you'll have no issues at all with 7.5 et25
225/45r17 recommended.
235/40r17 is possible, but check the allowed rim widths for the specific tire you're looking at BEFORE you purchase them. you may need additional front camber to prevent rubbing as well.
alignment is a must. without one, the car's induced front toe out will make the car feel twitchy.
