Nitto's Exo Grappler AWT is designed for true four-season traction, with a durable tread compound that mixes natural rubber, high-strength polymers and wear-resistant materials for flexibility and traction at subfreezing temperatures. The aggressive lug tread features staggered blocks with a dense network of sipes and extra biting edges, and is pre-drilled for easy installation of studs, earning it the Three Peak Mountain Snowflake rating for severe winter service. Stone ejectors protect the casing against damage from rocks, and a 3-ply sidewall with large sidewall lugs guards against punctures and cuts. The tread pitch of the Exo Grappler AWT is randomized and computer-tuned for low road noise, and like all Grappler tires, the Exo Grappler AWT features a plain black sidewall on one side and "lizard skin" texture on the other, making it easy to customize your truck's appearance.
