Good question. Now as far are tires go, the Nissan GTR also uses Bridgestone RFTs as OEM, so do Ferrari etc. BMW - like these manufacturers - have developed a OEM tire with Bridgestone to suit their cars, so this makes me believe the issue is with the alloy. After reading people's experiences with cracked rims on BMWs in general it appears that more often than not it only occurs with certain styles of 19 inch rim. There are several reports I have read of cracked rims even with non-RFT tires.

I checked an old chrome rim I saved from years back and it actually has a similar crack in the same spot as Rolfs. It was done by going over a 4 inch Kerb at around 40km/h. Tires at the time were non-runflat Falken FK451 205/40/17 I think.
