The run-flat v normal tyre debate mainly concerns road noise, ride comfort, convenience and price issues. With my previous four cars (all BMW's) two had run-flats and two had normal tyres, and having had the misfortune to have had punctures with both types my views are as follows:
Road noise is more to do with with the road surface than the type of tyre. Run-flats may be a little noisier but the difference is negligible when compared with the noise levels from different road surfaces.
My last SUV had normal tyres with sports suspension, and when I first took my wife for a drive in my Lexus UX with run-flat tyres the first thing she commented on was how much smoother the ride was.
Regarding convenience, I prefer not to carry tools or a spare wheel as they take up a lot of otherwise usable space, and having experienced punctures with both types of tyre and suffered the inconvenience of using the compressor and goo remedy on a cold wet winter's night, I think this is a no-brainer in favour of run-flats.
Although run-flats are more expensive and usually require a new tyre in the event of a puncture, I think the benefits far out weigh the disadvantages.
