I have been using Bridgestone
I have been using Bridgestone run-flats on two 3 series BMWs for just on 12 years now and I think they are fantastic. I currently have 225/35R19 88Y BS S001 RRFT on the front and 255/30R19 91Y BS S001 RRFT on the rear. I have never had a flat and the noise does not bother me. I drive on both sealed and non sealed roads and as my wife would say, tend to push the limits of the car a bit too much now and then. I find that most negative comments come from motor journalists/drivers who have still got their mind completely locked into must having a spare in the boot. I get around 70000 kms before replacing the tires. I carry two good tyre pressure gauges and always check the pressures every time I fill up with petrol. When you are spending $500/tyre you need to make sure you look after them. I suggest anyone thinking of buying them talks to the manufacturers (both car and tyres) before taking for granted comments written by someone who may have other priorities or pet hates.
Happy driving folks.
