I'm just curious, what is everyone doing about a spare if you change to non RF's? I've had a puncture in my RF's and was thankful I could still drive for a couple of days...and not be stranded in the middle of nowhere...even with BMW Assist.

Also, if I had to get a RFT fixed, my car would still be on the road ...

The rims are different. I saw a program on the TV and the rim has a band running around the centre of the inside of the rim which supports the centre of the tyre should it have a puncture. This is made of the same material as the wheel.
So instead of this? ? U? a runflat wheel has this? UU if you get my drift.

I've done it for a few km's and I found it horrible. It sounds like your rim is getting raped by the tire and there is absolutely no handling to mention anymore.
I ordered GY F1 now and a spare.

The rims for the BMW runflats are standard rims. (If they were different there would be a marking cast in the metal indicating that runflats only are allowed.)
The tire noise will be greatly reduced by rotating the tires left to right. The noise is due to angled wear or ramping of the large tread blocks. This is normal wear pattern and gets evened out by rotation.
I switched to Pirelli Zero-Nero M+S on my 545 and they are much quieter and less jarring than the Dunlop runflats. Way better mileage too.

BMW use the tyre-only technology where stiff sidewalls take the load - the hub is standard.
