I put these tires on in early December and have driven 2,500 miles on them in the last month including a trip to Minnesota & back. Part of my driving has been on dry roads, but most of the miles have been under some really ugly conditions including; a blizzard, 8-12 inches of wet snow, a record cold spell, hard-packed snow polished to ice by traffic, light snow over packed snow, sleet, deep slush, freezing fog, freezing rain and a freak warm spell that left the roads coated with ice with water on top. My driveway has a slight slope and when we had water on the ice I couldn't stand up on it without wearing ice creepers. However, the car made it up O.K.
During all those miles there were never any issues with traction or questions about being in control. I took the car to a snow-covered parking lot and finally was able to get the tires to break free, but even at their limit they behaved predictably.
I drove for eight winters on Blizzaks on my 2005 Subaru Outback and was entirely pleased with them, but I think that the latest version of this tire is a definite improvement over the older version.
