I also think the pressure needs to be adjusted for ride and total carried
weight.

I could be wrong but I think it is a misconception about minimum load
rating.  You want a tire that supports the Gross Axle Weights.  When VW
selected a tire that could be inflated well above the GAWR, they chose lower
inflation pressures that brought load capacity down to the GAWR for a
smoother ride.  That is how they came up with 30/40 psi on the 97R Michelin
MXT.  And same thing for the 185R commercial tires.  They did not inflate
them to the max, but where they set them, was at or close to the gross axle
weight.

So if your tires are capable of carrying the max axle weeights and you set
the pressure of your new tires to a point where it supports the gross axle
weight, you are at the correct load.
