Wheel offset with WM3 rims

powerdoc said:

My WM3 rims are on order. I haven't dissembled my old rims yet as I need to measure offset first. When reassembling new wheels do I simply subtract 1/2 the extra width of the new wheel from the old offset to get the new offset or is there something more arcane that I should do?

Thanks! Always thought it was from rim edge to hub.

Offset is measured from the middle of the rim to a repeatable and reliable outer hub surface (such as the flat disk carrier surface, etc). Your new rim width will not change your offset calculation, assuming you are measuring from the middle of the rim.

Surely you'll get the same result, or am I missing something?
