Advise you look on the www to see how the gunge is pumped into the tyre.
It's an eye opener !
I would not like a flat tyre on a bank holiday monday in the lakes late at
night on the way home. The same applies to run flats as to tube of gunge.
Have a flat late at night and you will have a problem driving home if its a
long distance. Also run flats are not much cop if the side wall splits.At
least with a spare, even a space saver, which are no good for long distances
either or speed you can usually continue your journey.
