71 Dart Swinger wheel/tire combo suggestions

You guys have some nice looking cars! I need to do other things before messing with any suspension. For now my stock setup works perfectly, maybe down the line :P

So I guess if I want bigger than 235 I need to go Rallye with more backspace. If steelies then 235 it is. Thank you all for your input, greatly appreciated. Definitely gonna save this post for later down the road
