Will 255/60/14's work on stock 73 swinger?

255's that's the same width I'm running on my 8 inch wide wheels, not sure if I'd want that much tire bulge. I ran 235/60/14 on my 14x6 and it looked good but if I were to do that again I'd have gone down to 225/60/14's. BTW when I bought that set of tires the old tires were 215/75/14's, I totally get what you are experiencing.
