Tires
I'm running the Pirellis and am quite disappointed in how little "sport" I get from my so-called "sport sedan." I'm quite looking forward next winter to trying a sportier A/S without sacrificing a quiet ride and hopefully a solid tread wear rating. Sure it's a tough ask, but I'm happy to lean on the tirerack.com site. Like most of you, I'm homing in on the Conty ProContact, Conty DWS and Michelin Pilot A/S 3.

If I can get a good deal on OEM wheels, I'd jump on a set of snows and set of summers. Fingers crossed! A/S aren't great at anything in their pursuit to be a "do everything" tire. Unfortunately, it seems wheels in good shape cost a mint and those that are inexpensive seem to have been used by blind folks that park using braille - loads of ugly scratches. I continue to dream...
