The Nitto Ridge Grappler is Nitto's hybrid terrain tire — it splits the difference between an all-terrain and a mud-terrain, giving you aggressive M/T looks and off-road capability with A/T road manners. A variable-pitch tread pattern keeps highway noise down, while stone ejectors and a reinforced sidewall handle the trail. It's the most popular do-everything Nitto for daily-driven lifted trucks.
