OK I did a lot of measuring and also allowed for some room. Nothing worse than taking a sharp turn, or hitting a dip and hearing the tires scrap in the front or rear. So this is what will fit on a 64 Dart and allow room and provide less steering effort etc.
When you call Newstalgia Wheel 1.800.281-2819 ext 306. Talk to Shawn. He is handling the orders.
I went with:
15x7 rear rim with a 225/60-15
15x6 frt rim with a 205/60-15
The 225 in the rear with stock ride height is fine with these rims spacing, a 235 would fit with stiff spings, a raised up body with hangers on the springs or air shocks. On the front I liked the size of the 15" rim for disc clearance issues the look etc. Also with the 6" width and the 205 it is less tire to turn, allows plenty of room for turning etc.
I have stuffed a 215/60 on a 14" which is a little shorter, but is wider. I think with the suspension mods and front and read sway bars the Dart should handle pretty good for a 64!
At issue: if the axle was narrowed or you could get more backspace on the rim you could fit a 235. 15x8 gets a little more space. The issues is the front of the rear wheel well on the outside edge. I have a GT and with chrome molding on the front of the well it is right up to the tire on a 235. :thumbup:
