Goodyear Debuting Self-Inflating Tires at IAA
It uses a clever system of valves and a sensor which do not require any outside power supply, pump or electronics. Once the sensor detects a drop in pressure, it will open several valves located around the inner edge of the tire, and the simple movement and deformation of the tire is enough for air to be forced into the tire, thus inflating it on the go, without any intervention of any kind.
The system is designed for commercial vehicles, an area in which tire pressure, which is linked to fuel efficiency, is extremely important. We say that if the system proves itself in commercial vehicles, it will be adapted and adopted for regular road car use within a few years.

In the first paragraph of your article you stated, "venue chosen by Continental to debut." I thought the article was about Goodyear, please, clarify.
