luis_m3 wrote No run flats, but if this makes you feel any better; when I picked up my vehicle at the BMW Welt, an employee tried to tell me that run flats were stock on the M3! I just looked at him, turned around, and walked away.
You're not the only one... don't worry.

I had the very same experience at the 2011 Toronto International Auto Show, the BMW rep. (he was a Manager) said the tires are RFT on the ///M3 that was on display at the show when I asked him what kind of tires on this car (I was to lazy to bend down

) he replied RFT ... I Just

and walked away.
I had (2) two Z4's with RFT (one was 2008 US build the last one was 2009 Germany build) ... never ever again it felt like driving the Fred Flindsone Mobile, you feel every little imperfection and bump in the road.
To the OP ... no worries the ///M3 does not have RFT (not yet anyway) If I was to order a new ///M3 then I would ask and make sure I get it in writing that the car I purchase has no RFT (
just to make sure that BMW does not change there mind during production and assembly of the car).
