Goodyear Eagle GT's

[Matt D.]

Personally (and i know kracka and mattd will disagree) I have used and LOVE BFGoodrich KDW2s. They perform and last better than any tire i have tried. I feel they are a good all around tire (and they are only about $120 a peice)
For being a summer-only tire their performance isn't that great for that price, I don't see the point of a 300 treadwear tire that isn't used all year round.

G-forces are bad ass, I've had them on a few cars. They are noisy as hell though, I will be looking for new summer tires soon, some that aren't quite so loud on the DD.

The Sumitomo HTR Z III's have a treadwear of 300. They're the best "Max Performance" tire you can buy; not as sticky as the Z1 Star Spec or Kumho XS, but I'll trade that for longer wear and better wet traction (not to mention much lower price) since they're on my daily-driver.
