I am going to be getting the Sumitomo HTR+'s, probably the next best thing to the Pilot Sport A/S, but half as much, only 100 bucks a tire. If you have the money get the Pilot Sports at 200 a tire, if not get the Sumitomo's at 100 a tire.
I have Dunlop SP Sport 5000's on the oem rims, same size as oem tires. They are only $97 each at Tirerack. They are very smooth, quiet tires with excellent grip, great in the rain... haven't had snow yet so can't say much about that.
