What is offset.

       The offset indicates the distance from the center of the rim to the attaching disk part (unit:m/m). As seen in the attached drawing, the offset is indicated by "+" when the fitting surface extends beyond the central line of the rim and "-" when it is falls within. Caution is required to prevent the tire from coming into contact with the fender of the vehicle or the brake caliper if the offsets are very different.
