Scales
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 tele-
phone 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. The size of some
scales will allow the entire motorhome to fit on the scale, which will read the
GVW with only one scale recording required. Other scales are designed to
weigh only one axle at a time, which may require two or three scale readings
to determine the GAW or GVW total. 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. Slide out motorhomes
with a Tag Axle will require a six position weigh. This type of weighing pro-
cedure 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 calcu-
lating the drive axle dual tire pressure using a independent cor-
ner 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 approxi-
mate weight carried by each tire.
