I just got the Yokohama Advan S4's. Just about 500 miles mostly dry with a little bit of rain. So far they are very good. My old Michelin PS2 were great too, but I need a snow tire as well. Check out Tire Racks reviews on tires. They rate the Advans real high.

10/19/07. Now it's over 1000 miles in rain and dry conditions, and after having the exhilaration of taking an exit ramp a wee bit too fast. These tires are just fine. I see no difference in handling between them and the Michelin's (Which is pretty great). The real test will be what I say after winter. By the way, when you consider the cost, Consumer Reports' ratings aren't too swift. But they don't seem to like much of anything so I don't take them seriously.
