Hi,
There's alot of posts regarding this.. some say don't do it some say doesn't matter as long as the tyres are BMW approved. then get a mobility kit..
Choice is yours to be honest and maybe speak to your specific dealer and see what they say...

With all this nonsense over the years I have just accepted and embraced the RFT technology. Yes, RFT's are pricey, but generally BMW Approved non-RFT's are not much cheaper in most cases, especially in the larger sizes. I have the space-saver (managed to buy a second hand one that was never used, so basically new) in the boot for extra piece of mind and so that if I do have a puncture I can save the RFT for repair, but it does take up space in the boot - at least if I need to I can it out. With non-RFT's that's just looking for trouble. Mobility kit is a must have anyway, since it is good to be able to repair and inflate a tyre on the side of the road if needed. Also a can of tyre sealer is good to have.
But back to the original question, and this is based on all that I have found out for myself with regards to RFT's and ditching them.
1.) You can ditch RFT's provided that the tyres you fit are BMW Approved (with the star symbol) - this is to keep motorplan happy
2.) Inform you insurance that you have ditched the RFT's so that they are aware of this, and get this in writing, since RFT's are considered a safety feature that you are now removing
3.) Punctured RFT's can be repaired provided that they have not been driven on for excess distance while under-inflated - also provided that the damage is not compromising the structural integrity of the tyre and as such very close to the side-wall
4.) Suspension set-ups are designed around the stiffer side-wall RFT's, so normal tyres will change the character of the cars handling
5.) Never mix RFT's with non-RFT's - known to cause very undesirable handling characteristics most of the time
6.) Keep the tyres properly inflated and regularly balanced
Not sure if I have left anything out, but the technology is improving and hopefully the prices will improve over time.
There is also a huge performance difference between the various brands - from my experience, Continental RFT's are hopelessly bad! Bridgestones RFT's are great though! Then Pirelli and Michelin RFT's are very good in the handling department, but known to wear fairly quickly in some cases. The latter are also usually more pricey and in particular the Michelin's are very difficult to find!
