I bought the tires from another person with 2 seasons on them and about 1/2 tread left. I drive pretty aggressively in a car that is RWD, heavy, and 370hp. This tire is extremely impressive. It performs better on extremely slick roads then my summer tires do in the rain. This winter we've had multiple days where it was icy and some pretty heavy snow falls. I never once felt like I was going to lose it. Once traction control kicked in, the tire gripped instantly and I was in complete control. I've even pushed the car pretty hard around long sweeping corners in the snow and it barely slid. I took the car out on a day where we got 3-4 of snow on unplowed roads to see how it would handle and I was able to safely get up hills, stop, and turn. I feel safer with these tires in this car then I did in an AWD envoy denali.
I only have a couple complaints. Due to the higher sidewall and softer tire, there is a decent amount of roll when going around corners. There is also a noticeable amount of tire noise especially when slowing down. Not enough to prevent me from buying the tire again though.
Overall I am very satisfied and plan to stick with blizzaks in the future. I'm looking forward to seeing how the tires are when new.
