BMW Run Flat tyres

Question from visitor, 06/06/2014 :I have been told instead of run flat tyres on my BMW I can have normal tyres and insert a gell incase of punctures - apparently gives a better ride
Answer by rezulteo, 06/06/2014 :

You'll get better ride, for sure. But you may also loose the run flat capability and the gel doesn't protect from a possible air loss. In this case you'll need a spare tyre.
