Second Stage: Checking Tire Pressure
WARNINGS
If you are proceeding from the First
Stage: Re-inflating the Tire with Sealing
Compound and Air section and have injected
sealant in the tire and the pressure is below
20 psi (1.4 bar), continue to the next step. The power plug may get hot after use
and should be handled carefully while
unplugging. Check the air pressure of your tires as
follows:
1.
Remove the valve cap from the tire valve. 2. Firmly screw the air compressor hose
onto the valve stem by turning clockwise.
3. Push and turn the dial clockwise to the air position.
4. If required, turn on the compressor and adjust the tire to the recommended
inflation pressure shown on the tire label
located on the driver's door or door jamb
area. The tire pressure should be
checked with the compressor turned OFF
in order to get an accurate pressure
reading.
5. Unplug the hoses, re-install the valve cap
on the tire and return the kit to the
stowage area. What to do after the Tire has been
Sealed
After using the kit to seal your tire, you will
need to replace the sealant canister. Sealant
canisters and spare parts can be obtained
at an authorized Ford dealer. Empty sealant
canisters may be disposed of at home.
However, canisters still containing liquid
sealant should be disposed of by your local
authorized Ford dealer or tire dealer, or in
accordance with local waste disposal
regulation.
Note:
After the sealing compound has been
used, the maximum vehicle speed is 50 mph
(80 km/h) and the maximum driving distance
is
120 mi (200 km). The sealed tire should
be inspected immediately.
You can check the tire pressure any time
within the
120 mi (200 km) by performing the
steps listed previously in the Second stage:
Checking Tire Pressure procedure.

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.

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.

T type tires have some additional
information beyond those of P type tires;
these differences are described below: A. T: Indicates a type of tire, designated
by the Tire and Rim Association, that is
intended for temporary service on cars,
sport utility vehicles, minivans and light
trucks.
B.
145: 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.
80: Indicates the aspect ratio which
gives the tire's ratio of height to width.
Numbers of 70 or lower indicate a short
sidewall.
D.
D: Indicates a diagonal type tire.
R:
Indicates a radial type tire.
E.
16: 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. 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
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 Permissible 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.
When weather temperature changes
occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop
can cause a corresponding drop of 1 psi
(7 kPa) in inflation pressure. Check your
tire pressures frequently and adjust
them to the proper pressure which can
be found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning they are not hot from
driving even a mile.

Note:
If you are checking tire pressure
when the tire is hot, (for example driven
more than 1 mile [1.6 kilometers]), never
bleed or reduce air pressure. The tires
are hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A hot tire
at or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to
get air for your tire(s), check and record
the tire pressure first and add the
appropriate air pressure when you get
to the pump. It is normal for tires to heat
up and the air pressure inside to go up
as you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire
gauge onto the valve and measure
the pressure.
3. Add enough air to reach the recommended air pressure. Note:
If you overfill the tire, release air
by pressing on the metal stem in the
center of the valve. Then recheck the
pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
Note: Some spare tires operate at a
higher inflation pressure than the other
tires. For T type mini-spare tires (refer
to the Dissimilar spare wheel and tire
assembly information for a description):
Store and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare tires
(refer to the Dissimilar spare wheel and
tire assembly information for a
description): Store and maintain at the
higher of the front and rear inflation
pressure as shown on the Tire Label.
6. Visually inspect the tires to make
sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak. 7. Check the sidewalls to make sure
there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve
Stems
Periodically inspect the tire treads for
uneven or excessive wear and remove
objects such as stones, nails or glass
that may be wedged in the tread
grooves. Check the tire and valve stems
for holes, cracks, or cuts that may permit
air leakage and repair or replace the tire
and replace the valve stem. Inspect the
tire sidewalls for cracking, cuts, bruises
and other signs of damage or excessive
wear. If internal damage to the tire is
suspected, have the tire demounted and
inspected in case it needs to be repaired
or replaced. For your safety, tires that
are damaged or show signs of excessive
wear should not be used because they
are more likely to blow out or fail.

WARNINGS
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.
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 feet (3.66
meters) 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. Safety Practices WARNINGS
If your vehicle is stuck in snow,
mud or sand, do not rapidly spin
the tires; spinning the tires can tear the
tire and cause an explosion. A tire can
explode in as little as three to five
seconds. Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander. Driving habits have a great deal to do
with your tire mileage and safety.
•
Observe posted speed limits.
• Avoid fast starts, stops and turns.
• Avoid potholes and objects on the
road.
• Do not run over curbs or hit the tire
against a curb when parking.

Highway Hazards
No matter how carefully you drive
there
’s always the possibility that you
may eventually have a flat tire on the
highway. Drive slowly to the closest safe
area out of traffic. This may further
damage the flat tire, but your safety is
more important.
If you feel a sudden vibration or ride
disturbance while driving, or you suspect
your tire or vehicle has been damaged,
immediately reduce your speed. Drive
with caution until you can safely pull off
the road. Stop and inspect the tires for
damage. If you cannot detect a cause,
have the vehicle towed to the nearest
repair facility or tire dealer to have the
vehicle inspected. Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole
can cause the front end of your vehicle
to become misaligned or cause damage
to your tires. If your vehicle seems to
pull to one side when you’re driving, the
wheels may be out of alignment. Have
an authorized dealer check the wheel
alignment periodically.
Wheel misalignment in the front or the
rear can cause uneven and rapid
treadwear of your tires and should be
corrected by an authorized dealer.
Front-wheel drive vehicles and those
with an optional independent rear
suspension may require alignment of all
four wheels.
You should balance the tires
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.Tire Rotation
Note:
If your tires show uneven wear
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation.
Note: Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. 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. If you have a
dissimilar spare wheel and tire assembly
it is intended for temporary use only and
should not be used in a tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval (as indicated in the Scheduled
Maintenance chapter) will help your tires
wear more evenly, providing better tire
performance and longer tire life.

The tire pressure monitoring system
complies with part 15 of the FCC rules and
with RSS-210 of Industry Canada. Operation
is subject to the following two conditions: (1)
This device may not cause harmful
interference, and (2) This device must accept
any interference received, including
interference that may cause undesired
operation.
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. 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 (If Equipped)
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.
