Post by: jonboy1216 on November 17, 2008, 05:15:50 AM

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

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!
