Backspacing is the key to running a big tire on a 67 Plymouth or Dodge. If you run an 8" rim you need 4.5" backspacing. The factory 8" rims are 4.25" this will be a factor. A 265/60/15 fits but is tight on the outer wheel well. 255/60/15 is a good fit. A 225/70 15 is a good fit all the way around the car.
