I have one factory bent AR767 black rim, 15x8, 5 on 4.5, 4" backspacing for free. I don't know the extent of "bentage," but it should work well for the spare tire. I ran a set of these but noticed issues that I thought were related to tire balance. Discovered I had a couple of rims that were bent since new. Anyway, I have one left and I'm willing to bring to Moab for anyone who wants it. It's free! Let me know.
