which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
SERVICING YOUR TIRES
Checking the tire pressure
•Use an accurate tire pressure gauge.
•Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km
(3 miles).
•Adjust tire pressure to recommended specifications found on the
Certification Label. Tire pressure information can also be found on the
Tire Information label located on the inside of the fuel filler door.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control, vehicle
rollover and/or personal injury.

Tire inflation information
The F450 and F550 vehicles are equipped with a tire that is an all-steel
radial. All-steel radial tires utilize steel cords in the sidewalls, and also
require increased inflation pressures of up to 95 psi. 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 insure that all persons are clear of
the trajectory area.
WARNINGAn 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 rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
The following procedure applies to vehicles equipped with single rear
wheel.

•DRW–Six tire rotation
If your vehicle is equipped with dual
rear wheels it is recommended that
front and rear tires (in pairs) be
rotated only side to side, with the
rear tires maintaining original
vehicle position. After tire rotation,
inflation pressures must be adjusted
for the tires new positions in
accordance with vehicle
requirements.
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads. Due to exposure to the
elements and exhaust you should
replace the spare tire when you
replace the other tires.
When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification Label. Make sure that all tires are the same size, speed
rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle handling may be affected which can lead to loss of vehicle
control, vehicle rollover and/or personal injury.

Make sure that all replacement tires are of the same size, type,
speed rating, load-carrying capacity and tread design (e.g.,“All
Terrain”,“Touring”, etc.), as originally offered by Ford.
Do not replace your tires with“high performance”tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle, and increase the risk of loss of vehicle
control, vehicle rollover and/or personal injury.
Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
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 chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•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 re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
