Beyond the issue with unsprung weight, that seems like a truly awful trade-off. A run-flat still needs to be serviced if punctured and is still vulnerable to sidewall damage and potential blow-outs. If you carry a full size spare (I sure do) in the event of most tire failures, you still have the ability to get much further down the road with less drama.

- rpcope1 11y agoThey don't come with one stock, sure, but there's nothing to stop you from going and buying the correct sized steel (or cheapo alloy) wheel and a decent tire that's the same size as the ones on the car and carrying it with you (and throwing the junky temporary spare out). Yeah it requires you to work a touch extra on the setup, but it is worth it. The extra full size spare will cost about the same as going with run flats vs non-run flats each time you swap out tires. If you're interested, it's pretty easy to get the correct sized wheel from somewhere like RockAuto or Discount Tire Direct.
