I've used two other brands of snow tires before buying these, General (Articmax) and Bridgestone (Blizzak).
First impression is that in the dry weather, these ride more like an all season tire. The Generals and Bridgestones were very loud and kind of felt squirmy at highway speeds. Once you got used to is, it was fine. The Dunlops are smooth, quiet and responsive at all speeds.
On to the Snow, these are about 80% of the other two in the snow. They are still good, but not as sure footed, especially in heavy slush conditions. With the other two, I felt like my Mazda was an SUV!! I don't have the same confidence with these, but if you drive "normally" they will get you were you need go without much drama.
Overall, I think they are a good tire, but just not up to the level of the other 2 I have used. I cannot comment on tire wear, as this is the first season.
