I have tried the Blizzaks and they do well in many conditions but studs (or chains) are the only way to go when it's 32 degrees. I had a set of Nokians with those funny-looking studs on my car and they were unbeatable but expensive. Now I have regular studs and when Blizzaks are sliding I still stop and go on the ice.

As global warming brings us more winter wetness, studs will once again be king.
