Offset?
Could somebody explain wheel offset to me. I thought it was the deviation from center. Such as an 8" wheel with no offset would have 4" backspacing. Recently at Disco Tire, they told me that the 8" wheel I was looking at had zero offset and 4.5" backspacing. Now I am confused.
Thanks, Brett

You are correct in both accounts. Confused even more? Wheel width is measured from the tire bead surface to tire bead surface. Backspacing is measured from the wheel lip which happens to be around .5" out from the bead surface. That is where the extra bit comes from.

I have an unlimited budget. That bad part is I have already used it up.
