Ditto on JCLs comments.

BMW allows huge amounts of 'toe' in their specs... like 0.08 per wheel, or 0.16 'combined' (ie the amount of pigeon toed-ness). Tires at that number will get 5000-8000 miles before they wear out (!!!). Set them for 0.01 or 0.02 and you will get 25-30,000 miles.

That simple.

And you cannot ask the dealer to "please check the alignment"... you need to get the details on what they are setting.

It is not camber- camber in spec is fine.
