Just an FYI, I commute half the time on 32.5mm actual width (700x32C) Michelin Dynamics (the old ones before they replaced them with Dynamic "Sport"). The max side wall pressure says something like 57 psi. The Michelin Dynamic 700x28C says 87 psi on the side wall. I pump of the tires to roughly 65 psi and 95 psi respectively. Haven't ever had a pinch flat and probably because I do bunny hop and ride lightly on the saddle. But I also have a rack on the back and haul gear that stays over the rear wheel and doesn't hop lightly over bumps. That said, when it comes to wheels, I'm a strong believer in riding lightly, and also a strong believer building them myself. And that seems to allow me to ride relatively carefree and I'm well over 220 lbs.
