15+16 inch tyre size for the impreza ! what will and what wont fit 1

[rabskyline]

going to get a set of 16 inch rims tomorrow from chris and wondered what was the best tyre size to compliment the cars looks and performance. i also have the jap tyres on the 15's and need to replace them but the ones that are on them are 185's and need to be a little broader. what can i safely fit ! would prefer to keep the 15's in the rally theme. ie, 225 /55/15 all weather type tyres and the 16's a bit stickier !

ive got 205/55 toyos on my 16`s, but think ur better with 205/50, but im sure some1 will correct me if im wrong, i only got the 205/55 cos i got them on a good deal.
