coach weighing procedure

[thomas_sorrentino]

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.
