Had these installed January 09. I live in snowy Wisconsin. These have the worst traction of any tires I have ever owned. It's now end of October 09 and they are starting to slip even when it rains. Bad choice on my part. Live and learn. Definately going back to the Uniroyal Tiger Paws which I had previously. The difference was night and day. Sears service and technicians were good. Tires just are no good.
