I've seen guys running SD axles with 16.5 rims and if ur running h1s you can have any pattern you want, the reason I don't know if can run 16.5 is I think the brakes got bigger in 05
I run the 16.5 Mickey Thompson Classic II's on my Excursion. Military tires don't really last that long. The 16.5 Rims are hard to find and Most companies have Quit makin them. I have one that cracked and I needed a replacement for it and couldn't find one. So if you go this way you will be limited.
