I've never driven on them, but they seem to get a lot of hate. Are they loud, mushy, expensive, ...?
Just curious what's so bad about them, especially as more and more new cars are coming without spare tires.

Expensive, ride like shit, don't last too long, not as good handling.
Fun fact: More than half of the run-flat market is BMW.
The Bridgestone DriveGuard tire looks interesting; it's a run flat specifically designed for cars that didn't come with them from the factory.

Run-flats should be used on appliance commuter cars, and nothing else. They're heavy so more rotational mass/worse performance and efficiency, they have stiff sidewalls so they ride like shit, and they don't grip as well as their non-run-flat counterparts.
They're a novel idea, but I sure as hell don't want them.

My father had runflats on his BMWs all season and winter tires, and they truly suck. He bubbled a tire from a pothole on his old tires and got non runflat as a replacement, the tire also dented a rim slightly.

Expensive, disposable, and you'll never find one when you get that flat on a Sunday in rural South Carolina.
I never thought anything would make me appreciate the temporary spare.

Poor ride quality due to stiff sidewalls, reduced grip poor treadwear plus having worked at a large chain tire store they are a massive pain to change, especially getting down into the 40-35 series sizes.

There's a compromise going on, because they have to have stiffer sidewalls (or something else in place of that) in order to be OK to drive on without air inside. That obviously affects weight and handling.
I'm unsure how much of the dislike is more to do with previous generations of runflats, because they've definitely come on a long way over the last few years. I haven't driven on any modern runflats so I can't say.

Based on my experience with an '09 RX-8 that came with factory Dunlop run-flats, the ride was unnecessarily harsh and skiddish. I replaced them with Goodyear Eagle F1s after 5k miles and the ride quality immediately changed. The RX-8 stock suspension is rather firm but the tires made it more pronounced than I wanted. It depends on your preference, but in my case it felt wrong. For me, road feel is more important than the peace-of-mind that comes from being able to drive on a "flat" tire.

Also to add to whats already been said. Some of them, if you get a puncture, theyre no supposed to be fixed. So you have buy a new tire if you pick up a nail or whatever.
Theyre not all bad and have certainly come a long way since first introduced. But youll pay bif money for the nicer ones. Just dont expect them to perform or ride like a non runflat performance or touring tire.

harsh ride, easy to damage, impossible to repair, expensive. No redeeming qualities really
