--Edit-- Just re-read the post. Tirerack.com seems to have the best prices and best designed website.

I just put new tires on my car, and did a lot of research. it seems (at least for me) that the Bridgestone Potenza 009s are the best tires, for me anyway. From what I've read the two most common complaints about them are that they're noisy (and they are) and that they don't grip well, but from what I've read it's mainly people with sports cars complaining about that.

Supposedly though, they rate very well in dry, wet, and snow. I can't vouch for the snow (yet), but I've found myself braking hard in both the rain and dry and they stick very well. They also hold remarkably well under hard acceleration and cornering.
