I had Michelin Pilot Sport All Seasons on and they were great, I just got Yokohama Advans installed today... 245/35R18s and 295/30R19s.

I'm kinda bummed, because it looks like I could have fit 255/35R18s and 305/30R19s on there. Oh well ...

I'll have to drive them for a bit to give a proper review... look for the thread with pictures of the new tires soon. (Need to wash the car).
