How do run flat tires work?

It’s a type of tire that has no tread at all, instead relying on the rubber of the tire itself to grip the road, which makes them easier to repair than a normal tire. But since you can’t actually drive the car with a flat tire, the driver must use the spare tire instead, which means driving a short distance without that tire.

Incorrect. Run flat tire has a rigid rubber inner tire that allow cars to continue to drive for a certain distance at reduced speed after a leak or rupture.

Can you elaborate on the “leak or rupture” part, and how the car could keep driving after it?  How exactly does this work?  Do I get to be the detective in this story, and figure out how this is possible?

I just did. I'm not going to explain it again. Goodbye.
