What Is Backspacing?


 While offset measures the distance from the hub mounting surface and the wheel’s centerline, backspace is the distance between the hub mounting surface and the inner edge of the wheel rim. The offset and backspace must be correct on a replacement wheel to ensure the wheel and tire assembly fits properly inside the well without contacting the fender, frame or any other components throughout its range of motion.
