MUD TERRAIN LIGHT TRUCK TIRE The Trail Grappler M/T blends some of the performance of the Mud Grappler with the on-road comfort of the Terra Grappler to create an off-road tire that is both aggressive and quiet. For off-road performance, the 3-ply sidewall and thick rubber construction increase puncture resistance. On the tread surface, the blocks provide additional biting edges that command lateral stability and enhance forward traction. For on-road comfort, Nitto's engineers used advanced sound analysis equipment to systematically reduce noise levels commonly associated with off-road tires for a quieter drive.
