The Ridge Grappler tires by Nitto are engineered for all-terrain performance. They feature a dynamic hybrid tread design for quiet and comfortable rides on roads thanks to their variable pitch tread pattern. The lateral Z grooves and shoulder grooves in varying lengths and widths expel mud and slush for better traction and improve grip for better maneuverability. The step block edges and alternating tapered edges add biting edges for better wet and dry traction.
