havent read the entire post but i went from my 16" stockies to 17" (2005) with the bridgestone potenza re040 and i am experiencing drifting to the RIGHT

never used to happen with 16", and started to drive the moment i put the 17" on, also as i slow down, the drifting gets worse and actually pulls the steering wheel a good 40 degrees to there right just as im stopping.
