About the Nitto Ridge Grappler

The Nitto Ridge Grappler is a hybrid rugged-terrain tire built for light trucks, Jeeps, and SUVs that demand serious off-road capability without sacrificing everyday drivability. Sitting between a traditional all-terrain and a mud-terrain design, it delivers aggressive traction in mud, dirt, rocks, and sand while remaining composed and reasonably quiet on the highway.

The Ridge Grappler's symmetrical tread combines a high void ratio with wide channels and alternating shoulder grooves to expel mud and debris efficiently. Reinforced block foundations add tread rigidity, stone ejectors guard the casing from rock damage, and stepped block edges improve wet and light-snow grip. Computer-optimized variable tread pitch reduces noise-generating frequencies for a quieter highway ride. A dual sidewall design — smooth on one side, textured 'lizard skin' on the other — lets owners choose their preferred look. Coverage is backed by Nitto's limited manufacturer warranty: full protection through the first 25% of tread wear, then pro-rata coverage down to the final 2⁄32".

Key Features

• High void ratio tread evacuates mud and debris for consistent traction

• Alternating shoulder and zigzag grooves enhance off-road grip
