flat tire LINCOLN MKZ 2013 Owner's Manual

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 (1
½) times as well on the government
course as a tire graded 100. The
relative performance of tires 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.

H: Indicates the tire's speed rating.
The speed rating denotes the speed
at which a tire is designed to be driven
for extended periods of time under a
standard condition of load and
inflation pressure. The tires on your
vehicle may operate at different
conditions for load and inflation
pressure. These speed ratings may
need to be adjusted for the difference
in conditions. The ratings range from
81 mph (130 km/h) to 186 mph (299
km/h). These ratings are listed in the
following chart.

Location of the Tire Label
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
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.
312
Wheels and Tires

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 (7 kPa) 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, (i.e. driven more
than 1 mile [1.6 kilometers]), 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.
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 (refer
to 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 (refer to 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.

Age
WARNING
Tires degrade over time
depending on many factors such
as weather, storage conditions, and
conditions of use (load, speed,
inflation pressure, etc.) 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 (TIN)
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.
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.

WARNINGS
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. 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. 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:
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. WARNINGS
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.
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.
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 by Ford Motor
Company may affect the operation of
your tire pressure monitoring system.
If the TPMS indicator is flashing, your
TPMS is malfunctioning. Your
replacement tire might be
incompatible with your TPMS, or
some component of the TPMS may
be damaged.

Safety Practices
WARNINGS
If your vehicle is stuck in snow,
mud, sand, etc., 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. Do not spin the wheels at over
35 mph (56 km/h). The tires may
fail and injure a passenger or
bystander. Driving habits have a great deal to do
with your tire mileage and safety.
•
Observe posted speed limits
• Avoid fast starts, stops and turns
• Avoid potholes and objects on the
road
• Do not run over curbs or hit the tire
against a curb when parking
Highway Hazards
No matter how carefully you drive
there ’s always the possibility that you
may eventually have a flat tire on the
highway. Drive slowly to the closest
safe area out of traffic. This may
further damage the flat tire, but your
safety is more important. 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 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’re driving, the wheels may 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.
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.
