Not BMW, but I'm sure the same applies. The mother changed her car recently, said I would give the alloys a proper (wheel off) clean. Glad she hasn't had a puncture so far as I snapped the head of one of the lugs off with a breaker bar trying (failing) to open it.
All others seem to be the same, trigger happy air powered wrench monkey I presume.
Question: will a decent air impact wrench loosen them? Don't want to be left having to drill out 20 threads.
