No. I was making a point that I think that the reason our cars come with negative camber(specially on the rear) has to do with improvement of handling. Regardless of tire wear.
One should, on the other hand, get an alignment if the handling of the car requires so. The decision to take it to an Indy, Just Tires, or to your local BMW shop is yours. Me personally, would rather have somebody at a BMW center work on my car. But that's just me.
