As of early 2016, Nitto's Terra Grappler tire specifications include 20 different wheel sizes that are available over five different diameters, including 16, 17, 18, 22 and 24 inches. Each version of the Terra Grappler tire has different overall diameter and width dimensions and is rated for a specific amount of maximum load in pounds. Each tire size type also has a different maximum pressure rating and unique stock number.
The Nitto Terra Grappler includes various design features such as dual sidewall design, high density siping, shoulder lugs for off-road performance and lateral angled voids for performance in all weather types. The tire's dual sidewall design allows buyers to customize the visual appearance of their wheels. The Terra Grappler tire uses a combination of solid outlined and serrated lettering on opposite sides.
The Nitto Terra Grappler tire uses a design where its tread pattern void ratio attains a balance that helps drivers with both on-road and off-road traction and handling. Each wheel's surface also uses a series of coupling joints to increase steering response of the vehicle. The surface of the Nitto Terra Grappler utilizes high-density siping that is made up of both lateral voids and deep sides to help the wheel effectively move water away from its surface.
