Here's the info from their site: The two parts that would keep me from buying this tire are the tread depth and the load rating for the size you need. If you are buying these tires for off road use, it may be better to go with the mud grappler if you want to stick with Nitto.
Many run the Toyo's and love them. Since we have snow here, i went with a Procompe Extreme AT tire and love them.
The Dune Grappler satisfies the enthusiast who wants an aggressive tread for off road capabilities, while providing a more comfortable and quieter ride on the road. By utilizing advanced computer simulation technology, the Dune Grappler's tread block arrangement reduces high levels of noise commonly associated with aggressive tires, while still providing a traction-oriented tread for off road use.
The Dune Grappler Desert Terrain tire is offered in higher load range ratings of ?D? and ?E' in certain sizes. These higher load ratings make the Nitto Dune Grappler Desert Terrain capable for use with heavyweight trucks, such as Ford Super Duty and GM Heavy Duty, as well as other large and mid-sized trucks on the road today. "LT" sizes will be available with a 3-ply sidewall construction for increased puncture resistance.
