The one condition you want to avoid is thin tread on the rear.  The spare
would have been better used at the rear.  This can be serious if the rear
tires are very thin.

With stock suspension, BMW front tires wear on the outside and rear tires
wear on the inside.  If you wait a long time to rotate, so the wear pattern
is set, rotating effectively changes adds positive camber to the front and
negative camber to the rear, exactly the wrong direction.  This is why BMW
recommends against tire rotation.  Rotation is OK if you do it frequently.
