Abstract
A pumping assembly keeps a pneumatic tire from becoming underinflated. The pumping assembly includes an even number of pumps attached to the tire rim, a gravity mass for producing a pumping action, a cam fixed to the gravity mass for maintaining the cam in a fixed position relative to the gravity mass, and rollers for engaging the cam and producing the pumping action as the tire rim rotates and the gravity mass retards rotation of the cam as the tire rim rotates.
