�I see these wheels listed as 5.75� wide sometimes and 4.5� wide other times. I wonder what it really is.
The 4.5" is from the inside to inside of the rim where the tire bead goes. �The 5.75" is outside to outside of the rim where the tire bead goes. �
There is a set of 15 inch wheels (they were optional on the CJ-3As) on eBay right now (ends May 18, 19;49 PDT). �The bid is up to $147 with $45 shipping for four. �Item number: 190677773429. �Like Carl said, that's half the price of new and the look to be in pretty good shape. However, if it matters to you, they are the CJ-5 style wheel. If you're not a purist the newer wheels may be even in better shape.
