Looking at all these comments
Looking at all these comments, I guess I don't have much to add, but am in a venting mood. I have a 328d with pirellies. On Easter night on my long drive home was stranded for several hours thanks to these run flat pieces of garbage, because, obviously, there were very few tow trucks available. Why BMW can't figure out how to put a spare in a sedan is unconscionable. This four-hour, late night ordeal is a deal breaker for future BMWs for me. Fortunately I decided last minute to lease the car instead of buy it. It's a bummer, because, from the fenders up, I love the car.
