Does the X3 have runflats or not?

[xx3]

Ok I'm really confused guys...

I went to the tire shop (America's tire Co) and they swore that I didn't have runflats. (I have Pirelli Scorpions original tires from my 04 non sport X3).

Then I drive down to the dealer, and my SA says I do not have runflats, but I ask another SA in passing and he says all X3's do have runflats (as well as Z4's and the new E90).

I also remember the sales person telling me I had runflats, which is why the X3 comes with a doughnut spare instead of a full-size.

So today I've been doing some reading here, and on roadcrap forums and have found conflicting information. Do I have run-flats or not?

Before you ask, America's Tire Co was recommended by my dealer (and is just down the street from them), so apparently (according to my SA) they should know BMW's. They also recommended that I get some Michlin Sport tires or something like that. A quick look at the 06 X3's at the dealer confirmed that BMW has switched from Pirelli tires to Michlin tires for new X3's. What do guys think?
