Thanks Peter.
Though I have to say, I have run BMWs for many years, all on runflats and have never had a problem with them. I especially like the fact that when I got a puncture on a motorway, I was not left stranded on the hard shoulder waiting for the AA and risking life and limb, let alone the car itself, to the antics of myopic drivers who can't tell the difference between the inside lane and the hard shoulder, to say nothing of the difference between a stopped car with hazards flashing and a moving one!
I do take your point about suspension as I know that BMW set their suspension up around the stiffness of run flat tyres.
I suppose I could always take the pressure sensors out if I were to use a pre puncture sealant as it will prevent any air loss either from a puncture or porosity of the tyre so they would become redundant.
John.
