69 Dart garage resto

17" 5 spoke of some kind, still deciding. 225 in the front, I think I can get 245 in the rear.

You should be able to get 255's in there easy, and with an offset spring location kit, likely a 275. I'm running a 245/60/15 in my 66 Valiant that fits easy, and I have less rear clearance than you do.
