This from Continental Tire: Contisense tires
These tires go beyond TPMS, they monitor pressure, temperature, tread depth, and also have puncture alerts.
Unlike the airless tires, I can actually see Slingshot owners adopting this - especially as we don't carry spares! This is scheduled to come to market in the next 3-5 years. My bet is that Continental is going to partner with a higher end auto manufacturer and offer them as a new safety system.
Even if you did add the tech to monitor all this, you'll need to be able to analyze the data - and you'll be locked into Continental tires for the life of your vehicle. Somehow, I don't see this as a mature technology.
