Just wondering if anyone has had either of these tires on snow and ice yet. The Winterforce have been around a long time but there aren't any reviews on the X-Ice in snow yet. I was hoping someone here might have used prototypes last year. I do not want to run studs, the winterforce is drilled for them so that makes me wonder if it needs them to be of any use on ice. The choice might be made for me anyway since the X-Ice tires in 215/70R16 still haven't landed here and if they keep saying one more week much longer it will be spring.
