I just didn't think that Costco would screw the wheels up.
Another here reports, a "tire change shop" broke his lugs on hubs ... yikes.
Truth short of taking you car to a very expensive "high end" shop you just can't know. I got it ....take it to BMW service they can install the tires .... just pay double!

So what I now know is take pictures and talk to the management about your fears. If they seem to not understand then do not give it to them!
Truth it the labor that gets little often just doesn't care about their handling of you expensive machine. Even worse perhaps they want to hurt you machine?
