tire width plymouth duster

Running 15x8 4.25" backspace with 275/60R15
3/8" clearance to stock spring location, stock 8-3/4 A body rear.
Much more room to the fender lip, not at home so no exact number, BUT this also depends on your ride height. My springs are one inch over stock.






Here's an easy chart to understand backspace, because there seems to be some confusion in the posts above. More backspace draws the tire towards the leaf springs.
