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.

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 (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 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.

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 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.

WARNINGS
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. Additionally 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. 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:
1. Make sure that you have the correct
tire and wheel size.
2. Lubricate the tire bead and wheel
bead seat area again.
3. Stand at a minimum of 12 feet (3.66
meters) away from the wheel and tire
assembly.
4. 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.
The use of wheels or tires not
recommended by Ford Motor
Company may affect the operation of
your tire pressure monitoring system.
If the TPMS indicator is flashing, your
TPMS is malfunctioning. Your
replacement tire might be
incompatible with your TPMS, or
some component of the TPMS may
be damaged.

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 298).
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: 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.
