I have seen several people running 275 15 tires on 65 B-Bodies. It doesn't look possible to me without messaging the inside of the wheel wells? I have a couple sets of the 15" x 8" Mopar steel wheels I would like to run on the back of my 65 Coronet and my 64 Polara. I know that I will have to have Stockton Wheel change the offset on the wheels. Does anyone know what the back spacing and what it takes with this combo?
