Important Information About Sport
Tires and Wheels
Vehicles equipped with the optional
265/40R21 tires are designed to
enhance performance. To continue
providing this performance, extra care
must be taken when operating and
maintaining your vehicle.
These low-profile high-performance tires
are designed to optimize the driving
dynamics you expect in a sport vehicle
in both dry and wet conditions. These
tires are not optimized for off-road or
winter (snow or cold weather)
performance; and their ride, noise, and
wear characteristics are different than
non-performance tires. With low-profile
tires, you may notice an increase in road
noise and faster wear, depending on
road conditions and driving habits. Also,
because of their lower profile, the tires
are more susceptible to road damage
from potholes, rough or unpaved roads,
car wash rails, and curb contact than
standard tires and wheels.
Note:
Your vehicle ’s warranty does not
cover these types of damages. Extra
caution should be taken when operating
on rough roads to avoid impacts that
could cause wheel and tire damage.
The optional 265/40R21 tires were
designed for track use and may exhibit
significantly reduced tread life and
increased tire noise compared to the
standard equipment tires under normal
driving conditions. Increasing the front
camber settings beyond the factory
settings may further accelerate tread
wear and induce tire noise.
Note: Do not use tire chains on your
vehicle ’s optional 265/40R21 tires and
wheels. The use of any type of tire chain
on these tires may damage your vehicle.
See Using Snow Chains (page 366). Notice to Crossover Vehicle Owners
Crossover vehicles handle differently
than passenger cars in the various
driving conditions that are encountered
on streets, highways and off-road.
Crossover vehicles are not designed for
cornering at speeds as high as
passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.

Crossover vehicles have a significantly
higher rollover rate than other types of
vehicles. To reduce this risk of serious
injury or death from a rollover or other
crash you must:
•
Avoid sharp turns and abrupt
maneuvers.
• Drive at safe speeds for the
conditions.
• Keep tires properly inflated.
• Never overload or improperly load
your vehicle.
• Make sure every passenger is
properly restrained. WARNING
In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a seatbelt. Information About Uniform Tire Quality
Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set. Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires Ford Motor
Company to give you the following
information about tire grades exactly as
the government has written it.
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 1 ½ times as well on the
government course as a tire graded 100.

Have a flat serviced by an authorized dealer
in order to prevent damage to the tire
pressure monitoring system sensors. See
Tire Pressure Monitoring System (page 367).
Replace the spare tire with a road tire as
soon as possible. During repairing or
replacing of the flat tire, have an authorized
dealer inspect the tire pressure monitoring
system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING
Failure to follow these guidelines could
result in an increased risk of loss of
vehicle control, injury or death. If you have a dissimilar spare wheel and tire,
then it is intended for temporary use only.
This means that if you need to use it, you
should replace it as soon as possible with a
road wheel and tire assembly that is the
same size and type as the road tires and
wheels that were originally provided by Ford.
If the dissimilar spare tire or wheel is
damaged, it should be replaced rather than
repaired.
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 and can be
one of three types:
1.
T-type mini-spare: This spare tire begins
with the letter T for tire size and may have
Temporary Use Only molded in the sidewall.
2.
Full-size dissimilar spare with label on
wheel: This spare tire has a label on the
wheel that states: THIS WHEEL AND TIRE
ASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar spare
tires listed above, do not: •
Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
• Use commercial car washing equipment.
• Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listed
above at any one wheel location can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability (if applicable).
3.
Full-size dissimilar spare without label
on wheel
372
MKX (CD9) Canada/United States of America, enUSA, First Printing Wheels and Tires
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed 70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use commercial car washing equipment.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability. When driving with the full-size dissimilar
spare wheel and tire assembly additional
caution should be given to:
•
Towing a trailer.
• Driving vehicles equipped with a camper
body.
• Driving vehicles with a load on the cargo
rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly and
seek service as soon as possible.
Tire Change Procedure
(If Equipped) WARNINGS
When one of the front wheels is off the
ground, the transmission alone will not
prevent the vehicle from moving or slipping
off the jack, even if the transmission is in park
(P). WARNINGS
To help prevent your vehicle from
moving when changing a wheel, shift
the transmission into park (P), set the parking
brake and use an appropriate block or wheel
chock to secure the wheel diagonally
opposite to the wheel being changed. For
example, when changing the front left wheel,
place an appropriate block or wheel chock
on the right rear wheel. No person should place any portion of
their body under a vehicle that is
supported by a jack. Do not attempt to change a tire on the
side of the vehicle close to moving
traffic. Pull far enough off the road to avoid
the danger of being hit when operating the
jack or changing the wheel. Always use the jack provided as
original equipment with your vehicle.
If using a jack other than the one provided,
make sure the jack capacity is adequate for
the vehicle weight, including any vehicle
cargo or modifications. If you are unsure if
the jack capacity is adequate, contact the
authorized dealer. 373
