Versatile Hybrid Terrain Performance. The NITTO Ridge Grappler A/T Tire combines the comfort of an all-terrain tire with the rugged capability of a mud-terrain tire. Perfect for trucks, it provides confident traction off-road while maintaining a smooth, quiet ride on highways. This hybrid design makes it an ideal choice for drivers who need performance both on and off the pavement.
Construction and Appearance. Featuring a dual sidewall design, the Ridge Grappler allows drivers to choose between an aggressive block appearance or a more traditional look. Its variable pitch tread pattern minimizes road noise, while shoulder and lateral Z-grooves improve mud evacuation and traction. Alternating tapered edges enhance grip in aired-down conditions, and integrated stone ejectors keep the tread clear for long-lasting durability.
Installation. Installation is easy and can be completed with standard tire mounting equipment. Most professional tire shops can mount and balance this tire without modifications.
Application. This NITTO Ridge Grappler A/T Tire fits 37-inch tire size - 37x13.50R18.
