Slick size

I just tried to fit a 31" tire in my about to be mini tubbed Demon and that will not fly. I am also going to have to use a 28" tire unless I want to stretch the wheel well openings. I will be running a 28x10.5x15 tire in my car. Unless you want to do a full back half that is about the most tire I would really forsee you being able to run.
