I live in Wisconsin and roads here in the winter can become quite treacherous with snow/ice. I need new tires for my 2015 Lexus ES 350 sedan. My tire dealer recommended Michelin X-Ice3 and said I could run them year round. I'm also interested in the Viking Contact 7 as they are reported to be even better on snow and ice. Can I run these year round as well? Any thought or comments would be greatly appreciated.
