Rims and tires

You may want to try what I did when changing my wheels from stock 13's to 14's. Google - wheel and tyre bible pg4, then scroll down to the wheel and tire calculator chart. The chart will let you to input the original size tire and the new size and compare the tires for size and speed purposes. I did this and it helped me to pick the tires that would be best suited for keeping the speedometer as close to accurate as possible. I can tell you that the wheel sizes you have will fit because that is the exact size I'm using on my 66 Dart, as for the size tires you want, I'm not sure because mine are 195 60 14 all around and I'm quite happy with how they look and handle over the stock 13's.
