Widest width Tire, Front/Rear on '65 Dart

Anyone know what is the widest tire I can safely go without rubbing on the front/rear of my Dart?

I was thinking 235-60 14's on Front and 245-60 15's on rear. Any idea if this will work?
Rear yes, front I don't know. I have 205 60 15 on front and 245 60 15 on rear of mine with plenty of clearance!
