I have the same Kook tire on my 2500HD. I am really happy with them for what I do with the truck. Offroad traction has been acceptable, wear has been excellent (40K on them), snow traction is decent, and traction on ice has been good. On a side note I had dizzy female back into my rear tire on my 2500HD yesterday. She smashed her bumper in on her Camary but left me unharmed.
