The Air Maintenance Technology (AMT) system will be able to automatically ensure your four tires remain inflated to the optimum pressure, and this is achieved without requiring any external pumps or electronics. In fact, the entire system’s components will be contained within the tire itself. Right smack at the system’s heart lies an internal regulator which is capable of detect whenever the air pressure drops below a pre-specified psi, where it will then open up to allow air from outside the tire to be sent into the pumping tube. Air will then be pushed through this tube to the inlet valve, which ensures optimal pressure is maintained.
Right now, Goodyear will target their AMT system at commercial vehicle fleet operators, although we should be able to see glimpses of it appear on everyday sedans in due time.
