Hey guys, just with making the transition to a smaller folding bike, I finally got my Schwalbe Marathon's mounted (thanks for all the help, guys + sporting life!) and they got about 75psi in there now. I really enjoy the ride and low rolling resistance, but its on a 16" wheel and was wondering what everyone else runs? no creaks or squeeks in the frame and things seem to be good.. anyone run 100 or more?
