Widest FRONT tire on a '66 Dart

Been searching,and I have a good idea how big I can on the rear of my dart,but not the front.

Is there a general consensus? The '66 is my daily driver,and like to run the same size on all 4 corners, but would also like to go as wide as I can.

I was looking at a 225/65r15, or maybe a 60's series if I can get it. Too wide? To tall? any experience would be helpful.

On 15's stick with a 60 series.
What look/type car are you going for ?
Drag,Street,Canyons,Groceries,ect ?
As usual,back spacing will be key.
What to you have in mind for 15"wheels ?
Do you still have the small bolt pattern ?
Slant six or V8 car ?
