Just got a 2006 SL55 AMG. I was wondering what I should do about tires. I live in Chicago, so the weather is not great. I don't really plan on driving in lots of snow, but I am also not really concerned with high performance. The car is not modded and I don't race, drag or do time trials. The car will be driven for basic city and highway duty. I am wondering if I should switch to all season tires or something else that may be more appropriate than a high performance tire.

Thinking Pilot Sport A/S - from what I read, it should pack plenty of performance and also give me longer wear.

I had those on my car - lots of snow in Seattle this winter, those all seasons were practically useless. Better to get a dedicated set of winter tires if you want to drive in anything more than light snow (> 2") otherwise, be prepared to toggle cold/winter mode and tap lightly. Forget about any slope or hills.
