I thought you put a straight edge across the back side of the wheel and measured from the straight edge to the back of the wheel where it would butt up to the brake drum. Are you doing something different? If I had 4 inches of backspace I would not be able to mount the wheel because the tire would hit the frame. Thanks!
You're doing it right. If the tire is wider than the wheel, the sidewall bulge needs to be considered in the off set too.
