I have a 74 dart, it currently has 14" wheels and tires (steel wheels). I am planning on buying a set of cragar s/s wheels for it, i would like to put 15" wheels on it, but am unsure of the fit. Does anyone know what the largest /best combination of wheels and tires will fit without rubbing?

Sure,, the rears can be as wide as 7" with a 4 1/4" or 4 1/2 backspacing.
Front of the same size will clear no problem. I like to run 235/60/15 on the rear with anything from 205 to 225 for the front for a nice look.
This is conservative with out having to worry about rubbing.

thanks for the reply. I am debating on getting a set of cragar s/s wheels for it, either that or paint my stock steel wheels and get the dog dish caps. I dont know yet.
