I love the description on NTW's site http://www.ntwonline.com/Bias-Ply-Bu...dder-C414.aspx
If you are looking for a long wearing, quiet, good riding tire, this tire isn't for you. If you need great traction in a tough off-road tire, then you have the right tire. The deep aggressive lugs clean themselves in even the deepest mud and provide excellent traction in any terrain. These things howl like a banshee, take a ton of weight to balance and aren't the roundest tires in the world but you can't beat them for off-road use.
