I have had the honor of purchasing a 2006 Dodge Durango ex-sheriff SUV. It is a beast but unfortunately it only looks like a house cat. Currently the shoes don't fit the man. I have way too much wheel well for a beast of such caliber. I am wondering if I can go from a 245/70/17 to a larger size tire to fill up more of the open space between tire and wheel well without having to change anything else about the SUV? I don't want to add anything to the beast other than tires if possible. I figured I better go right to the people who know best. So, any suggestions?
