It may be the same thing ,I'm selling my rims i took off when i bought a set of rims and tires off a rubicon and someone replied asking what the bolt pattern and offset was to see if they would fit his dodge pick-up

Offset & Backspacing are different. Usually people are more concerned with backspacing
Backspacing is the distance from the back of the rim to the mounting surface of the wheel, the offset is the distance from the mounting face to the centerline of the wheel.
