Give GY Tech a call and ask them what to do when going from a "E" to "G" tire. They will tell you to use the chart and add 5psi.
Why do you think they make the chart? MOST RV's axle rating is determined buy the tires capacity at MAX psi.
Using that method on the LT235/85R16E to a LRG would increase the load capacity from 3042# to 3170#.
The same method for a ST235/85R16E to LRG would increase the load capacity from 3640# to 3750#.
As you can see, load inflation charts are not compatible between tire size designations.
Not sure your point as it relates to what I said.
Just pointing out that each designated tire size has its own standardized load inflation chart.
LT235/85R16 is a designated tire size. ST235/85R16 is a designated tire size. A tire's load rating, weather it be from its load index number or load range leter is a condition of the tire and not rerlated to its size.
