Pancho, quit with the recomendations on sizes that will throw everyone's speedometer and odo off. For some people, 215/55R16 would lose way too much steering response. Finding the right tire is a wiser decision than changing the size to compensate for a harsh ride.
225/50R16 is my recomendation. 205/55 and 225/50 have almost the exact same diameter. Most people that rub using 225/50 on E1 rims rub on the inner plastic fender lining, not the strut. 205/55 would do the same then. I have seen, ridden, driven in 225/50R16 Kumho 712 on a 2000 SVT. Under moderate cornering, the left rear tire would rub the fender. So, he just mananged to pull it back a little with some zip ties. 225/50 should provide batter handling and performance vs. 205/55.
