Thanks guys, I'll get a picture of the whole truck when I roll it outside next, it has a much different look than it did with the black rims and 8X22.5 tires.
Don,
I am using 9R22.5 tires, which are about the same as 8.25X20 as far as width and overall diameter. Right now they don't rub the frame or springs, as the turning stops are adjusted right. But you can't learn much from that, as my axle is not stock, nor is it stock width. I actually goofed and narrowed it to much by about 1.5", thinking the 2 ton front track width was about the same as a 1 ton. I used the axle on my 1 ton for a while, and that was fine, eventually I'll narrow the spare axle I have to the right width, or as wide as I can and still look factory and fit the fenders, that will give the best turning radius I can. Then the axle under it now can go back in my 1 ton.
I expect these tires and wheels would rub in a stock AD setup, and the turning stops could be adjusted to keep it from rubbing.
