As far as the report, I have about 300 miles on them now. I dont drive on asphalt much, but they were fine when I have. No snow or ice yet (texas), and they are ok in mud, not bad or great. The only time I've been stuck was when I was buried to the skid plate, noone else could make it through either. Everyone had to winch. They were pretty impressive on the rocks at barnwell mountain. I did get one cut on the sidewall that didn't go through and pinch flat. I had 10 psi in them since that's the recommended pressure for rocks (on the sidewall). Probably wouldn't have happened with more pressure.
