2020 LINCOLN MKZ flat tire

depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
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.

•
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) 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
1.0 mi (1.6 km). •
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.

L.
Treadwear, Traction and
Temperature Grades: •
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 asphalt and concrete.
A tire marked C may have poor
traction performance.
• 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

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
342
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

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!
Always inflate your tires to the Ford
recommended inflation pressure even
if it is less than the maximum inflation
pressure information found on the tire.
The Ford recommended tire inflation
pressure is 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. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles Maximum Inflation Pressure is the tire
manufacturer's maximum permissible
pressure and the pressure at which the
maximum load can be carried by the tire.
This pressure is normally higher than the
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 Safety Compliance Certification
Label or Tire Label.
When weather temperature changes
occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop
can cause a corresponding drop of 1 psi
(0.07 bar)
in inflation pressure. Check
your tire pressures frequently and adjust
them to the proper pressure which can
be found on the Safety Compliance
Certification Label or Tire Label. To check the pressure in your tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note: If you are checking tire pressure
when the tire is hot, (for example driven
more than
1.0 mi (1.6 km), never bleed
or reduce air pressure. The tires are hot
from driving and it is normal for
pressures to increase above
recommended cold pressures. A hot tire
at or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to
get air for your tire(s), check and record
the tire pressure first and add the
appropriate air pressure when you get
to the pump. It is normal for tires to heat
up and the air pressure inside to go up
as you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire
gauge onto the valve and measure
the pressure.
343
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

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:
