This past weekend I bought a set of 16 inch snow tires for my 325i. The tires have enough tread to last a few winters, and the wheels are just the stock wheels that you see on lots of e46's. They look very boring compared to my sport wheels. Sorry I don't have a photo of them, since I have no digital camera (but am looking into one), but I found these pics on google, and tirerack. By the way, I bought the wheels on Craigslist.

Sorry for the bad picture
