Tire sizes, AGAIN?

8” rims will accommodate a tire width from a 215 to a 245. I have 245/60/15s on 15” rims on my 65. I don’t know the width or bs because the rims came with the car. I can fit my finger between the tire and the quarter. There is some occasional rubbing so the next set will be 235s
If you don't know the width or backspace of your rims, you might have sevens. 245s will fit on sevens fine, imo. For an early A, the bs will have to be perfect! Yours must be. Cragar SS are famous for a "deep dish" look. It's a very attractive look, but often results in too little backspace. Without knowing what bs his rims have , I'm not willing to say they'll fit, and my experience tells me they probably wont.
