I purchased my '08 SES last summer, and I LOVE this little car. However, we got our first blast of winter last week, and my Focus handles awful on slick surfaces. The only way I can describe it is that it's squirrely as he**. It feels like the rear end is gonna swing out any second. It has Perelli P6 tires from the factory. Anybody else have this problem? I will install special winter tires if this will cure the problem, but I'd like some input from others first. I DO NOT want to part with this gem, but since winter around here is L O N G , I can't live with the car the way it is. H E L P !!
