What a pain....

They will check the wheel on the tire mounting machine they have. Apparently the machine has a instrument (similar to a Dial Indicator) that will measure Total Indicator Runout (TIR). Apparently the BMW tolerance for a alloy wheel to be out off roundness (as measured by the instrument [dial indicator like tool]) is 3.2 mm or 1/8"
If it exceeds this they will tell you the wheel is bend! They will further tell you that you went thru Pot Holes. If there is no evidence to the fact that you did go thru a major pothole then you should argue that point with them.
If your dealer is a good one then they will change your wheel having a hairline crack without any questions.
Let us know how you make out.
Good Luck

PS. Also note that other members have had there wheels changed without any issues when they had hairline cracks. Search this forum for more posts on "296 wheel cracks" also note that some members reported they got a improved design wheel ... you can find the posts if you search. Finally should the dealer tell you you gone thru a pot hole ask him on what he bases this conclusion and for him to show you the evidence i.e damage on your wheel, also ask them whey the front wheel is not cracked only the rear? I hope you don't have any issues with your dealer.
