I bought these tire for the 2011/2012 winter season. The first winter I had them they were brilliant. Supurb grip in any snow condition. I plow parking lots but yto get to work ( where the plow truck is) is 22 miles. when I would travel to work I would pass 4x4 trucks as if they were standing still. I also never bougt a set of all seanon for the rest of the year. They feel a little soft in spring, summer, and fall. But they do the job. Noise: there is some but expected. just a slight hum nothing drastic. once again it is winter in chicago and the tire still have good tread, even though I drove druring warmer months. I took the malibu out during the first big snow and the tires still preform very well, not as good as new but pretty close. It is very difficult for me to get it to spin-out it just want to hug the road as if there was no snow.
