M.Maximum Permissible Inflation
Pressure: Indicates the tire
manufacturers' maximum permissible
pressure or 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 vehicle
label.
The tire suppliers may have additional
markings, notes or warnings such as
standard load, radial tubeless, etc.

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 (T&RA), that
is intended for temporary service on cars,
SUVs, 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
250

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, (i.e. driven more than 1 mile
[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.
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.
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:
Tire Wear
252
Wheels and Tires
E142546
Page 253 of 423

When the tread is worn down to one
sixteenth of an inch (2 mm), 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 will appear on the tire
when the tread is worn down to one
sixteenth of an inch (2 mm)
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, etc.)
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
(TIN)
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.
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.
WARNINGS
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
253
Wheels and Tires
Page 254 of 423

WARNINGS
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. 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 ft (3.66 m)
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.
WARNINGS
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.
Safety Practices
WARNINGS
If your vehicle is stuck in snow, mud,
sand, etc., 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
254
Wheels and Tires
Page 255 of 423

•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 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 (if equipped) 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. 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.

Sometimes irregular tire wear can be
corrected by rotating the tires.
USING SNOW CHAINS
WARNING
Snow tires must be the same size,
load index, 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.
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.
Follow these guidelines when using snow
tires and traction devices •
If possible, avoid fully loading your
vehicle
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions.
• Use 10 mm cables or chains ONLY on
front axle with 235/55R17 tires.
• Not all S-class snow chains or cables
meet these restrictions. Chains of this
size restriction will include a tensioning
device.
• The snow chains or cables must be
mounted in pairs on the front axle.
• Do not use chains or cables on
235/50R18 and 235/45R19 tires.
• Install cables securely, verifying that
the cables do not touch any wiring,
brake lines or fuel lines.
• When driving with tire cables do not
exceed 30 mph (48 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Drive cautiously. If you hear the cables
rub or bang against the vehicle, stop
and retighten them. If this does not
work, remove the cables to prevent
vehicle damage.
• Remove the cables when they are no
longer needed. Do not use cables on
dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
