The hub is not offset or centered. One side is flush with the inside edge. The other side doesn't reach the sidewall of his tire. For my hand truck I had to buy 1 inch spacers to keep the tire from rubbing against the truck. As an aside, although the rim is split (and held in place by 4 bolts) the support tube/hub is not separate but welded to one half of the rim. Also flimsy compared to the old inflated wheel. I think I'll stick with Home Depot at $27 apiece.
