A bunch of people will tell you that a 275/60 is too wide for a 7 inch wheel, but i have run them for 10 years on 7 inch ralleys on a 73 RR. They look and drive fine. I agree that an 8 to 10 inch wheel would be better suited, but these are what i had and a smaller tire looks wimpy on a B body. If you want something narrower, go with a 70 series so at least you have some height to fill the wheel opening.
