I live in New England and have used all-seasons for decades. I finally decided to get real snow tires...these Blizzaks are amazing. My first drive in snow was today, about 6 inches of thick wet snow. People around me were spinning, stuck, sliding but my Camry felt like a Hummer. These tires chomped through everything flat out astonished me. I had no idea modern snow tires made such a difference, most of the time the road felt like dry pavement, the worst spots felt like I was driving on sand.
I plan on switching back to all-seasons in the spring and keeping these in the garage. BTW, based on today's experiences I just purchased a set of these for my Corolla.
