I replaced my runflats with GY GS-D3's, non-runflats. I carry a small compressor and a plug kit for those times that AAA is not an option. On long trips I also carry a can of fix-a-flat, it will ruin the sensor but I would rather ruin that than be stuck in some remote area for a long time.
I also have a Corvette and I am running non-runflats on it also (Michelin PS2's). Of all the years I have been driving I have never had to put a spare on. I have picked up several screws through the years and have always been able to drive to a tire store to get it fixed, sometimes days after I noticed the screw.
Do what ever makes you feel comfortable.
