I have had a 2007 Nissan Maxima for the past 2 years. The first winter was mild and I had a few problems but nothing that gave me too much concern. I asked for the best all-season tires possible when I needed to get new tires and thought I'd be set. However, this past winter I was sliding all over the place when every other car on the road was fine. I went back to the shop and complained about the tires but they explained I needed snow tires - all season tires weren't going to help me. It's now winter again and I just cannot imagine spending around $800 for more tires (which is what they said it would cost - even tirerack.com has it for about $850). Is it a necessity to get winter tires for this car or was it just the bad winter and a car place trying to take advantage of me? Oh, I live in Pittsburgh and the weather here is pretty much horrible from now until March...
