The Nitto Ridge Grappler is a dynamic hybrid light-truck tire designed to bridge the gap between all-terrain (A/T) road comfort and aggressive mud-terrain (M/T) performance [6].Tread Block EngineeringZ-Groove Shoulder Blocks: Alternating Z-shaped deep cuts clear out loose mud, snow, and slush to maintain constant lateral grip [6].Block Foundation Reinforcement: Built-in heavy rubber foundations sit under the tread blocks to minimize tire flex, which improves highway stability and slows uneven wear [7].
