A regulator in the tire senses when tire-inflation pressure drops below a pre-set point and opens to allow air flow into the pumping tube. As the tire rolls, deformation flattens the tube, pushing air through the tire to the inlet valve and then into the tire cavity.All this technology, in Goodyear’s words, eliminates the need for “external inflation pressure intervention.”

There is a picture also in the article as to how this works.

This would be great.

Such marvellous things are based on so simple principles. The idea seems obvious after someone else has thought of it. We'll probably be seeing this on premium vehicles in the very near future. I hope they have a capable filter for Indian dust and humidity.
