I ran 700x23 Michelin Pro 2/3/4 Race Service Course at 120psi for years, never had any rim failures directly attributable to that. I had a sidewall failure once but i booted the hole with a $20 bill and made it home alright. These were for a go-fast bike I don't have anymore, that had tight clearance with 23mm tires! I was thinner then, more in the 230-250 range.
Back on topic...I run 700x38 Barlow Pass standard sidewalls (I know, a little bigger than you asked) on my Redwood at 50psi front, 55psi rear. Rider weight 300+. I don't know exactly how much the + is because I don't weigh myself that much. I'm sure my performance on the 74 mile ride I'm doing on Saturday will let me know.
