Will these wheels work on my '66 Dart, max tire size?

I have found a wheel with the following data

15x8"
4,625 backspacing
+3mm Offset

Will these fit back on my '66 Dart 4-door, 8,75 rear and stock springs and wheelhouses? What size tires to use if they do fit? How big diameter to aim for to keep em from rubbing and how wide? I'd like as wide as possible without rubbing and just wondering if anyone knows or can hint me in the right direction?
