I do not necessarily agree, The tire manufacturer has a max load rating on the tire and that is at a specified pressure. If you look at the radials that wiould be a size for a C-2 Corvette, the max load rating is way above the weight of the car. The Automobile manufacturer will specify a tire pressure which is usually well below the Max Load Rating tire pressure that is on the tire itself.
I run the tires at the max load rating tire pressure when I am pulling my trailer and it is fully loaded. I run a much lower pressure when I run the truck escentially empty which is most of the time. When empty, at max load pressure, it will shake your teeth out.

The vehicle manufacturer specifies the recommended pressure, not the tire manufacturer; the max pressure molded into the sidewall is the maximum pressure recommended during tire mounting for bead seating. There's no vehicle manufacturer's recommended pressure for radials on a midyear, as radials were never used on them.
Many guys start at 32 psi with radials and adjust from there based on tread wear patterns and handling preferences.

I think that when you mix tire type, size and rim sizes that aren't original, you should go with the contact patch method for proper inflation. Go to a nice level smoth place and drive/roll over a piece of carbon paper to see the patch it leaves, even a piece of regular paper will work. The pattern should be uniform with no light or dark areas from side to side. This usually is a good guide to the right pressure and be fairly close. Too low- darker on the sides, too high- darker in the middle. You may get a range of pressures, then it's up to you if you want best handling and ride(low), best milage(high)
