rear wheel size and backspace

[jonboy1216]

what is the largest tire and rim combo can a stock 68 non tubbed car hold without rubbing?

[PANTHER-BUFF]

I have 17 x 7 fronts with 4.5" backspacing, 17 x 8 rears 4.75" backspacing, backs rub slightly when car gets twisted on incline - no biggey

Try this:

I have 15x9 Pro Stars, 4.5" backspace with 11.5x28 Hoosier street slicks on mine. The tires kiss the inner fenderwells on turns, but like buff said--no biggie. A 1/2" spacer would cure it easily There is plenty of clearance at the outer lip, where all the trouble is usually caused by positive offset. Hope this helps!
