My warm season tire is the BS RE970AS PP, an ultra high performance A/S, and I love it. Compared to that, this tire clearly provides better snow and ice traction. I drove on I495N between Delaware and Philly during a recent light snowstorm. The temperatures hadnt risen above 20F for five days and the salt/sand trucks hadn't been out yet, so the left and right lanes were virtually virgin with two inches of unmelted powder. Just as I broke single file formation into the left lane, a jacked up F150 broke to the right lane. Within seconds he nearly fishtailed and fell back in line. I was worried, but kept plowing ahead carefully, and before I knew it, I was the only one in sight, pushing 80mph after having passed the most daring of other drivers going no faster than 55, so I took the opportunity to try braking and swerving ever so carefully to test the traction. The combination of AWD and these tires resulted in an astounding amount of traction and confidence. Within the limits of my nerve, I literally could not break the rear end loose, or even get the traction control to kick in-- I finally gave up trying. In the grocery store parking lot, jackrabbit starts from a dead stop into a 90 degree parking spot did break the rear end loose, but barely, and the car fell in line immediately when traction control lit up. These tires clearly suffer more squirminess at near triple digit highway speeds, and they aren't as glued and fun in dry weather as the RE970s, but they're definitely no worse than the Michelin Pilot Exaltos or any other all season grand touring tire--may even be better than many. Bottom line, I thought about switching these in/out every time the weather forecast warranted, so as to keep the 970s on as much as possible, but these winter tires sacrifice relatively little dry traction and provide so much more confidence in the snow and ice, that from now on, I'll be putting them on come November and I'll leave them on till the spring.
