Hello everyone, as you can see this is my first post. We purchased a 2007 Impala LS last November with 29000 kms on it. We love the ride and handling of it on most surfaces. However, the first time we had it on ice and snowpack it seemed like the tires had been switched to skates. It scared the shit out of us. Thinking it may be the factory tires we put on brand new Michelin Harmony tires (which was recommended as a good all season tire for this car) to the tune of $900ish. Big mistake, still handles terrible. I also checked air pressure and all tires are set at 32 psi. The tire calls for a max of 44 psi. Is this just how the Impala handles on snow pack and ice or what? Please say it isn't so. HELP!
