Changing Tires With a Tire
Pressure Monitoring System
E142549
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 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.
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.
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. See 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
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
about 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 about 3 psi (21
kPa) for a drop of 30°F (17°C) in
ambient temperature. This lower
pressure value may be detected by
the tire pressure monitoring system
as being significantly lower than the
recommended inflation pressure and
activate the system 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 the air pressurein 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.
TIRE CARE
Important information for
245/40R19 low-profile tires
and wheels If your vehicle is
equipped with 245/40R19 tires,
they are low-profile tires. These
tires and wheels are designed to
give your vehicle a sport
appearance. With low-profile tires,
you may notice an increase in road
noise and faster tire wear,
depending on road conditions and
driving styles. Due to their design,
low-profile tires and wheels are
more prone 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 damage.
Tires should always be kept at the
correct inflation pressures and
extra caution should be taken when
operating on rough roads to avoid
impacts that could cause wheel
and tire damage.

Information About Uniform
Tire Quality Grading
E142542
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 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.
308
Wheels and Tires

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.
Glossary of Tire Terminology
•
Tire label: A label showing the
original equipment tire sizes,
recommended inflation
pressure and the maximum
weight the vehicle can carry.
• Tire Identification Number:
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.

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.
309
Wheels and Tires

•PSI: Pounds per square inch, a
standard unit of air pressure.
• Cold tire pressure: The tire
pressure when the vehicle has
been stationary and out of
