Nitto Ridge Grappler Tires Nitto Tires presents the latest addition to their Grappler lineup―the all-new Ridge Grappler tires! With their edgy M/T appearance， on-road performance of a traditional A/T， and two different sidewall choices， Ridge Grapplers pack many features into a multipurpose tire. Several new perks include: a reinforced block foundation for reduced flex of the tread blocks; alternating shoulder grooves to clear mud; stone ejectors to prevent damage from stone drilling; and a lateral Z-groove center tread pattern―providing exceptional biting edges for traction. With load ranges from C through F， Nitto Ridge Grapplers can be installed on any light truck and not lose any towing capability. That truly makes them hybrid tires!
