Abstract
An apparatus to maintain optimal air pressure in a tire of a vehicle may use centrifugal force to compress air which may be delivered to the tire when the tire has low air pressure. The necessary centrifugal force to compress air may be achieved through the rotation of the tire itself. A weight may be disposed, in a chamber, near the center of rotation of a tire. The weight may be held in place with a spring or similar device. As the tire rotates, the weight may be forced outward, compressing air present in the cylinder. If the air pressure within the tire is low, the weight will compress air from inside the cylinder into the tire. The apparatus may act autonomously to add air to a low pressure tire, as opposed to simply notifying the driver that tire pressure is low.
