Yo! I jumped from 205-55/16 Pirelli P7000's...to a set of 215-45/17 Dunlop SP sport 8000's. The handling difference was very noticeable...but also very expensive. If you dont have a set of rims that you are drooling to get, you might be able to skip it altoghether. just more flimsy advice... Mike '96 A4q
