My Berlina was lowered, came with 195/60-14 on a 5-star Performance rim, so a bit shorter than 65s, but I thought I'd share. The tires rubbed (not enough offset), harsh ride, had to be very careful not to bump the sump gaurd, and tires had a tendancy to want to turn into the curve more than expected. I now have 185/70-14 on the very same Cromodoras you mentioned and there's no rubbing, steering is much more predictable and the ride noticebly smoother. I'm very happy with the change.
For what it's worth, my godfather of sorts used to be a brake and suspension specialist, worked on quite a few Alfas including those raced, and told me to only use 185/70-14s (with a stiff side wall). My recollection is that it was his opinion that if you wanted better cornering you're better off focusing on a well-tuned suspension system than adding wider tires.
