How often do you check on your tires? As much as we'd like to say it, we don't do it much ourselves. A vehicle's tires should be properly inflated for the reasons of better safety to safer handling and more. But now, Goodyear has made it much more easy with its new Air Maintenance Technology System. The tire will automatically keep itself at the proper PSI using a self contained passive pump!

While auto-inflation tires have been around for a while now, they involve complicated valves and tubing to connect each tire to a pump in the vehicle. But Goodyear has a better product. They use an internal regulator that automatically opens when tire pressure is low to let air in to a pumping tube.

When the tire rolls and is deformed, the air inside the tube is squeeze into the tire's main cavity pumping it back up. Quite genius actually. There's also less risk that the components get damaged because the system is self contained.

There's no pricing or availability information just yet, but the company will be showing off the tires at the 2013 Internationale Automobil-Ausstellung Commercial Vehicle Show in Germany.
