I have 15 x 8 in the rear, and 4 1/2" backspacing, and I have A LOT of rub on the lip after beating, and bending (going to replace the lower wheel wells anyway). You really need a 5" backspacing. I am also running a 275-60r15 in the rear, it's the biggest that I could fit.
Here's what is ideal for a 65 Malibu SS Rear rim: 7? with 4.5? backspacing Rear rim: 8? with 5? backspacing Front rim: 7? with 4.5? backspacing Charles ------------------------------------------------------------------- Check out my 502 powered '65 Malibu Super Sport Project http://www.65ss.com > > > Would running 15" wheels affect these any of these specs? > > I'm contemplating 15x8 with 4 1/2" backspace in back and the same with > probably 4" or 4 1/2" backspace in front.
