I'll expand..tire life is DIRECTLY related to alignment. Not just "they checked and the machines said its aligned- all green"...


There is a LARGE window within which BMW will say 'its aligned'... due to the CAMBER bmws use for handling they are VERY sensitive to toe. With a cambered tire any toe will dramatically accelerate wear....


Hence you need to take control of your alignment and TELL them where- withing the BMW specs- you want YOUR car aligned....


There is a long and broad history of BMW owners using these recommendations.
