I didn't know this about 16.5" wheels before. I will keep my eyes open for a deal but I'm not going to worry about it. The only off-roading I do is mild stuff to get out in to the boonies. I think I found some lug nuts so I'll order those and see how it goes. If it fits I'll call this project done until I run into a to-good-pass-up deal on some replacement wheels.
