I had the same problem. I talked to someone at M.E. Miller Tire and I bought a new rim and used the old 22" centers and fabricated a 24" wheel. You need to watch your offset, tire width, and the tire diameter especially on a 4WD. It's not the prettiest thing in the world but woks fine as long as I keep it under 100 MPH. The cost is probably a wash the first time. Now I can buy 24" tires which are easier to get (and cheaper too!).
