I ran 225/45-17 on my winter setup and the ride was definitely more comfortable but it didn't look nearly as good as the car sitting on 18s.
Well, my car is currently sitting on the 17" Z4 winter rims, since the previous owner "forgot" to return the summer rims when he returned the car due to inability to pay for it. Consequently, right now my tires are 225/45/17 all around.
