i have a friend who had them. they are really a good light off-road tire. For anything around sharp or pointy rocks they are not the way to go. He ran over a rock that ripped his side wall with 15 psi off pressure in them. I ran over the same rock with 7 psi and did no damage and yes it hit the side wall not the tread. It shows they have weak side walls(2 ply i think, same as a passager car). The super swappers i have, have 6 ply. But for the money they are good, but if you plan on heavy off-roading then go with BFg's or super swapper. My 2 cents.
