In the US, that statement is true. And they all come with low-pressure
warning systems - 2007 and later use the in-tire monitors.

Agree, but in some markets, there is an alternative floor plan that
allows a spare in the E90/92:

One person posted early this year that he found the part number for
the E90 alternative boot / trunk
floor to store a space saver / emergency wheel, it is 51472146914.
There are also part numbers for the spare tire, jack and other related
stuff. Search realoem.com for more!


He actually ordered the item from BMW UK, BMW Germany declined it. I
think the alternative boot/trunk floor may be available in China or
Saudi Arabia or South Africa. Definitely not available in the US.

On the other hand, if you're in the US and want this alternate option,
perhaps one of the BMW independent shops who order directly from BMW
Germany might be able to source it. Contact someone like RD Garage,
Maxmillian Imports, Pelican Parts or even Dinan to name a few. Good
Luck!

While you're at it, replace those filthy dirty brake pads. 8)

It might be the Bridgesone run flats though. I've seen a lot of
negative reviews of those so have steered well clear. The Michelin run
flats (I have) don't appear to exhibit the problems you've had and
generally get the best reviews of the run flats. They are a little
more expensive than the Bridgestones though..and a LOT more expensive
than your Contis.
