I love these tires...they're everything I hoped for based on the reviews I read here. They grip well in all conditions and I don't need to slow down dramatically in the rain like I did with all my previous tires. When I first got them, I thought my car had lost power because I wasn't able to make the tires squeal easily anymore...then I realized my new tires just stuck like glue (all my old tires spun like crazy even when new). I haven't driven them in winter conditions, and I'm tempted to give these a shot for those...but, I have a set of Blizzaks at home that should have one more season in them, so that probably doesn't make much sense.
I have some concerns about how long these tires will last, but I'm really enjoying them a lot right now. Highly recommended.
