I have a ballast (liquid) rear tire that is low on air. At the top of the stem contains a sphere that if you depress it it will release air (tire is rotated to position the valve stem at the top of the tire). It is appears to be a screw cap, that when you loosen it it will also leak air.
It is not a schrader valve, nor will a standard air gauge or air nozzle fit it. Does anyone know what type of valve this is and what attachment or tool I need to fill it with air? I don't want to experiment with unloosening the cap totally for fear of losing all my air pressure that is remaining.
Thanks
