The general consensus, on this forum anyway, is that 19" E89 OEM wheels can crack and it's because of run flats in most people's opinion, which I think you know. It's also opinion that non run flats serve 2 purposes; To help prevent cracking and, and I can varify this, give a much better ride. I don't think you are without common sense and it's not rocket science to agree with the above based on common sense. You seem to have been round the houses wanting proof of this that and the other when there is none. So if you want 19's, don't deny yourself, fit them with non run flats, stop fretting about it, and enjoy your car. :thumbsup:
I'll cut to the chase, too, then.

How do RFTs crack wheels?

No, I was replying to john-e89's post. I don't have the 19" wheels that crack or RFTs.

Fair enough.

Returning to camber ... Let me state the obvious. The inner edge damage in your video is consistent on both rear wheels. This indicates a common cause - or causes - on both wheels, of course. As you know, the usual suspects in such wear are camber settings and tyre pressures, or a combination of them.

So, since you've reported similar wear on your previous/other BMWs, are the common factors the settings & pressures you use?
