Pressure will depend on size, driving habits, and alignment. I'm running the 235/40/17's, alignment slightly more aggressive (more camber, about -1.5* front) than stock - soon to be MUCH more aggressive when I get her set up for autocross (over -2* and more toe out) - and I don't drive hard in a straight line much, but I corner like all hell (every turn is practice...). I run 37-38 in front, 34-35 rear. Harder cornering, more pressure to keep them from rolling under. Normal drivers with this size would run 32-34 front and 29-31 rear.
For "normal" street driving and the stock size (215/45) I would recommend 35-36 psi front and 32-33 or so rear. When I ran the 215's, I kept them at 40-41 front, 36-37 rear for hard cornering (larger tires use lower pressures, narrower ones higher).
