that picture brings up a good point I have beent hinking abuot for a while, and I have only seen this here. its not that relevanto to the post but Ive been wondering about it.
backspacing is obvious, hub to back side of wheel.
off set as far as Iknew was the distance from the center ot the whel to the hub face of the wheel + or-. so in theory that 9. 5 inch wheel with a +22 offset should actually have a backspacing of 5. 616. I dont understand how you can have a different offset and the same backspacing on the same width rim. it doesnt make sense. well to me, some one please tell me if I am wrong
