I'm not sure where you live but if you're not having any issues with the Pirelli's and you're not in the mood to spend 1500 bucks right now to grab some Michelins I say stick with them.
Run-flats have come a long way since 7 or 8 years ago , especially depending on the manufacturer.
I literally cannot use those Goodyear run flats where I live. And, you do make a good point about what cost does this convience come at? Suspension parts on these cars ain't cheap. I remember horror stories from guys back in 2006 who literally had strut towers getting blown up because of those OEM run-flats. It's great if you can drive around on a flat tire: not so great if your stut towers have shot through your hood.
Another problem was with these delicate active headlight rigs. Remember all the sad eyes?
