The inflation tables are designed (hopefully) to provide the optimal conditions for a given weight. More pressure up to the max can cause more tire rounding and less traction and center wear for example. Inflation for all tires on a axle is the same and based on the heavest side.
Tires aren't always what they should be and I remain negative on Michelin and Goodyear due to my experience with cracking and other issues.
Having apologized for not figuring out the information offered on the website I was going to shut up but you made three good points which I agree with. . As you mentioned too many psi for the load does make the tire wear in the center and also reduces traction. That is why I always (as you also suggested) find and use the manufacturers load and inflation for that tire.
I also share your mistrust of Michelin and Goodyear. I had a set of Michelin RV tires begin to crack in the sidewalls as they hit five years and had to replace them. I also had a set of Goodyear RV tires that began blowing out at around five years. I an anal about tire pressure and I also check temps with an IF thermometer at every stop. Thus the Sumitomo's.
Thanks all for the help.
