Been checking runflat availability for quite a while - the only scenario that works would be to purchase aftermarket 18 and 19 inch wheels and run the Z06 tire sizes.
A tire pressure monitoring system would be an effective preventative measure. Saved me once - had a tire going down, and the system flashed and buzzed to let me know. I was able to add some air and get it home safely. It would at least give you enough warning to deal with it, short of a blow-out.
You would still need the monitoring system with run-flats. If you're not aware the tire has gone down, it will be junk fairly quickly.
