All tires are run flat. If you don't believe me just take a gander at any number of those cop shows and you will see any number of nincompoops zipping merrily about with flats. The only real question is what does it cost to run flat. With some tires you pay before and with others you pay after.

I just wanted to make the point that if you ever find yourself in the situation where you have to run flat with these tires, it is going to cost you the tire in something under a 1/4 mile. My rim survived but I don't think I'd guarantee that in all cases.
