I'm around ~200lb in riding gear and ride 30-32 PSI in the front and 32-35 PSI in the rear. Any lower and I'm gonna get a pinch flat; I'm a fairly smooth rider, but I don't go slow and will hit 99% of features on most trail networks (routinely hit everything at LDT and most everything at Lynn/Vietnam).

Stan's flow rims with a 2.5 DHF and a 2.35 DHR.
