    Looking to confirm 15x7 steelies 63 series Wheel vintiques with 4 inch back space fit. I have a 69 road runner and want to make sure there is no rubbing or fitment issues. Pictures would be great if you can provide some.
    Hope everyone is well.
    Thanks to my b body friends for all your help.

    I believe most 15x7's have a 4.25" backspace. They will fit both front and rear on your car with no issues.

      I had 235-60x15 on stock mopar 6"steelies with 4.25 bs, that rubbed (something?) on the inside, letters only, one side only! With your four inch backspace, should be good on the front with that size, could go larger on the rear.

        The problem with your 235 on a 6 inch rim , you are creating more tire bulge on that 6 inch rim , than there would be by using a 7 inch rim ( same backspace ). So it would rub on a 6 , but not a 7 inch rim.
        I did a test , 275-60-15 , on 15 x 7 and 15 x 8 wheels , same backspace. Tire rubbed when mounted on the 7 and not on the 8. Tire bulge was the difference...

          To be perfectly honest, I have used that wheel/tire combo on both my roadrunner and my 62 savoy. There is a decent chance that what the tire was rubbing on was the hooker header tube in the wheelwell of the 62, maybe not anything in the runner. What surprised me was that it rubbed only on one side. (Rear-most header tube on BOTH sides exits through fenderwell, then loops around chassis, back under the car).
