Ford Excursion (2005 year). Manual — part 34

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 tire label or certification 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 manufactures’
maximum permissible pressure and/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 either the tire label or certification 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 tire label or certification 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 tire label or certification label.

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.

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 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. Never “bleed” or reduce air
pressure when tires are hot.

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 pushing 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 require higher inflation pressure than the other
tires. Check the tire label on the B pillar or the edge of the driver’s door
for the recommended spare tire pressure.

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

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 (OSHA) 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.

WARNING An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid 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.

TIRE REPLACEMENT REQUIREMENTS

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

Only use replacement tires and wheels that are the same size
and type (such as P-metric versus LT-metric or all-season versus

all-terrain) 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 or transfer case/power transfer unit failure. If
you have questions regarding tire replacement, see an authorized Ford
or Lincoln-Mercury dealer.

Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand, load-carrying capacity and speed rating because it
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.

You should replace the spare tire when you replace the other road tires
due to the aging of the spare tire.

CHANGING THE TIRES

If you get a flat tire while driving:
• do not brake heavily.
• gradually decrease the vehicle’s speed.
• hold the steering wheel firmly.
• slowly move to a safe place on the side of the road.

The use of tire sealants is not recommended and may damage
your tires.

Dissimilar spare tire/wheel information (if equipped)

Failure to follow these guidelines could result in an increased
risk of loss of vehicle control, injury or death.

Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel, 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 tire/wheel 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.

When driving with the dissimilar spare tire/wheel, do not:
• Exceed 70 mph (113 km/h)
• Use more than one dissimilar spare tire/wheel at a time
• Use commercial car washing equipment
• Use snow chains on the end of the vehicle with the dissimilar spare

tire/wheel

The usage of a dissimilar spare tire/wheel 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
• Wet weather driving capability
• All-Wheel driving capability (if applicable)
• Load leveling adjustment (if applicable)
When driving with the dissimilar spare tire/wheel additional caution
should be given to:
• Towing a trailer
• Driving vehicles equipped with a camper body
• Driving vehicles with a load on the cargo rack
Drive cautiously when using a dissimilar spare tire/wheel and seek
service as soon as possible.
