However, most people on here go way above 100 psi to avoid pinched tires.
I like 95-100 psi rear, 90-95 psi front and switched from 23 to 25mm tires after growing to 200 pounds.
That's enough to avoid pinch flats and provide decent rolling resistance, but works better with rough roads than higher pressure.
