I run Blizzak WS80 Studless tires in the winter. I get around great in my Cruze. I've driven through snow that the front bumper plowed through with no issue. I've also driven on total black ice roads several times and while I had to drive very slow, I never had an issue with traction. That's really saying something considering where I live is all steep hills and sharp bends. I don't think I'd consider studs with how well the Blizzaks work.
