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).
The easiest way calculate wheel offset is as follows: First, measure the overall width of the wheel (remember, just because a wheel is 18Ã7.5, does not mean that the OVERALL width is 7.5â. It means that the measurement between the outboard flange and the inboard flange is 7.5â). Next, divide that width of the wheel by two; this will give you the centreline of the wheel.
