I have Toyo Extensas on mine. I got them last year at a Tire World in Rochester, NY. I believe they cost about $400-450. I chose them mainly because they had them available same day (I'm not from Rochester

I've put about 25000km on them so far, seem to be holding up fairly well. My car is primarily a daily driver, but they also handled fairly well when I went to Watkins Glen earlier this year.
Just to add: Just like any "All seasons", they are really *three* season tires. They don't handle ice well at all. My other car was having some work done, and I drove the Fiero one morning when the temperature dipped below freezing overnight. Scary. Cobalt's Michelen Defenders are not much better on ice either, though. Nothing replaces a decent set of winter tires.
