69 Dart tire size

Well since this thread is all ready going and I think I know what size tire I need for the rear of my 1969 dart with a 7¼ rearend that I want 15" rims on so I need 4.5 bolt spacing 4½ BS for the rim with a 245/60R15 on them right? Stock springs now but I will be getting +2" over stock height after the new year
