They are not factory M1009 wheels. They are 16.5 inch wheels. You used to be able to get them from GM but I don't think they are available any more. Bottom line is, if you can find the wheels or 16.5" wheels that you like, they will fit no lift just fender trimming. The 36's can be dificult to balance, you will loose a little MPG's, they get flat spots when they sit for any lenght of time, even in the summer. They wear quicker than radials typical set gets 20-30K miles. But if they're a good set (evenly worn), and balanced well they ride just as well as any large offroad tire. They will make noise fairly loud, and they will bounce alittle at higher speeds (60mph +). They have been know to be out of round right from goodyear. That said for the money I think they are still a good deal. I don't know of any 36" tire that can be had for roughly $100. The 37" radials are nicer, but cost more and require that much more room. I have 11 of the 36's at my house right now in 85% or better shape all mounted on wheels 4 on aluminum the other 7 on HMMWV beadlocks and I don't even have $600 invested in them. Try even getting 4 chinese 36's for that. For now I will deal with the minor defects associated with these older bias ply tires. When the well dries up I'll either go to comercially available bias plys or radials. But again for the money you can't beat em. Especially if its a truck you don't drive everyday. I'd probably look to at least re-gear on a M1009 though. Thats alot to ask of a 10 bolt with 3.08's. Would be a real dog very under geared.
