I don't think I have seen these before by pro comp. I notice they come in 6x4.5, maybe these are the wheels pro comp claims will fit the 05-06 Xterras without spacers. Im not interested in them, but someone might want to look more into it?

I am not sure if they are new, but I went back and looked at the 8089 model, and the description for that is the same " high offset brake clearance for today's performance trucks and sport utility vehicles. ". A few months back, when looking at these wheels, I think the determination was that they would NOT work.

Maybe someone should try them. However, the offset and backspacing do not match the stock specs, so I presume that they will stick out from the Xterra about 1 inch more than stock or even the Gunner 6s that I bought.
