I put them on my Subaru last October and overall they've been great. When I first put them on it felt like it took more gas to get the car moving versus the old tires, and my gas mileage has dropped since I've put them on. However, I've since gotten used to them, and most people haven't noticed that after getting them installed on their vehicles.
As for performance, they've done very well in everything I've driven them in. On smooth asphalt they're very smooth and quiet, though on concrete with horizontal grooves they get this high pitched whine where you can listen to the pitch of it rise and fall with your driving speed as you accelerate or slow down. They've been great in the rain, and we didn't get much snow this year but I did drive it in some ice, about 4 inches of wet snow/slush, and about 8-9 inches or regular snow, and they performed significantly better than the original tires did.
I keep saying I'm going to write a review of them now that I've put some miles on them and have driven them through different weather conditions, but the thought never occurs to me when I have the time to sit down and write it out. Overall though I'd recommend them to anyone who's looking for a very good all around tire.
