I used 80 psi on the last ride, he suggested going to the high limit (100 psi). His primary concern was clearance for the larger chain ring, longer cranks - hitting the ground on turns, etc.
Based on the limited usage of the folding bike, I am not prepared to upgrade the rear wheel just yet; if I decide to keep it, make any investments, I will consider replacing the derailleur with an internal gear hub, and in turn, better wheel.
