Scrub, or steering offset is the difference measured at the ground between a line drawn vertically through the center of the wheel/tire and a line drawn through the king pin axis with the vehicle viewed from the front or rear. If the wheel/tire centerline is outboard of the line drawn through the king pin axis, as bone has done here, positive offset is achieved. If the wheel/tire centerline is inboard of the line drawn through the king pin axis, negative offset is achieved. Ideally these lines will intersect at the ground under the center of the tire as viewed from the front or rear of the car.
