Those cars come with “run flat” tires, which supposedly allow you to drive a few miles without damaging the wheel when the tire is flat. After which, instead of patching the tire, it must be discarded. Quite the advancement.

That was the case on some nicer cars when automakers stopped providing spares. But many cars today come with neither a spare nor run-flats. Many now are shipping with a normal tires, an inflator, sealant, and a roadside assistance telephone number.

Doesn’t seem like a bad trade off for not having to replace your rim, if the tire blows out and you’re unable to stop.

No they don't.
