Run-flat tires were installed. I had those on my last car and they are wonderful, also more expensive (hence, on the last car...) They are incredibly convenient and more safety oriented, especially for women worried about getting a flat tire on the side of the road in the middle of nowhere. With run-flats you can continue to ride and ride on the tires until your destination.
I'll have to look into the bulletproof glass option on my next car... :)
