if on the track i run 29-31 front and 28-30 rear. (lower in the wet or when really hot weather). on the street i'd stick to 34-36 front, and same in the rear if solo, and 38-40 if two up.
because of the structure of the tire, it allows more flex, and better feel, but sacrifices rigidity, a few lbs of air pressure give you back the rigidity with not too much penalty in the feel and ride quality.
