After just doing a bunch of exhaustive research myself on this same subject- i finally settled on the BFG SuperSport A/S and couldn't be happier. Smooth, super quiet ride- and responsive as hell with spirited driving. I live in Florida, and the rainstorms here can be intense in the summertime. These tires cut through rainy and slick roads like no other tire I have ever owned..I tried a few days ago to get the tires to break loose a bit turning in really hard during a rain, and couldn't get the damn things to break loose! Just over 700 for the staggered set (225 rear, 215 front)
The tread design is VERY good looking on the car and even my wife complimented the look. The treadwear rating on the tire is 400, but it grips like it's a lot lower. VERY satisfied after 2500 miles- still quiet and smooth. Make sure you get an alignment RIGHT AFTER you get your new shoes. I chose Lexus dealer because they know EXACTLY what the car requires and solved my front-inside-balding-first problem common with this car. The tires and ride is so smooth it's seriously like hovering.

and the tire rack rating-

This rating was slightly lower than i personally would rate them, of course the 6.0 for snow traction skewed the average. Not a concern for me though since it only snows in Florida in disaster movies! :D
