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.
Each Grappler has two sidewall designs so you can choose how your tires look. On the Trail Grappler one side has stylized lettering with V-shaped buttresses and the other has traditional lettering with flat buttresses. This feature was an engineering feat since even a small weight imbalance can cause unwanted vibrations. Nitto produces exceptionally uniform off-road tires even with different designs.
A common complaint with mud terrain tires is their noise level. Nitto's engineers set out to design an aggressive -- and yet quiet -- off-road tire. Using 3D computer simulation, Nitto's engineers were able to systematically adjust the size, shape and position of the tread blocks. As a result, Nitto produced an off-road tire that is 34% quieter at street speeds and 36% quieter at highway speeds.
