Careful, don't confuse offset and backspace.

Measuring backspace:

1. Place the wheel face down.
2. Lay a straight edge across the back of the wheel.
3. Measure the distance from the straight edge to the wheel hub mounting
surface. This is the backspace.

Offset:

A wheel's offset is the distance from its hub mounting surface to the
centerline of the wheel. If the hub mounting surface is outside the centerline,
the offset is positive. If the hub mounting surface is inside the centerline,
the offset is negative.

Measuring offset:

1. Measure the overall wheel width, outside-to-outside. (overall width is NOT
the inside bead-to-bead width)

2. Measure the backspace.

3. Offset = (Overall Width - Backspace) / 2
