I bought these tires last year, and naturally, here in the Chicago area, it didn't snow at all!
But this year Chicago and north central rural Illinois has been a real testing ground for this tire. Having an all wheel drive vehicle certainly helps quite a bit, but these tires add a level of confidence that I've never experienced in any vehicle before. Extremely good traction on wet surfaces, in bitter sub-zero temperatures, both light and medium snow, as well as the large mounds that leave many vehicles plowed in the parking space on Chicago's side streets. I was amazed at just how well this tread compound handles icy conditions too.
Very good performance at highway speeds... smooth and quiet ride. I don't know how long the tread will last, but I use these tires only during the ice and snow seasons, so I expect to get a few more years out of them. Very highly recommended!
