I've had my Toyo Proxis II's for just over a year now and they have been quiet and wearing well. I had only had some limited snow feedback until this last week. Needless to say they have done very well in shallow and deep snow. The deepest that I had to trudge through was about a foot and the X did great with the Proxis. Since I don't hang turns and the X serves as my winter car I did opt for the siping so that may be aiding me in snow and ice traction. Hope that helps.
