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.
Tread Block Arrangement
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.*

The 3-ply sidewall with a high turn-up construction acts as an extra layer of reinforcement to increase puncture resistance.
Nitto’s proprietary, automated manufacturing system produces extraordinarily uniform tires. This creates a smooth ride on paved roads.
Reinforced shoulder grooves adds additional off-road and all-season performance without compromising tread block stiffness.
Deep center sipes decrease hydroplaning and increases traction in wet conditions.
The balanced void ratio efficiently removes mud and dirt from the tread to provide continuous off-road traction.
