I've seen a number of posts of people trying hard to find the factory Alcoa dually wheels, and curious what the draw to these are...is it just the rarity of aluminum dually wheels? Just liking that particular look? Do they give the ability to run larger/wider tires than the steel wheels? The thought came to me recently when I saw an almost complete set of the 5 spoke wheels for sale locally - 3 aluminum, 2 steel...I did think they would look good on the truck, but only being 3 aluminums - bummer..but it did make me wonder if that might be the way to get 245/75R16 tires on the truck without having to run spacers? I've heard there is some wheel that I can get that will clear a 245. I have a virtually brand new set of Michelins on my Chevy that are 245/75R26, and I'm getting ready to sell the Chevy. But my F-350 needs new tires on it. I've read that 245/75 tires won't fit well on the duals in the back due to wheel width/offset when loaded down, and my truck will definitely carry a lot of weight on the bed.
