Most mud tires do suck in the snow on the street. They're good in deep snow, but on plowed roads they're some of the worst. You need siping for street snow performance. The more biting edges on the tire, the better off you are. That's what siping does. That's why I thought those Cooper Zeons I had would be good in the snow. Holy hell, I was wrong. They were AWFUL.
