My Ride: E61 530d Touring, May 2004
A huge amount of chat about tyre types on this site.
Just wondered what the actual usage is - is there a silent majority using the run flats that are mostly supplied as standard

I do not know a country where the roads would be so smooth that RF tyres would run nicely.
On the other hand, if the roads are so bad that you get a puncture every year, the RF's is a must.
Voted "have RF's" but I will get rid of those as soon as the thread is under 3 mm.
At this point it seems that the new tyres will be non RF GoodYear F1's.

My Ride: 535d Sport Tourer - E34 M5 Race Car
I had a r/f puncture at about 110 mph (no great drama, just a bang) on Tuesday night. Happened at 6:01pm 219 miles from home so rang local dealer but they'd gone home. Rang BMW Assist who sent a low loader to take me home. Next morning, neither dealer nor any other tyre outfit had a runflat in stock - all 2 day lead time and nearly ?200 each. Rather than pay ?400 for one axle, I swapped all four for Kumho Ecsta SPT's (I've raced on Kumho's so am happy with their characteristics). Ride, grip, road noise (lack of ) is transformed. The punctured tyre would no way have lasted 100 miles @ 50 mph. I drove 8 miles @ 40 mph on it and the sidewall had parted completely from the tread (gaping hole) along 1/3 of the radius of the tyre.

I am one who plans to switch to conventional tires this autumn.
However, I recently had a thought
(strange eh what - 
)
Do Run-Flats offer better protection again rim damange from potholes with slim (40 section) tires?

a) car is quieter than my old E39 535iA (with M-Sport suspension on non-RFT 235/45F 255/40R 17" ) - by quite a bit, and including tyre roar!
b) it's tramlining quite a bit. Not unexpected as such, but the extent of tramlining was a bit upsetting.
Checking the pressure - the rear tyres were at 2.0 bar (sticker says 2.7 - 3.2), and fronts at 2.1 (nearly right). After fixing that, tramlining disappeared and car is even quieter. Ride also seems to have improved - or perhaps I'm just getting used to it.
Having done less than 1500 miles yet, I'll stick with the RFT for a while, then we'll see! Ultimately, it's going to come down to replacement costs - the original buyer of the car specified it with the space saver spare, so I may well go to conventional tyres if the differential is strong enough, but the RFT performance per se is perfectly adequate for my needs and driving skills.

My Ride: e39 525i Touring, will order e61 as soon as I can decide on engine and options...
I have the 245/40/18 GoodYear RFT + M-Sport chassie on my car and both noise and comfort are better (by quite a bit) compared to my previous e39 525i with 225/55/16 Conti Premium Contacts and standard chassi. I guess that 1. M-Sport is a really good compromise, feels more composed than e61 standard imho 2. RFT technology is rapidly evolving.

I have replaced the Runflats with Pirelli P-Zero Rosso standard tyres and I have found:
a) Noise levels have improved a lot, especially on coarse surfaces.
b) Tramlining (which never improved no-matter what I did) has vanished.
c) Ride has improved, especially over sharp ridges.
d) Handling has changed. It seems a bit more prone to oversteer, but I am still playing with the tyre pressures.
e) What did turn into a major concern with the runflats though is the fact that the availability is not always good and you could wait a few days for a replacement. When they are punctured they cannot be repaired and have to be junked, so you ALWAYS have to get a new tyre. This makes the availability problem even more important.
