If you don't mind 'stepping up' a little, call your local big rig yard and ask if they have an 6 lug bud wheels. They will be 9 x 22.5. I purchased eight of them, six on the ground with two spares. Prices start at $25 and can go up to around $75 each.
I gotta tell you that you will then be running big rig tires. They ain't cheap but you will ONLY purhcase them once. If you have any questions, contact me.
I am hoping to put mine on the truck in the next couple of hours. IF the weather holds.
If that happens, I WILL post pix.
