I had NDT's on my Army Land-Rover. They do drift around a bit, and don't like to go more than 50 mph. They do however, do quite well off road, and in deep sand and mud. Before that it still had the Nato tires, the Michelin X, with steel belted sidewall. What a pain in the [censored] those were to mount! The newer tires wear better, and are stronger, but they don't look as cool, and don't make as much awesome tire noise! I loved those NDT tires.
