You can use one of my spreadsheets to calculate a pressure.
Can be found in next map on my onedrive that belongs to my hotmail.com adress with same username as in this forum ( so jadatis).

You can also fill in in the claud excell programm , but then if you look back later, you see your chanches you made or from others behind you.
So best is to download it to your computer, and after eventuall virus-check, open it in Excell or similar programm on your computer.
You can also download it to your own ondrive and use the excell like programm in the claud.
Determing the real weights, best on seperate axle-ends, , is as already written, the most tricky part in it all.
If you only fill in in part 1 of my spreadsheet, the GAWR's and GVWR, then the spreadsheet calculates for those, front adding 5% because front seldom overloaded, but if you have other idea , you can chanche the % in dark blue cell.
Rear calculates then for lighter vehicles adding 18% and a floating scale to 10% for the heavyer motorhomes.
If real weights filled in , uses 10% adding on given weight for R/L unbalans.
And if you still think this is to complicated , let me do it, give the needed data.
If you have a tag-axle so 3 axles total of wich 2 behind different gawr, you have to make 2 calculations, the spreadsheet is made for only 2 axles ( or tamdem).
