So I finally got my new wheels and tires installed today. 285/60/18 General Grabber AT2's on black XD Monsters. -12 OS and 4.5 BS. Will they fit? Yep! Do they rub? Yep! I can hardly turn the wheel without the tire chewing away at the truck. At this point, I feel like a big dually pulling a 30' gooseneck I have to swing so wide to turn. Really diggin the look of the wheels and the tires though. I think I made the right choice in both. However, its now time to get a 2" lift so I can actually drive my truck. I think with trimming the pieces its doable, but I am going to lift it first before I cut away at the affected areas. I hate to cut away that much of the body. Here are the results and pics of where its rubbing. Hope this helps in others trying to decide if you want to try it or not!
