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.

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! 359
MKX (CD9) Canada/United States of America, enUSA, First Printing Wheels and Tires

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
(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, (for example, 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.
360
MKX (CD9) Canada/United States of America, enUSA, First Printing 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.

WARNINGS
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. 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 (136 kPa)
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. WARNINGS
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.
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.
The two front tires or two rear tires
should 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 tire pressure monitoring system
indicator is flashing, the system is
malfunctioning. Your replacement tire
might be incompatible with your tire
pressure monitoring system, or some
component of the system may be
damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in snow,
mud or sand, 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.
363
MKX (CD9) Canada/United States of America, enUSA, First Printing Wheels and Tires

WARNINGS
Do not spin the wheels at over
34 mph (55 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 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
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.
364
MKX (CD9) Canada/United States of America, enUSA, First Printing Wheels and Tires

Rotating your tires at the recommended
interval (as indicated in the scheduled
maintenance information) will help your
tires wear more evenly, providing better
tire performance and longer tire life.
Sometime irregular tire wear can be
corrected by rotating the tires.
Front-wheel drive and All-wheel drive
vehicles (front tires on the left side of
the diagram).
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 20ºF (-7ºC). The rubber
compounds used in these tires lose flexibility
and may develop surface cracks in the tread
area at temperatures below 20ºF (-7ºC). If
the tires have been subjected to 20ºF (-7ºC)
or less, warm them in a heated space to at
least 40ºF (5ºC) 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.
