I assume that the upshot of all this is that the lower PSIs (as adjusted for weight) give more comfort without sacrificing performance or durability. Do I have this right? I'm a little confused about the comments that lower PSI helps protect against flats (crossing fingers: I've never had one going back to 74 when I got my Stella 10 speed; which is still a pretty functional bike, by the way). At least on car tires, they say higher PSI gives better durability. Is this apples & oranges? Thanks for the info.

Sorry...let me step back from my recomendation. The pressure seemed low in my eyes as well, but for your light weight on such a large tire they don't seem totally out of line. I believe your rim on that pilot would handle a 23, but 25's would probably be a better recomendation(83F-92R).
The "correct" pressure in your tire is what will allow it to perform the best for both comfort and durability.
BTW the "Max" pressure listed on the sidewalls has more to do with legalities than with performance.
