I have no experience in the snow yet with mine. I would think the tread pattern would be ok but its a skinny tire with little sidewall flex so when you air down for the snow I don't think it will help much. IDK but I think the stock bighorns would probably work better.
I'd say they are more a desert/trail & rock tire. They are pretty tough, I have used them out in the desert, mountain trails & some rock crawling without putting a hole in them or damaging a sidewall yet. They aren't very good in the mud & kinda feel they won't be very good in th snow either.
