Why choose the Nitto Ridge Grappler in 37X13.50R17?

• Built for lifted heavy-duty trucks, full-size off-road builds, and high-clearance custom rigs: The 121Q E2 rating supports heavy-duty trucks, towing, hauling, overland gear, and work-ready payloads.

• Hybrid terrain performance: The Ridge Grappler blends all-terrain road manners with mud-terrain-inspired bite for drivers who split time between pavement, job sites, trails, gravel roads, and weekend adventure.

• Quiet, comfortable road manners: Nitto's hybrid tread design is engineered to reduce pattern noise while still giving the tire an aggressive stance on trucks, Jeeps, and SUVs.

• Confident off-road traction: Alternating shoulder grooves, staggered shoulder lugs, and deep sidewall lugs help the tire grab loose terrain and add durability-minded sidewall presence.

• Rugged truck styling: The Ridge Grappler gives daily-driven pickups and lifted builds a bold look without giving up the on-road usability many drivers need during the week.
