Weight and Tire pressure help

[triton]

On our last trip we weighed the coach at a Cat scale in FL on our way
home and this is what we got:
Steer Axle: 9980lb
Drive Axle: 17700lb
trailer axle: 4620

Gross weight: 32300

The tires are Michelin XZA2 22.5

The coach is a 2001 Travel Supreme with toad Acura MDX pulled 4-down

Front GAWR: 12000
Rear: 17000

So how over weight are we it looks like 700 in the rear??
We have 1/2 tank of propane, no water, grey tank 1/2full, black tank
1/2 full, Full gas tanks
and all the accumulated junk that comes with 4 kids coming back from 2
weeks at disney
Tire pressures we are running are: around 100
This is where I'm confused the coach says one pressure the tires say
another pressure
What tire pressures should we be running?
Any suggestions
Thanks

Janelle,

If you go to www.michelinrvtires.com, and click on RV Tire Guide, then
download the tire guide you will find a wealth of info. On page 20 you
will find a chart for Inlation Charts for RV Usage, which will give
you the recommended inflation for various weights.

We have basically the same coach, tho a 2002 on a Spartan Mountain
Master GT chassis. It's axle ratings are 12,600 front and 20,000 rear.
If your figures are what are on the 2001 chassis, then yes, you are 700
pounds overweight. You should try to move as much heavy weight in your
basement bays as far forward as possible to transfer more weight to the
front. You should also be aware that the total axle weight can be
misleading since there can be as much as 1,000 difference between left
and right side corner weights. Motor homes should be weighed 4 corners.
It's not always feasible and the CAT scales will do temporarily, so you
should try to get the coach corner weighed. This can usually be done at
FMCA National conventions or very large rallies. In the meantime, I'd
keep the rear tires aired up to the maximum pressure shown on your
chassis chart next to the driver's seat. On the XZA2s and your weight
you can drop the fronts to 90 psi.
