Vehicle/Trailer Loads
*
[DR28801( ALL)06/92]
All vehicles may tow a Class I trailer provided
the Gross Combined Weight (GCW) is less than
or equal to the GVWR shown on the Safety
Compliance Certification Label. For heavier
trailer applications, refer to the towing
information found later in this chapter.
*
[DR28850( M)04/95]
Trailer Towing
*
[DR29001( ALL)03/91]
Towing a trailer puts additional loads on your
vehicle's engine, transmission, axle, brakes, tires
and suspension. For your safety and for the
good of your vehicle, use the right equipment
for the type of trailer you tow.
*
[DR29025( ALL)09/92]
Your trailer towing capability will vary based on
the standard and optional equipment on your
vehicle. Refer to the followingVehicle
Loading/Towing Informationand the Trailer
Towing Tables to determine the specific towing
capability of your vehicle.
*
[DR29050( ALL)02/92]
q
Stay within the load limits when you tow.
*
[DR29101( ALL)01/95]

[DR30950( ALL)06/92]
The rating is based on the carrying capacity of
thelowest ratedaxle and suspension component
as well as other factors. This is why it's so
important to observe vehicle loading ratings.
Overloading a vehicle punishes components and
can lead to shortened service life or outright
failure.
*
[DR31001( ALL)06/92]
The capacity of the tires is included as part of
the axle and suspension system, which is to be
considered when determining the lowest rated
component. Tires are rated to carry a specific
maximum load at a specific maximum tire
pressure.
*
[DR31050( ALL)06/92]
Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[DR31110( ALL)06/92]
With the tires inflated to the specified pressure
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[DR31120( ALL)06/92]
GCWR (Gross Combined Weight Rating)
*
[DR31130( ALL)06/92]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.

Preparing to Change the Tire
*
[RE15250( ALL)12/91]
NOTE: To lift your vehicle by other than the
front or rear jacking points, be sure to
use only hoist adapters with a wide
contact surface.
*
[RE15325( E M)03/95]
1. Make sure that your vehicle will not move
or roll. Put the gearshift in P (Park). Set the
parking brake and block the wheel that is
diagonally opposite the tire that you are
changing.
[RE15445( FM)05/95]
On F-Super Duty vehicles, the parking brake is
on the transmission. Therefore, the vehicle will
not be prevented from moving when a rear
wheel is lifted, even if the vehicle is in Park and
the parking brake is applied. Be sure to block
both directions of the wheel that is diagonally
opposite to the wheel that is being lifted.
*
[RE15450( FM)05/95]
RWARNING
If the vehicle slips off the jack, you or
someone else could be seriously injured.
[RE15490( M)05/95]
RWARNING
Do not put any part of your body under
the vehicle. Do not start the engine when
your vehicle is on the jack. Never raise
your vehicle by using a bumper jack.
[RE15495( M)05/95]
The jack is only for changing the tire in
emergencies. The Ford F-Super Duty Jack is
recommended. Use safety stands if you want to
service the vehicle.
[RE15510( M)05/95]
If an alternative jack is used, it must have a
curved surface swivel head compatible with the
stripped chassis jacking surfaces and must have
a minimum load rating of 4 tons. Do not use a
button head type jack.

Replacing the Tires
*
[SV27400( ALL)05/95]
Replace any tires that show wear bands. When
your tire shows a wear band, it has only 1/16
inch (2 mm) of tread left.
*
[SV27500( ALL)10/89]
quarter page art:0060006-A
Wear band
*
[SV27600( ALL)01/95]
Because your vehicle's tires may wear unevenly,
you may need to replace them before a wear
band appears across the entire tread. Some spots
wear more heavily than others.
*
[SV27700( ALL)03/90]
Your wheels and tires are match-mounted for
improved ride. Before you begin to repair a tire,
mark the wheel and tire so that they are
properly aligned when remounted. This will
ensure that the tires will continue to give you
the same ride level.
*
[SV27851( ALL)01/95]
RWARNING
When replacing full size tires, never mix
radial, bias-belted, or bias-type tires. Use
only the tire sizes that are listed on the
tire pressure decal. Make sure that all tires
are the same size, speed rating, and
load-carrying capacity. Use only the tire
combinations recommended on the decal.
If you do not follow these precautions,
your vehicle may not drive properly and
safely.

[SV27860( ALL)03/90]
RWARNING
Make sure that all replacement tires are of
the same size, type, load-carrying capacity,
and tread design (e.g. ªAll Terrainº, etc.),
as originally offered by Ford.
*
[SV27885( ALL)04/95]
RWARNING
Do not replace your tires with ªhigh
performanceº tires or larger size tires.
*
[SV27895( ALL)05/95]
RWARNING
Failure to follow these precautions may
adversely affect the handling of the
vehicle and make it easier to lose control
and roll over.
*
[SV27900( ALL)01/95]
Tires that are larger or smaller than your
vehicle's original tires may also affect the
accuracy of your speedometer.

RWARNING
Aftermarket wheel assemblies may not be
compatible with your vehicle and should
not be used. Use of incompatible wheel
assemblies may result in equipment
failure and possible injury.
[SV28730( M)05/95]
A wheel or tire of the wrong size or type may
adversely affect such things as load carrying
capacity, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping
ability, headlight aim, bumper height, vehicle
ground clearance, and tire or tire chain clearance
to the body and chassis. Replacement with used
wheels is not advised: they may have been
treated harshly or have high mileage, and they
could fail without warning.
[SV28732( M)05/95]
The use of wheels with load carrying limits
higher than the limits of the wheels originally
installed on your vehicle does not in itself
increase the GAWR or GVWR of the vehicle.
[SV28735( M)05/95]
RWARNING
Only wheel assemblies approved and
released by Ford Motor Company for your
vehicle model should be used.
[SV28745( M)05/95]
RWARNING
Alterations to the vehicle suspension or
steering by raising the chassis (i.e., use of
aftermarket ªlift kitsº) may adversely
affect vehicle handling and braking
performance.
