We strapped on a set of new DOT-legal 40x13.50R17 Nitto Trail Grappler MTs to our TrailReady wheels. They are actually closer to a true 40-inch tire than our old Goodyears. This made us happy we didn’t go through all the trouble of setting bumpstops, since they would’ve been too short. The 3-ply sidewalls will help keep us from sticking things through the tire. They are also a Load Range C tire, unlike most of the rest of the Trail Grappler lineup.
