Planning and Preparation
Weight Distribution
To obtain the individual wheel position weights, repeat this process with only one side
of the motorhome on the scale. To determine individual wheel position weights, it is
necessary to repeat the previous three steps (1a, 1b, and 1c), but this time, use only
one side of the scale. To calculate the opposite side of the vehicle wheel position
weight, subtract this side’s weights from the weights recorded in steps 1a, 1b, and 1c.
Your motorhome must remain as level as possible on the scale, even though
an axle or side is not physically on the scale.
To obtain the side-to-side weights,
there must be enough space on either side of the scale to allow the motorhome to be
partially off the scale.
Individual wheel position weights must not exceed the maximum tire load capacity.
Maximum tire load capacity can only be achieved by
utilizing the maximum allowable pressure (psi) as listed
on the sidewall of the tire.

For improved accuracy, Thor Motor Coach recommends using a segmented 4-pad
scale, when possible, to determine individual wheel weights. The corner weights
should not exceed half of the respective Gross Axle Weight Rating (GAWR) or the
maximum load rating for the tire or set of dual tires at the rear, whichever is less.
The maximum load rating for the tire can be found embossed on the tire’s sidewall.
If any of the corner weights exceed half of the listed GAWR or tire ratings, relocate
the passengers and redistribute or remove a portion of the cargo until the weight is
within the proper limits for all four corners of the vehicle.
Note:
Additional cargo carrying capacity can be obtained by reducing the
amount of fresh water carried while driving.
Check vehicle weight periodically to obtain optimum mileage from tires and
improve handling. Tires should always be inflated as recommended in the chassis
manufacturer’s instructions or on the tire sidewall. See your chassis operator’s
manual.
Improper weight distribution or too much weight on your motorhome’s suspension
system can cause spring, shock absorber, or brake failure, handling or steering
problems, irregular tire wear, tire failure or other damage.
An overloaded motorhome is hard to drive and hard to stop. In cases of serious
overloading, brakes can fail completely, particularly on steep hills. The load a tire will
carry safely is a combination of the size of tire, its load range, and corresponding
inflation pressure.
Note:
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 should be
done.
