Simple answer, always inflate to the max pressure found on the sidewall of the tire, but only when tires are cool. Underinflated tire sidewalls flex and build up heat, and that's what causes blowouts. So that's the actual answer to the actual question, everyone can talk about weight ratings and loads etc all day long.
Thank you for getting the thread back on track...see what I did there? I inflated to 100 psi and made the 1200 mile trip to Acadia. Maybe I pushed my luck a bit being 10 under sidewall/sticker psi, but I did go 3000 miles last year at 90 without incident. I know....past results don't mean future success.
