The Ridge Grappler is Nitto's hybrid tire, blending an all-terrain and mud-terrain tread into one design. It aims to give aggressive off-road traction with a highway-quiet ride, using staggered shoulder lugs, lateral Z grooves and stone ejectors. It suits truck and SUV owners who drive daily but still hit dirt, gravel and mud on weekends. Against pure mud-terrains it is quieter and more street-friendly; against mild all-terrains it grips better off-road but runs heavier and louder.

Owners of the Ridge Grappler generally praise its balance of quiet highway manners and strong off-road grip, and many like the dual sidewall look. Some note it is louder and firmer than an all-terrain and wears faster under heavy towing.
The Nitto Ridge Grappler is a hybrid tire that combines features of mud-terrain and all-terrain tires. This size is 37x12.50R20. Its hybrid tread pattern is designed for a quiet, comfortable ride on the highway and for off-road use.
The tread pattern was developed with advanced sound equipment to keep highway noise down. Shoulder grooves alternate in width and length to clear mud and maintain traction. Lateral Z grooves sit in a zig-zag pattern to give biting edges for traction.
A reinforced block foundation adds rigidity to the tread blocks to reduce flex. Stone ejectors protect the bottom of the groove from stone drilling. Staggered shoulder lugs add off-road traction. Dual sidewall designs let you choose how the tire looks.
