I found the secret why BMW 19inch 326 wheels crack!

They all do that ! My last one did.

I'm going to get the geo set on the rear to 1/2 the standard setting for negative camber. I'll see if I can tell the difference in how it drives.

That's gonna be one hell of a hard ride!

Rims look good but I reckon tires will still be needed

It already was on 19s

On a new set of RFTs?

Doubtful the rims are suitable for RFTs :?

Strange thing to say?

I think the oe wheels are shaped to provide extra resistance to the runflat tyres slipping off the rim in the event of a puncture, obviously all other wheels won't have this feature.

Which is why I asked.

I doubt that the rims are any different to be honest, other than the BBS rim having move bead area and shoulder than the originals.

In addition given that there are photos on the web of failed RFT tyres that have only the sidewall in place.

Do you have any empirical information on this or is it just a hunch?

There is a difference between normal wheels & wheels designed for runflat tyres

As I mentioned, it's to keep the runflat tyre in place on the rim after it's deflated

Do you have 326's on your 5 series ?
I have on my last 2 F11's and haven't had any issues over 5 years with them.

Different sized tyres on 5s though :wink: far more sensible profiles

answering your question. The large Alloy wheel dealer in the UK also offers these wheels fitted with the RE050A RFT tyre as an option. I have now written to BBS to get a definitive statement from the regarding the use of their wheels and RFT tyres. Once i have this info, i will revert.
