On the BMW, the Pirelli are much better runflats. I had them on the F15 for 8 years. Switching to non-runflats will definitely improve the hard impacts you sometimes feel on the runflats. Non-runflats are quieter for longer tire life. Runflats have tendency to get loud after about 10-12k miles on them.
I would almost always switch them on my car. With that said, my wife drives the X5 mostly, so, it may be an issue with her if she gets a flat. So, I am debating whether to keep runflats on the X5 when time comes.
You will have to have fix-a-flats and portable air pump with you at all times if you were to switch to non-runflats.

That is what I did, switch to non run flats and keep a BMW fix a flat system. If you do use it, you will need to get a new tire just like you would with a run flat. You can repair a tire after you use the fix a flat. I had non run flats on my previous Cayenne and used a fix a flat once, it was fine…I drove it 20-30 miles with no problems.
