SECTION THREE
To determine individual wheel position weights, it is
necessary to repeat the first three steps, but this time, use
only one side of the scale as shown .
To calculate the opposite side of the vehicle wheel
position weight, subtract this side’s weights from the
weights recorded in steps 1, 2 and 3 . If there is a towed
vehicle, proceed to step 4 to obtain the “towed vehicle
only” weight .
The motorhome must remain as level as possible on
the scale (even though an axle or side is not physically
on the scale) to obtain accurate side-to-side scale
readings . There must be enough space on either side of
the scale to accommodate the width of the motorhome
being partially off the scale . It may be necessary to use
wheel ramps to get the required side to-side leveling .
If there is a difference in the weights on one side of
the vehicle as compared to weights on the other side,
components (tires, wheels, brakes, springs, etc .) on
the heavier side could be overloaded, even though the
total axle load is within the GAWR . It is important to
redistribute the load to avoid component failure, as
well as to improve the handling characteristics of the
vehicle .
With these actual weights, it is now possible to
compare them against the GAWR, GVWR, and tire
capacities . These actual weights are also what will
be used to determine proper tire inflations pressure .
Options to help assist when weighing the motorhome
include using “truck stop” scales . There is usually a
small fee for this service .
Refer to the load inflation table published by the tire
manufacturer to determine proper inflation pressure
recommended for single and dual wheel positions . The
heaviest wheel position (if applicable) on a single axle
will determine the inflation pressure for all tires on that
axle due to weight transfer that occurs when cornering .
DANGERS OF OVERLOADING
Do not overload the motorhome . In addition to possible
problems with tires, wheels, and air springs (air bags),
WARNING:
For safety, Do Not store or carry propane
containers, gasoline, or other flammable liquids
inside the motorhome .
WARNING:
Improperly inflated or overloaded tires can
cause a blowout . An overloaded axle can cause a
component failure of the suspension system . Tire
blowout or broken suspension components can
lead to loss of vehicle control resulting in property
damage, personal injury or death .
CAUTION:
Even though the weight of the total axle may be
within the axle’s rating, it may be overloaded on
one side . This causes one wheel position to be
overloaded; therefore, side-to-side weighing is
required .

CAUTION:
Refer to the tire load inflation table published by the
tire manufacturer to determine the proper inflation
pressures recommended for single and dual wheel
positions . Always inflate each axle set to the tire
with the higher of the side-to-side weight .
CAUTION:
If actual weight carried by any tire is below the load
inflation table minimum pressure, inflate the tire(s)
to the minimum inflation in the load inflation table .
Setting tire pressure below the minimum inflation
pressure can overheat and damage the tire casing
leading to premature tire failure or blowout .
