"Backspace is the distance from a wheel's mounting surface to the back edge of the wheel in inches. By "back" we mean the brake side of the wheel. Offset measures the distance from the mounting surface of the wheel to the centerline of the wheel, and it is often indicated in millimeters. If the mounting surface is located closer to the street side of a wheel, then the offset is positive. If it is located closer to the brake side of wheel, then the offset is negative. If it is in line with the center of the wheel, then the offset is zero."

A: It is the distance from the centerline to the hub mount pad (where the wheel attaches to the hub). POSITIVE OFFSET - The hub-mounting surface is toward the front or wheel side of the wheel. NEGATIVE OFFSET - The hub mounting surface is toward the back or brake side of the wheels centerline.
