17" Steel charger wheels on dart, Rear tire size?

Ok so I got a set of 17 " tires and wheels real cheap off a Late model charger. 2 have 215 65 17. bolted on the front and way too big. haven't tried the rear yet. Think I'm gonna run 225/50 or 45 on front. Ive seen pics of these on a duster, anyone running them on a dart? Gonna paint silver and put the rally centers on them. Thanks
