I havee a 2011 2500 diesel, about to put a leveling kit on. Do you guys thinks that a 305.60.18 will give me that bigger wider stance without being to small for the wheel well? or is a 325.60.18 the way to go. I have seen a couple guys with the same truck as mine and they had to do some serious cutting in the wheel well when they ran the 325's. I was looking at the mickey thompson ATZ. any ideas or pictures would be helpfull.
