Abstract: A tire valve extension attachment connected to tire valve for fascilitating inflation of the tire. The extension attachment comprises a housing, a top element an upper holder element, a lower holder element and a depressing rod, wherein the depressing rod is passed through both holder members and fixedly connected with the top element; the holder members each have protrusions surrounding the depressing rod to limit the transverse movement of the depressing rod. The top element, when the extension attachment is connected to an air pump, is depressed and allows air to pass into the extension attachment from an aperture formed between the top element and the housing and finally through the tire valve to inflate the tire, the depressing rod being simultaneously depressed so as to force the tire valve to open. Every two adjacent protrusions of the holder members have a vent hole in between for air to pass through the holder members in inflating the tire.
