  Not for cars, though. There is probably a market for tire monitoring in mining equipment, which is probably not constructed with the same built-in systems that consumer cars have.

    You are incorrect. Most modern cars have TPMS to tell you when a tire is losing air. There are two ways to do it. Either you use the same signals ABS uses to tell how fast each wheel is spinning and look at the tire which spins at a different speed. The other way is to have actual pressure sensors inline with the valves that wirelessly communicate with a system in the car. This method has the upside of allowing you to see constant tire pressure values on all four tires at all times. The downside is that it is more expensive, it's something that must be managed when you get tires or wheels changed, the batteries run out, you often have to pair each wheel-sensor to the car separately so that it knows which sensor is which wheel... This is an example system: https://www.ebay.com/itm/402816216014?epid=21038233158&_trkparms=ispr%3D1&hash=item5dc9b7abce:g:pq0AAOSwmR1gi6qr&amdata=enc%3AAQAGAAACkPYe5NmHp%252B2JMhMi7yxGiTJkPrKr5t53CooMSQt2orsS%252BMKizvpuEDUfX4dvRWfUzY2vJJmZPPOhoQ3V3J7BTwRTk6T36hny0RMjypNd4LkVs3QVasO%252BTIWDY85DMvkcbrhenQVa44dMEqmSBZM2%252BGlM%252BYxj9OWg0tX%252BhyWszR4%252FhR6%252F%252FUWEP3V9lOg7q9yxKKMt6MsyhIJms70I5FS63q%252FWQcJKXPyY%252Bo13FwLCMIDhF%252FfBf6%252FamgAWcMuWrv9XGI7WR8oWAOfk%252F2yoQX7VDgFHQ7VB%252BqDl9UeoGqWpD5mGFKwuYgdf8zvwi%252BgjnvlGMeBH4GEHO8C44zit%252FtDYyf7CnMQvdWTwbT5qhCYV7y8giSyS8EWKB3%252FkIQqBz1Zi7kRmmXaYLbqJP4oHRzlG0O2I0fG5dMyCDi5HEQkIVdQQ2nfP%252BfSge3FprJBnhoK1F7530GqEsLEuvB9AbPDJ7%252BKoWoHL71Qfus2%252FKQPzZ9DvSZ7AufPwVE5coFGZEt6YyUdKqaHa%252F%252Fh74uT2t218HMLGQ5JnvGb2yAaMaK00EtvVZ5hpA7nRs1aOnGWLa2aFfuE7KA4gJixMiOQTAzllx8H7ROJj8cPOqwMTicWZ6Wz9vGKbvTW%252FVR3hDt9rjkiPeB2jKOMA5e2sL0meEvr2z6rj%252FrL5uiCaDUul3iRz%252Fhz%252BIuDeqvRrdb22hCmpdu4HQqUtQbOhsMl3YeXlHCPVIwcZzxUjGjcWE%252BvhOx0iSgaFJ0aiwpkecsmqxT%252BBEwy4ymtj1rl27oVElHKgx19bNg8iu5I8dptBW9e1FWNc9%252F9sYZqpB%252F5WZA76p3om0Z5Rby4rNnkZYVZGOOZ3vDdnJgXSFzpu2lLZaYR5YBq8HXNl%7Campid%3APL_CLK%7Cclp%3A2334524 https://www.ebay.com/itm/402816216014?epid=21038233158&_trkp...

      I am not sure if you replied to the correct message but I did mention that modern cars have TPMS. If you are actually arguing against my description of the principles this system works on (monitoring the wheel shape through the rotation speed) then perhaps you should have not posted a link to sensors for such a system. I somehow don't see how a passive device can monitor any pressure least communicate wirelessly. But even if such system existed it would still have been mounted in the wheel, not in the tire on modern cars.

        If I'm reading your posts correctly, you're saying that tire pressure sensors are not mounted in tires of common cars. This may be true in EU and other places where I think monitoring rotation rate of each wheel is typical; in USA, as far as I can tell, most tire pressure monitors are indeed wireless devices mounted inside the tires in connection with the valve stem. This is the case with my car, which is an American variant.

          I am in the USA, all cars I have seen here have valve stem in the wheels (rims). What kind of car you have that has valves in the tire?
