The Dune Grappler® has a unique tread pattern that was engineered for both on-road comfort and off-road performance. The sidewall lugs and 3-ply* polyester sidewall construction add protection to help prevent sidewall punctures. The tread block arrangement reduces tire pattern noise commonly associated with aggressive tires, while still providing a traction-oriented tread pattern for off-road use.The contact patch and moderate void ratio offer balanced traction in varying terrain. Select sizes are available in higher load ratings to meet heavyweight truck demands. The Dune Grappler® is engineered to be tough - both on and off the pavement.
