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.

200

Wheels and Tires

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 or

Tire 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.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles

Note:

Do not reduce tire pressure

to change the ride characteristics
of the vehicle. If you do not
maintain the inflation pressure at
the levels specified by Ford, your
vehicle may experience a condition
known as shimmy. Shimmy is a
severe vibration and oscillation in
the steering wheel after the vehicle
travels over a bump or dip in the
road that does not dampen out by
itself. Shimmy may result from
significant under-inflation of the
tires, improper tires (load range,
size, or type), or vehicle
modifications such as lift-kits. In
the event that your vehicle
experiences shimmy, you should
slowly reduce speed by either lifting
off the accelerator pedal or lightly
applying the brakes. The shimmy
ceases as the vehicle speed
decreases.

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

201

Wheels and Tires

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 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 1.0 mi
(1.6 km)), 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.

202

Wheels and Tires

Note:

Some spare tires operate at

a higher inflation pressure than the
other tires. For T type mini-spare
tires, (see 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, see 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
Safety Compliance Certification
Label or 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.

Tire Inflation Information

WARNING:

An inflated tire

and rim can be very dangerous
if improperly used, serviced or
maintained. To reduce the risk
of serious injury, never attempt
to re-inflate a tire which has

been run flat or seriously
under-inflated without first
removing the tire from the wheel
assembly for inspection. Do not
attempt to add air to tires or
replace tires or wheels without
first taking precautions to
protect persons and property.

All tires with Steel Carcass Plies
(if equipped):

This type of tire utilizes steel cords

in the sidewalls. As such, they
cannot be treated like normal light
truck tires. Tire service, including
adjusting tire pressure, must be
performed by personnel trained,
supervised and equipped
according to Federal Occupational
Safety and Health Administration
regulations. For example, during
any procedure involving tire
inflation, the technician or
individual must utilize a remote
inflation device, and ensure that
all persons are clear of the
trajectory area.

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.

Improper or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all your
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:

205

Wheels and Tires

Tire Wear

E142546

When the tread is worn down to
one sixteenth of an inch (2
millimeters), tires must be
replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which
look like narrow strips of smooth
rubber across the tread appears
on the tire when the tread is worn
down to one sixteenth of an inch
(2 millimeters).

When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.

Damage

Periodically inspect the tire treads
and sidewalls for damage (such
as bulges in the tread or sidewalls,
cracks in the tread groove and
separation in the tread or
sidewall). If damage is observed

or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.

Age

WARNING:

Tires degrade

over time depending on many
factors such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives.
In general, tires should be
replaced after six years
regardless of tread wear.
However, heat caused by hot
climates or frequent high loading
conditions can accelerate the
aging process and may require
tires to be replaced more
frequently.
You should replace your spare
tire when you replace the road
tires or after six years due to
aging even if it has not been
used.

U.S. DOT Tire Identification
Number

Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and

206

Wheels and Tires

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.

This begins with the letters DOT
and indicates that the tire meets
all federal standards. The next
two numbers or letters are the
plant code designating where it
was manufactured, the next two
are the tire size code and the last
four numbers represent the week
and year the tire was built. For
example, the numbers 317 mean
the 31st week of 1997. After 2000
the numbers go to four digits. For
example, 2501 means the 25th
week of 2001. The numbers in
between are identification codes
used for traceability. This
information is used to contact
customers if a tire defect requires
a recall.

Tire Replacement
Requirements

Your vehicle is equipped with tires
designed to provide a safe ride
and handling capability.

WARNING:

Only use

replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The

recommended tire and wheel
size may be found on either 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 the
Tire Label which is located on
the B-Pillar or edge of the
driver's door. If this information
is not found on these 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.

WARNING:

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.

207

Wheels and Tires

WARNING:

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.

WARNING:

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.

WARNING:

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
(3.6 m) away from the wheel
and tire assembly.

•

Use both eye and ear
protection.

Important:

Remember to replace

the wheel valve stems when the
road tires are replaced on your
vehicle

The two front tires or two rear tires
should generally be replaced as a
pair.

The tire pressure sensors mounted
in the wheels 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 tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.

Replacing a Tire That is
Greenhouse Gas Certified

The tires installed on this vehicle
at the factory as original
equipment are certified for
Greenhouse Gas and Fuel
Efficiency regulations.
Replacement tires must be of
equal or lower rolling resistance
level (TRRL or Crr). Consult with
your tire supplier(s) for
appropriate replacement tires.

Safety Practices

WARNING:

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.

WARNING:

Do not spin the

wheels at over 34 mph
(55 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 when 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 a tire is
under-inflated or damaged,
deflate it, remove wheel and
replace it with your spare tire and
wheel. 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
independent rear suspension may
require alignment of all four
wheels.

The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.

209

Wheels and Tires

Tire Rotation

WARNING:

If the tire label

shows different tire pressures for
the front and rear tires and the
vehicle has a tire pressure
monitoring system, then you
need to update the settings for
the system sensors. Always
perform the system reset
procedure after tire rotation. If
you do not reset the system, it
may not provide a low tire
pressure warning when
necessary.

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) helps your
tires wear more evenly, providing
better tire performance and longer
tire life. Sometime irregular tire
wear can be corrected by rotating
the tires.

If your vehicle is equipped with
dual rear wheels it is
recommended that the front and
rear tires (in pairs) be rotated only
side to side. We do not
recommend splitting up the dual
rear wheels. Rotate them side to
side as a set. After tire rotation,
inflation pressures must be
adjusted for the tires new
positions in accordance with
vehicle requirements.

USING SNOW CHAINS

WARNING:

Snow tires must be the

same size, load index, and speed rating
as those originally provided by Ford. 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. It is also strongly advised to
follow the Ford recommended tire
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 which is
located on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.

The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.

Note:

The suspension insulation and

bumpers help prevent vehicle damage. Do
not remove these components from your
vehicle when using snow tires and chains.

Follow these guidelines when using snow
tires and chains:

211

Wheels and Tires

•

If possible, avoid fully loading your
vehicle.

•

Use only SAE Class S chains.

•

Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.

•

Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.

•

Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.

If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.

TIRE PRESSURE MONITORING
SYSTEM

(IF EQUIPPED)

WARNING:

The tire pressure

monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.

WARNING:

Changes or

modifications not expressively approved
by the party responsible for compliance
could void the user's authority to operate
the equipment. The term "IC:" before the
radio certification number only signifies
that Industry Canada technical
specifications were met.

Note:

You should only use tire sealants in

roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.

Note:

If the tire pressure monitoring system

sensor becomes damaged, it may not
function.

Each tire, including the spare, if
provided, should be checked
monthly when cold and inflated

to the inflation pressure recommended by
the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. If
your vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.

As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle’s handling and stopping ability.

Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver's responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.

212

Wheels and Tires

Your vehicle has a TPMS malfunction
indicator to indicate when the system is
not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale flashes
for approximately one minute and then
remains continuously illuminated. This
sequence continues upon subsequent
vehicle start-ups as long as the
malfunction exists.

When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

This device complies with Part 15 of the
FCC Rules and with License exempt RSS
Standards of Industry Canada. Operation
is subject to the following two conditions:

1.

This device may not cause harmful
interference.

2. This device must accept any

interference received, including
interference that may cause undesired
operation.

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 turns 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.

213

Wheels and Tires

When Your Temporary Spare Tire is
Installed

When you replace one of the road tires
with the temporary spare, the system
continues to identify an issue to remind
you that you need to repair and put back
on the damaged road wheel and tire
assembly 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:
