TIRE CARE
Information About Uniform Tire
Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The 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 one
and one-half (11⁄2) 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 CWARNING
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.

Wheels and Tires
E142542
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.
Glossary of Tire Terminology
• Tire label: A label showing the OE
(Original Equipment) tire sizes,
recommended inflation pressure and
the maximum weight the vehicle can
carry.
• Tire Identification Number (TIN): A
number on the sidewall of each tire
providing information about the tire
brand and manufacturing plant, tire
size and date of manufacture. Also
referred to as DOT code.
• Inflation pressure: A measure of the
amount of air in a tire.
• Standard load: A class of P-metric or
Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5
bar) for Metric tires]. 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 41 psi [43 psi (2.9
bar) for Metric tires]. 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 inflation 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 mile (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 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.

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

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. Care
must be taken when changing the tire to
avoid damaging the sensor
It is recommended that you always have
your tires serviced by an authorized dealer.
The tire pressure should be checked
periodically (at least monthly) using an
accurate tire gauge, refer to Inflating your
tires in this chapter. Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. 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. Visit
www.checkmytires.org for additional
information.
When your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the tire
pressure monitoring 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 functionality of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When you Believe your System is not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. Please refer to
the following chart for information
concerning your tire pressure monitoring
system:

When Inflating your Tires
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires. It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure

Wheels and Tires
How Temperature Affects your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase approximately 2 to 4 psi (14
to 28 kPa) from a cold start situation. If
the vehicle is stationary overnight with the
outside temperature significantly lower
than the daytime temperature, the tire
pressure may decrease approximately 3
psi (21 kPa) for a drop of 30°F (17°C) in
ambient temperature. This lower pressure
value may be detected by the TPMS as
being significantly lower than the
recommended inflation pressure and
activate the TPMS warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check
air pressure in the road tires. If any tire is
under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNINGS
The use of tire sealants may damage
your tire pressure monitoring system
and should not be used. However, if
you must use a sealant, the tire pressure
monitoring system sensor and valve stem
on the wheel must be replaced by an
authorized Ford dealer.
See Tire Pressure Monitoring
System (page 257). for important
information. If the tire pressure
monitor sensor becomes damaged, it will
no longer function.
Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full functionality
of the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire while driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
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 257). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the 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:
