System, apparatus and method for adjusting air pressure in a tire

A system for adjusting air pressure within a tire of a vehicle, comprising:

• a pressure adjustment device including a housing formed from a cap and a base, the housing including a piston and an air valve, a neck extending from a distal portion of the base, wherein a distal end of the neck is configured to couple with the tire, wherein the cap is removably couplable to the base;
• and,
• a spring,
• wherein the cap includes an air inlet and the base includes an air outlet that is in fluid communication with the neck, wherein the spring is located proximal the piston,
• wherein the piston and the spring are configured such that the piston moves proximally to compress the spring in response to a presence of a centrifugal force due to the vehicle traveling at least at a predetermined speed, wherein proximal movement of the piston activates the air valve thereby enabling fluid to flow into the housing, and
• wherein the spring is configured to decompress when the centrifugal force decreases thereby deactivating the air valve and compressing the fluid within the housing distally out the air outlet toward the tire.
