My roadies have 23's, 25's or 28's (90 to 120psi). My commuter Trek has 32's (75psi). The 650b equipped bike has Gravelkings that measure out to a true 41 (45psi).
If I'm riding pavement, I'll take the 23/25's. Crushed limestone trails get the 28 or 32's. The 650b is almost entirely gravel bound. I weigh in at 220 these days.
