SternisheFan writes with a bit of maintenance saving tech for drivers. From the article: "When was the last time you checked your tire pressure? If you're scratching your head, you might want to put a set of Goodyear's new self-inflating tires on your ride. The company's Air Maintenance Technology was rolled out of the lab this week for debut at a car show in Germany. Commercial truckers will be the first to put the rubber to test, but a consumer version is in the works. 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.'"
