You are welcome, this is after all what this board is all about.

I am leaving for a business trip this week so it will sit until I can get it in to BMW. I do have the tire and wheel insurance but trust me our roads are fairly good and I pretty much drive like a grandma! I am glad I will go to the dealer armed with the knowledge I have of this issue from this board! Heeee, hubby wanted to drive my car while I am gone......too bad not going to happen. I actually want to be the one to take my car in because I have all the amo from this board. Pitiful BMW, I have only about 9,500 miles on the car now!
I fear you have a hairline crack (slow leak) and there should be no issue to replace your wheel. The fact that you are well informed from others here on this issue and that BMW now apparently has a stronger design of the 296 wheel should help you out well.

Make sure you ask them while in the garage to check the left hand rear wheel as well.

In addition to what I wrote to silverstone above keep in mind that your rear wheels are set up with a negative 2.5 degree camber (you may have seen posts regarding this). Some members have had this negative camber reduced by 1 to 1.5 degree to reduce the load to the inner edge of your wheel. The negative 2.5 degree is really not that noticeable if reduced by 1 degree or so. I am convinced that this negative camber along with the RFT caused both my rear wheels to crack.

The wheel that BMW screwed me on and never paid me for now has a place in my garage and garden hose duty so to speak (photo in my Retired car garage here ---> Click to Open at least I can have some use out of it)

Good luck to you and let us know how you make out.

Cheers, Rolf
