If I had a truck, I would put the Dick Cepek Crusher on it. These are about the meanest looking off-road tires that Tire Rack carries. They have an aggressive tread pattern with large lugs shaped like bones. Continuing the bone motif, the Crusher has skull and bones logos on the side-biters. True to its aggressive image, the tire is available only in large sizes, most of them targeted toward lifted vehicles. It is not a tire for introverts, or the faint of heart, but perfect for your big 4x4.
