The front fenders on Dodge trucks have the inner fender curve down all the way to the wheel opening. Yes they would have to be cut to make the wheel opening bigger. I've heard that if the inner fenders are not secured to the fenders, it seriously weekens the front end structure. Looking at my truck I believe it. Unless it is done right, I think it would really hurt the truck. How big of a tire do you want to run anyway?
