coach weighing procedure

[Neil & Pat]

Hi Tom, Neil here, ex A’Weigh We Go, and PT-36 owner; sorry to inform you
but the weights that you inherited are just not adequate. You will require,
at minimum, the three individual axle weights to take an informed stab at
setting tire pressure reasonably close, and by the way reasonably close in
not really adequate. The right answer is to find yourself a friendly truck
weighing service, highway truck stop, agriculture scales, gravel pits or
many others; if none of these are obvious, stop a trucker and ask where you
can have your rig weighed. Have the three axles weighed individually with
your rig setup as you travel; I suggest, full fuel, full fresh water and
full propane but no grey or black water. If the scale operator can
accommodate also have the same three weights with only one side on the scale
(right or left) this will allow you to determine wheel-by-wheel weights
which is exactly what you are seeking.

With these weights available you are now able to determine the heaviest tire
on each axle; use that value to determine the pressure required from the
specific tire manufacturers charts for all tires on that axle. In all cases
round pressure values upward to the next full 5 psi value and in the case of
the front tires you may wish to add 5 psi. Nothing less will do!

In the case of your PT38 you should find your pressures to approximate
115-120psi front, 100-105psi mains and 80-85 psi on the tags. Do yourself a
favor now and do it correct and you will only have to do it once.

I'm trying to determine the correct tire pressures for my weight and
tires, in preparation for getting the correct set of cross-fires. I
have the weights written down from the previous owner. 13,700 for the
front and 28980 for the rear. That weight for the rear puts me right
off the tire chart! Does anyone know the correct procedure for weighing
the rear axle? ie: tag axle dumped or down/ tags on the scale or off?
Sorry if this is a dumb question.
