Wheel Offset. Wheel offset (abbreviated ET) is the distance from the mounting surface of the hub (M) to the wheelâs centerline (C). Offset can be positive or negative and is typically measured in millimeters. Wheel Backspacing. This is the distance created between the plane of the inner rim and the mounting surface of the hub (M).
Most stock wheels have a positive offset. When you go to a larger tire, the wheel backspacing needs to change so that the bigger tire won't contact the aforementioned items. Most often, when switching to aftermarket wheels this means that you'll be using a wheel with a negative offset. Naturally, this creates room for a larger tire.
