The owners manual and the sticker on the bike, recommends 36 psi rear but the tire sidewall states 33 psi max. I've never seen a manufacturer recommend a higher pressure than what the sidewall reads. For now I'm going with the Michelin recommended pressure at 33 for the rears and the 29 psi for the fronts. I weigh about 180 lbs. What psi are you guys running? Yes I've searched and didn't find a thread on manual vs sidewall.
