WRONG!!! or to be more precise half true.
The tires say Maixmum load of xxxx at maximu pressure of yyy
They do not show the proper pressure for the load they carry,
Neither does any sticker, placard or label inside or outside the RV.
The only way to be sure is to put it on a scale and weigh it, each wheel
That said, on a trailer it is not quite as important as on a motor home or other tow vehicle.
I would park the unit on a scale, divide the weight by the number of tires and go to the tire maker's web page and figure it out from there.
Note, doing this may wind up with one tire a bit over and one a bit under inflated (side to side differences) so add five PSI.
Alternative: Weigh both sides.
