I just hit 17,000 miles and the noise from the Dunlop runflats are unbearable. Took car to dealer where i bought car, service rep acknowledge the fact that there is definitely tire wear on one side and that BMW is aware of the problem with these runflat. Rep suggest i purchase new tires or call Dunlop. Call BMWNA and mentioned bulletin, the response i got was that they have no knowledge of such a bulletin and if there was a bulletin it would only apply to MY2005. I have a 2006 E60 with sport package delivered 06/05. Called Dunlop and their customer service rep was nice and honest enough to say there is a bulletin pertaining to the irregular wear issue. The rep sent me to a Goodyear, (was told that Goodyear acquired Dunlop) tire place but they want documentation from BMW with spec for suspension, wheel alignment, etc. which BMW will not provide, waiting to hear from Dunlop.

The Goodyear tyres seem pretty good though for a runflat.
Hope this info is of some help to you.

Don't know what kind of BMW you drive exactly, but mine was equiped with M135 light alloy wheels and the GoodYear NCT5 runflats (245/40 R18 93Y). I can't say anything bad of these tyres, but on this forum i've read a lot of comments on the runflat tyres. It seems that non-runflats offer more comfort, but of course you need an extra spare tyre.

Buy non-runflat tires and you fell the difference
effect is more noise and more susceptile to tracks in the road (the ones trucks produce)
really a shame that the tyrepressureindicationsystem does not look at tyre pressure but at wheel relative speed. So you don't know you're driving with too soft tyres. As so much else has warnings, this would be a pretty obvious one to automate...

I have the same noise coming from the front wheels, I've changed the bearings because the dealer said so, no freaking change. Now I'll have to change all 4 wheels with non-rft...Hopefully this will fix the problem...

It depends on the size. I have the factory installed sport package 18" setup on the door it says: 36/front 42/rear .

And since I live in Sweden where we use bar as a measurement for tire pressure, that would be about 2,5/front and 2,9/rear?
