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. 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

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.
Information on P Type Tires
P215/65R15 95H is an example of
a tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.) A.
P: Indicates a tire, designated
by the Tire and Rim Association,
that may be used for service on
cars, sport utility vehicles,
minivans and light trucks. Note:
If
your tire size does not begin with
a letter this may mean it is
designated by either the European
Tire and Rim Technical
Organization or the Japan Tire
Manufacturing Association.
B. 215:
Indicates the nominal
width of the tire in millimeters
from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire.
C. 65:
Indicates the aspect ratio
which gives the tire's ratio of
height to width.
D. R:
Indicates a radial type tire.
E. 15:
Indicates the wheel or rim
diameter in inches. If you change
your wheel size, you will have to
purchase new tires to match the
new wheel diameter.
F. 95:
Indicates the tire's load
index. It is an index that relates to
how much weight a tire can carry.
You may find this information in
your owner ’s manual. If not,
contact a local tire dealer.
Note: You may not find this
information on all tires because it
is not required by federal law.

The tire suppliers may have
additional markings, notes or
warnings such as standard load
or radial tubeless.
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 driver
’s
side door opening.
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

WARNINGS
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 of loss of
vehicle control, vehicle rollover,
personal injury and death. 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: •
Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again.
• Stand at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
• 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.

Changing Tires With a Tire
Pressure Monitoring System
Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See Inflating Your Tires in this
chapter. Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information display.
See General Information (page 68). The
low tire pressure warning light will turn on
if the tire pressure is significantly low. Once
the light is illuminated, your tires are
under-inflated and need to be inflated to
the manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.

Note:
If you are not sure about the proper
tire inflation pressures, contact an
authorized dealer or service center. Your tires may require additional inflation
pressure for operation at speeds greater
than 165 mph (265 km/h). If this label is
present on your vehicle, you must adjust
the tire pressure accordingly.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING
When you install a wheel, always remove any corrosion, dirt or foreign materials
present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle
is in motion, resulting in loss of vehicle control, personal injury or death. Ib-ft (Nm)
