I put these tires on to replace a mismatched set on my Mercedes. I had Bridgestone Protenza's on my car when I got it and got about 70,000 miles out of them and they were a great tire replaced 2 of them with Falken Fuzions and they were absolute junk. Discount prorated the tire and I got a full set of these tires. I have driven them in all kinds of weather conditions including some pretty bad snow last week during a blizzard where people were sliding all over these tires powered through on my car and only really had traction problems once and that was partially due to the depth of the snow. I am getting ready to buy a set for my wifes car solely on how well they did on my car in the snow. I didn't notice really any MPG improvement but I didn't see that as much more than a scam anyway. My only complaint is that these tires are soft in turns and make the car feel bigger than it is with the soft sidewalls. I usually run my pressure 45-50 psi on them and it seems to help. These tires do well at higher speeds also which kind of suprised me with the soft sidewall. Overall I am happy with this tire and will buy another set.
