I am also running the ATR's, but I have them on Douglas rims, have had no problem with air leaking out of them, as far as wear they are good at 400 miles, of course that isin't alot.Now as far as snow we hardly ever get any so I cannot answer this one, but in mud they surprised me,I was quite impressed by the way they pull. I will have to agree with the other gus about the tire for the rincon, although it may seem to be stiffer it handles alot better, you do not have all that tire roll, hope this helps
