Look at my webpage on the subject:
Barry's Tire Tech: Load Tables
Notice that the load table indicates that the max load occurs at 35 psi. We tire engineers called that the rated load - and the corresponding pressure is called the rated pressure.
While I only published one page from an older TRA yearbook, the other pages are similar, regardless of year. In other words, these things don't change over time. If you go to other tire yearbooks - like ETRTO or JATMA, you will see something similar.
And, yes, if you change tire size on your car, that might change what pressure might be appropriate. However, it doesn't change the tire's rated pressure.
