The Nitto Exo Grappler AWT (All Weather Traction) is built to meet the all-weather demands of off-road truck enthusiasts. Whether their journey takes them through off-road trails, gravel, or farmland, the Exo Grappler AWT is built for 4-seasons of 4-wheeling. Featuring an all-new chip resistant all-weather compound, 3-ply sidewall construction, and large, thick sidewall lugs, the Exo Grappler AWT provides armor for the elements. The gear shaped block edges reinforce center tread blocks and provide a stable contact patch. They also help reduce stone retention and stone drilling. With computer analyzed tread block arrangement that reduce tire noise normally heard at highway driving speeds. The staggered shoulder blocks provide biting edges for off-road traction in loose dirt surfaces. The 3-ply sidewall with large sidewall lugs offer additional sidewall strength and puncture resistance. Each Grappler has two sidewall designs so you can choose how your tires look. On the Exo Grappler one side has three-dimensional butresses and the other has Y-shaped butresses. This feature was an engineering feat since even a small weight imbalance can cause unwanted vibrations. Nitto produces exceptionally uniform off-road tires even with different designs. A special mix of natural rubber, high strength polymers, and wear resistant materials aids cut and chip resistance on unpaved gravel roads. Spiral shaped stone ejectors serve to reduce stone retention, as well as stone drilling. Rated with the 3-peak mountain snowflake for winter driving conditions, the Exo Grapplers sipes and large lateral grooves provide biting edges as well as water and snow/slush evacuation. These tread features are combined with a new durable compound that allows for traction in freezing temperatures. For additional traction, option TSMI #15 studs can be added for increased winter traction.
