Run Flat Tires on the Cayenne ?

[Jerry S]

I've got an older 911 so am unsure of these details on the newer models, but in my BMW X5, they com e spec'd with run flat tires and I find them to be controversial at best. They seem to be a love and hate for different reasons as this video shows.

Do any of the modern Porsche like the Cayenne have run flat tires as available or spec'd?
