wheel fitment on 65 valiant

I put together a couple of 65 Valiants and a 66 using the very combo you list. All the cars were lowered slightly with big sway bars front and rear. Using MOPAR cop 15x7 wheels the 235 rear and 205 front tire sizes were the absolute max in stock fenders. You might even find that different manufacturers of tires with those same sizes will vary enough that some will interfere. I suggest making a deal with the tire store to take back any tires in trade for different ones if there are clearance problems. Good luck!
