There is a company that will make brand new steel 22.5s for big bolts. 10x7.25 in either a 5.25 or 4.75 center circle. The company is called wheels now. You may not like the price though, 385 each! I was and still am debating it for my big bolt. They will Make them in a 6.75, 7.5 or 12 inch widths, I was thinking super singles in the rear with the 12s and 6.75 fronts with skinny tires for easier steering.
