheel and tire
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20
psi (1.38 bar) greater than the maximum
pressure, an authorized dealer or other
tire service professional should do the
mounting.
Always inflate steel carcass tires with a
remote air fill with the person inflating
standing at a minimum of 12 feet (3.66
meters) away from the wheel and tire
assembly. 355
