The other day I hit a pretty massive pothole on I-93 just north of Boston and there was a loud bang. Today I was taking a look at my wheels and I noticed that my passenger's side front tire has another one of those dangerous-looking bumps that I seem to get a lot. I know I've got to get a new tire..
My first question is: I need to get a set of 4 new tires, correct? My 330 is an xi, with all wheel drive.

So assuming I need to get four new tires, what are my best options? I have 225/40ZR18 Michelin Pilot Sports on there right now and I like them. What is another good performance tire I should look at?
