As of 2015, some features of the Nitto Grappler tires include a dual sidewall design, high-density siping, and improved traction and handling for the driver for its Terra Grappler model. The exact characteristics of Nitto Grappler tires depend on the model.
The dual sidewall feature prevents imbalance on the tire that can lead to unwanted vibration while driving. The high-density feature allows the tires to push water away from its threads, which reduces the chance of hydroplaning across a surface. The multipurpose traction and handling aid in reducing flex and provide superior traction, allowing the driver to experience better steering response.
Nitto Tires U.S.A. makes the Nitto Grappler product line of lightweight truck tires, including the Mud Grappler, the Trail Grappler, the Exo Grappler, the Terra Grappler and the Dune Grappler.
