Tire Size Question

[146200]

I have a 1981 Malibu with a 10 bolt diff out of a 1967 Chevelle. No modifications have bee done to the frame rails. I have a set of 15" rims with a 4" back space. Does anyone know if a 2556015 tire will fit without a rub? If not, could someone suggest a size? Thank you.

i am running 255/60/15s in the rear with the factory olds rally wheels SSIII I believe it has a 4.25 back spacing. I had to run a 1/4 inch spacer because it was a little to close to the inner frame rail, but mine doesn't rub at all.
