Goodyear has developed a new self-inflating tire for commercial vehicles. The Air Maintenance Technology system uses an internal pressure regulator to determine when the tire is low. When pressure falls above a certain parameter, the regulator opens to allow air into a pumping tube. Here's the cool part: the tube runs around the circumference of the tire, and as tire rolls, it squeezes the tube, effectively forcing air into the tire through an inlet.
