NO run-flats... as all have said... you get the do-nut spare... had to use mine yesterday.
Only 3 series with run-flats is the E90.
I find it unlikely that they "lied" to you...

(always funny how that's the first and immediate assumption)... much more likely that they were mistaken. It astonishes me how quickly new/old CA will just blurt out a "guess" regarding what they think the situation is... with out being sure or taking the time to find out. I'm not saying that it's ok... annoying more then anything... but that is most often the case.
By the way... great job by Roadside Assistance! The first guy sent to help me showed up within 30 min... but didn't know he was suppose to come inside to get me so he tried to call me, but my phone was at my desk... not on me. He left, I called a couple of hours later asking them where the hell they were... (which is when I found out they had already been by long ago...) she had some one at my car in 5 minutes... yeah, that's right... 5 minutes!!! :thumbup:
He was a perfect gentleman... had the tire changed in about 5 minutes... and I was on my way! :thumbup:
