Which model Porsche comes with RFTs? The Boxster has been equipped with a sealant/compressor kit for a number of years, but with conventional tires. Mazda does the same for the Miata, and many touring motorcyclists carry them as well.
And although it's been 10 years since BMW first introduced OEM RFTs (and longer for Corvettes, IIRC), other car makers don't seem to be jumping on the bandwagon. Perhaps if future RFTs are designed with greater ride improvements and (more importantly) lower costs...
