Nitto Tire U.S.A. says the new Exo Grappler AWT tires provide superior traction in dirt, rock, gravel, snow and ice and are available in two unique sidewall designs to customize the look of a vehicle. The tires are designed specifically to deliver consistent traction on dirt trails, gravel and farmland, while providing driving comfort when cruising at highway speeds, according to Nitto. A new chip-resistant all-weather compound, three-ply sidewall construction and large, thick sidewall lugs contribute to superior puncture resistance and winter traction capabilities. Exo Grappler AWT tires are available in the most popular 17-, 18- and 20-inch rim diameter sizes.
