I have about 5000 miles on mine (stock size, P-Rated). I have had zero complaints on the road, dry, wet, or very heavy rain with standing water. I really can't tell the difference between them and the stock tires. I had them up in the snow this past weekend and they did great cutting fresh ruts in heavy wet snow that was occasionally up to my skid plate. I could motor along nicely in just 4hi, with no tech gizmos active, and I never really felt a loss in traction unless I mashed the throttle, even in some places where I know mud is under the snow (most was snow over gravel on logging roads). I easily could have gone much deeper if I was willing to plow with my bumper. The real evidence was that my wife never got nervous.
I think these are the best tires I have run for a combination of onroad/offroad/snow that isn't a mud terrain or something more extreme. Haven't had the opportunity to try them out on ice.
