Just got my car with these tyres and wondered how they'd work if they went (I was told they are prone to punctures and are expensive) and how easy it would be to tell (the handoverperson's "the light just comes on and you have to press this button to equalise things" was less than convincing!).
Be interested in your experiences of how it happened and how good Mini Emergency were. Didn't expect they'd come out for a puncture in a run flat tyre so that's pretty good.
