Xdrive can give issues when you change the rolling radius so watch out for that if you change to another tyre, tyres that have the same sizes can have a different shape and width so they are not all equal just based on the raw sizing data.
Plenty of people ditch the run flats on x-drive with zero issues but you're not going to get BMW to recommend it.
It's a case of DYOR.

Had a call from my local dealer this afternoon saying they have RF tyres for my car : full set fitted for £1450 which is silly high. Pirelli Sottos 3 are £680 + £60 fitting therefore BM is charging double.
Thanks for your help and advice
