Run flats - How harsh are they really?

Ive had a 320d se this week with dunlop runflats on it and I didn't find it ran any better than my 530d msport with Sportcontact 3 SSRs on and if anything they ride a little worse than the Goodyear NCT5 runflats that were OEM.

One thing probably worth mentioning since I've seen it on others sites when researching runflats is don't forget to tell your insurance company you've changed to non run flats. You probably are know this already, though nothing lost mentioning it, since insurance companies will use any excuse to get out of paying out obviously.

Does this make a big difference in cost ?

From what I can gather it shouldn't make any difference to your premium as changing to non run flats does not increase the performance of the car so there should be nothing to lose by telling them. But of you don't tell them then you are giving the insurance company a possible get out clause on an £Xk car.
 
Do you have to do anything special when changing to non-RFTs?

Does the pressure sensor need to be turned off or anything?

Will be switching to non-RFTs when this set go on the E60 (M sport with 18" Alloys).
 
I have Michelin PS2 ZP on my 335d and will be buying them again when they wear out. The ride is firm but is not uncomfortable and the car handles and rides very well on them. Not sure about other brands or generations but the PS2 ZPs are very very good, they are a little noisey until warm when its very cold but other than that I've been very impressed.

It rides better than the stupidly hard Civic Type R I had...

In the boot is a BMW M Mobility Pack, which is what the M cars without runflats or spares get - it's basically a pump and a can of sealant. It was £130 from BMW.

Anyone have any photo's of this BMW mobility pack ??
 
Never mind the fact that normal tyres offer a better ride, runflats are extortionately expensive. £240 a corner for the Z4! I got a full set of FK452s for ~£360 in August.

I changed the RFT's on the Z4 to regular tyres and it transformed the ride and handling of the car. Massively better. In the boot is a BMW M Mobility Pack, which is what the M cars without runflats or spares get - it's basically a pump and a can of sealant. It was £130 from BMW.

Or, y'know, get a sealant and pump for inside £50 from Halfords. Admittedly it won't have a BMW logo on it.

Saabs used to come with lovely white cotton gloves back in the day. Not really the most practical colour for changing wheels but a nice touch nonetheless :p

Without wanting to be too pedantic, I'm not sure that's the ///M Mobility kit, I think it's the "normal" BMW mobility kit.

They may have changed it for the latest M3 but the ///M Mobility kit from the E46 M3 looked like this:

Having used mine a couple of times they do work well as a "get home" option, unless you buckle your wheel then you're stuffed!
