Might be a touch sticky-outy (so to speak heh) and will probably catch the arches on the rear. They also on the big side tbh. I would think smething like a 205/5516 will be somewhat stretched but do-able, a 225 would sit better but you'd need a very low profile. Something like 225/40 16 - not so cheap, more than most 17s. Only way to know is try it.
For the record 205/50 16 on a 7' rim is perfect for an S12.
