All the information you need to understand your tires is found on the tire itself.  Once you understand this then you can more on to the next step.

The actual weight of your RV is an important number.  It is important that you weigh the RV in its fully loaded condition ie as you plan to travel - full tank of gas, oil, passengers, food, equipment and supplies.   The best practice is to weigh each  wheel.

Once you have the actual weight of your RV you can then pick the proper inflation of your tires.   This is a number based on cold tires ie driven on less then 15 minutes.  As the air heats up in hour tires the air pressure will increase.   The tire companies have no idea what the temperature is inside your tires at any given point.  They assume a cold tire is the best reference point.   There is  an assumption the you will stay at the same attitude as you start when the measurement is taken.  One of the reasons you check you air pressure daily is to compensate for the  'maybe' changes in attitude.   As you get up in attitude you tire pressure will increase.  But that is small compared to the change caused by heat.

A great help.  Can someone point me to a chart for non XPS RIB tires. The LD came with the LTX tire that were just replaced with LTX M&S 2.  Stock size, 225 75 R 16 load range E.
 I just had the RV weighed in FL at a state weight station (f=4180, r=8180 Gross 12360 good thing the numbers added up).
I am traveling and have very limited wifi and cell connection.

I have been running 70 front and 75 rear but think that may be on the hard side.  I don't mind the ride but don't want to shake the RV to bits either.  I got the numbers from page 94 of the owners manual.  I figured for an almost full LD to be safe.  The LD chart is a few years old while the Michelin site is constantly updated. Not seeing better info I will use the LD chart but for the next higher weight.

Also not sure I am reading the paper correctly.  I am assuming (I know the translation for assume) Weight 1 is the front axel, Weight 2 the Rear Axel.  They also had Front Bridge 12360, Rear Bridge 8180 Gross Weight 12360.
