Backspacing:determine how many inches your wheel goes inward.
Front spacing:determine how many inches your wheel goes outward
Offset: The offsets only determines how far the wheel goes inward. It plays a small part in knowing which wheel will fit. If one wheel mounting pad height is small with a short inner rim half and the other wheel mounting pad height is thick with a wider inner rim half, both wheels will have the same offset, except the wheel with the thicker mounting pad height will stick further out from your car.
Front spacing and Backspacing are very important when measuring 3pc wheels
