Rocky05, Very Good Point!
The RFID tag in a tire is there for the sole purpose of inventory control and accounting. It is most useful to the manufacturer and distributor or seller up to the point that the tire goes on the car. As far as I can tell it provides absolutely NO BENEFIT to the purchaser or user of those tires. Except perhaps, in the very rare event of a tire recall. Again, it benefits the seller who has to deal with the exchange, account for and dispose of the old tire.
On the other hand, the Tire IQ device is a run-time sensor that provides valuable sensory feedback data while the tire is in operation. IMO that makes it a piece of safety equipment.
Monitoring tire pressure and temperature has been around for at least 20 years. It has been standard equipment on very high-end exotics for the last 5 years at least. And they are usually part of the wheel assembly and NOT the tire, as they have to integrate with the car electronics.
These two devices have very different purposes and uses. Why are they being combined on this forum? Only one should be the topic here.
With the strong possibility of another 250+ million new drivers in China and India, all buying their first car in the next 5 years, and with each car having at least 4 tires, I would think that RFID tags in tires will be an expanding market. That's an understatement! Just my opinion...
Good Luck.
