Scale:
Certified public scales are located in a variety of places such as moving and
storage lots, farm suppliers with grain elevators, gravel pits, recycling
companies and large commercial truck stops.
If you are not aware of a nearby public scale, check the local area telephone
book yellow pages under "scales-public" section or "weighers." A nominal fee
will be charged, but this is money wisely spent.
Weight scale types and weighing methods will affect the procedure used to
determine proper tire inflation pressure and axle loading.
There are several types of scales in use today. A Platform Scale will allow
the entire motorhome to fit on the scale, which will read the GVW with only
one scale recording required. A segmented Platform Scale is designed to weigh
only one axle at a time, which may require two or three scale readings to
determine the GAW or GVW total.
A Single Axle Scale enables one axle at a time. Some scales will read only
one wheel position at a time due their physical size. Several scale readings
may be required to determine the GAW or GVW total.
Slide-out equipped motorhomes will require each wheel position to be
weighed. This is referred to as a four corner weigh. This type of weighing
procedure will accurately determine what the correct tire inflation pressure
should be. Depending on the type of scale being used, several different scale
readings may be required.
NOTE: The most accurate method to determine proper tire pressure
is a four corner weigh. A slide out motorhome will require each tire
to be weighed independently. Weighing an axle will net the total
weight carried by that axle. When calculating the drive axle dual
tire pressure using a independent corner weigh method, divide the
total weight by two to determine the weight carried by each tire.
When weighing the entire drive axle, divide the total weight by four
to determine the approximate weight carried by each tire.
