My Ride: 525, Dec 2003, Silver Grey, Black Dakota Leather, Bluetooth, Satnav, 18'' Runflats, Sunroof, Folding mirrors, Automatic
My runflats are not too noisy, but they wear at an incredible rate, will soon need replacing after 10,000 fairly sedate miles. They wear far more quickly than any tyre's on any car I have owned before. Combined with the rubbish fuel consumption ( nowhere near official figures ), this thing eats cash.
Also, what happens if you get a puncture a long way from home?, I had a puncture a couple of weeks ago, had to wait 2 days for a new tyre to be ordered & fitted. It didnt matter then, but what if I was away somewhere?.

I have hit 30,000 miles on my Bridgestones and the rears just need replacing now.
My combined mpg is steady at 35.7 and the official figure is 36.2

525I Se, average low 20s on cross country commute.
Tyres are Dunlop SP Sport 01, 245/40/R18, Just had one replaced , found a good place ?70 cheaper than BMW dealer, near where I work ,( ?155 , BMW wanted ?225 for same tyre ).
The tyre fitter checked the other tyres, all wearing more on inside edge than the rest of the tyre, front & rear. Not too bad now but he said they only had a couple of thousand miles left, they seem to be wearing faster now than when new, maybe a softer compound when they wear down a bit..
Like you, I always got 25000+ miles before, from all cars including BMWs. I can only put this down to the tyre type.

I've recently purchased a 525 running on 17 inch Bridgestone run flats. The car had done 18k miles and the rears were almost down to the tread wear indicators so the dealer put new ones on before I took it off their hands. I reckon the fronts have about another 5 - 8k miles left on them and will be happy if I can see 24k on the clock before changing them. I'll be watching the pressure in rears carefully to maximise the life. (Don't want bald centres with loads left on the edges, which I usually find happens if you run them at exactly the manufacturers recommended pressures - I normally go for a couple of psi lower on the rear and a couple over on the fronts as the majority of the time it's just me in the car).
As for fuel economy, it seems to be averaging about 29mpg's which is about the same as I used to get on my old E39 523. I did read in the owners manual that using less than 98 RON fuel could detrimentally affect the consumption figures, and I always use the cheaper superstore 95 RON fuel. Maybe worth filling up with Super unleaded next time and see if the extra pence per lite pays off?

Interesting quote from the latest edition of the BMW Magazine (UK edition, page 89):
".....The extra-stiff sidewalls on BMW's Run-flat tyres also enhance the car's driving dynamics. During a recent test session at the legendary Nurburgring Nordschleife circuit, a BMW 530d fitted with Run-flat tyres lapped the track 10 seconds faster than a 5 series fitted with conventional tyres. BMW's run-flat technology also aids braking performance."

I don't think the Nurburgring drive reflects most peoples day-to-day road experiences? (I know BMW drivers has a bad name, but...)

M5 + Runflats = No suspension at all.
