I had x-ice tries on my old subaru outback sport and I loved them. Last year I bought another set of x-ice for my full size subaru outback and I have been really disappointed in their performance. I slide on slushy snow. I don't have much traction on ice and when I attempt to drive slowly over packed snow that has turned icy, I slide all over the place -- even with AWD. I finally caved and bought hankook W409 studded winter tires because I couldn't trust the x-ice on my daily 20 mile commute. I'll put the x-ice tires back on in the spring - since it rains nearly year round in southeast alaska.
