I've seen guys here say that they're running a 1/4 inch spacer between their rear duals to run a wider than stock tire, something like a 245/75R16 to replace the factory 215/85R16. Given that these duallys are hub-centric, and depend on the wheel/hub fit to center the wheel because the flat-faced lug nuts won't do it, how does a spacer like that work? I know the larger spacers have the lip on the spacer to properly center the outside wheel, but I've never seen a smaller spacer with that lip.

My truck has tires that are in desperate need of replacement...I'm actually surprised that cords haven't popped through yet. I've been searching for the 5.35" offset 4x4 C&C dually wheels, with zero luck so far. In the meantime, I have a virtually new set of 245/75R16 tires just collecting dust, but mounted on Chevy wheels, and I know they won't fit on the wheels I have now without a spacer. I figured a 1/4" spacer should be relatively inexpensive, but as I said, I've never seen one with the centering lip. Is there enough "meat" on the hub to handle two wheels and that spacer? Am I just not looking in the right places? Are people just running these spacers without the lip and getting lucky?

Have you sorted out your question about Dually Wheels? Also, have you also purchased a new set of tires?
