The Trail Grappler?« M/T blends some of the off-road performance of the Mud Grappler?« with the on-road comfort of the Terra Grappler?« to create a 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?ÇÖs engineers used advanced sound analysis equipment to reduce noise levels commonly associated with off-road tires.
