Atomic, check out
www.jegs.com and go to the tires and wheels section. You can order 5 of the Cragar Black Steel Wheel "Soft 8" design for about $37/each. They offer free 1-2 day shipping as well. There's nothing wrong with these wheels, and look almost identical to the Rockcrawlers you're looking to spend twice as much on. The difference is, the holes in the wheels are circular instead of the "D" shaped holes. A lot of people I know have run those wheels, including myself. For around $160 for 5 wheels, free shipping, you really can't beat that. They offer them in a 4" backspacing, which is a perfect backspacing for what you're looking to run as far as tires on your X.
