    							*Temperature: 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.
    M. Maximum 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 vehicle 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 vehicle label.
    The tire suppliers may have
    additional markings, notes or
    warnings such as standard load
    or radial tubeless.
    Additional Information
    Contained on the Tire Sidewall
    for LT Type Tires

    Information on T Type Tires
    T145/80D16 is an example of a
    tire size.
    Note: The temporary tire size for
    your vehicle may be different from
    this example. Tire Quality Grades
    do not apply to this type of tire. 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.

     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 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.
    380
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and Tires 
    						
    							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
    will cease 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
    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 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.
    381
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and Tires 
    						
    							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, (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
    382
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and Tires 
    						
    							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.
    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. 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
    383
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and TiresE161437  
    						
    							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
    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 will
    appear 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
    WARNINGS
    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 or even
    if they have not been used.
    However, heat caused by hot
    climates or frequent high-load
    conditions can accelerate the
    aging process and may require you
    to replace tires more frequently.
    384
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and TiresE142546  
    						
    							WARNINGS
    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
    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 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.
    385
    Super Duty (TFE) Canada/United States of America, enUSA, First Printing Wheels and Tires 
    						
    							WARNINGS
    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.
    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.
    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
    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 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 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.
