I only have driven about 10 miles on them. I haven't got my fenders finished yet. Did you have a lot of tire noise with them? It seems really loud on the back but I think it might be from my insides being a little to big? I love them though.
You can use the 3/4 ton stuff or you can machine down the insides of the 22s and make them set in far enough....or do what I do and raise the fender lip
