Abstract: A double inner tube and valve system for use in a wheel assembly including a circular rim with a base wall and opposing radially extending flanges defining a well, and an aperture formed in said base wall. A tire is mounted on the rim, and defines an annular cavity in conjunction with the rim. The double inner tube is positioned in the annular cavity and defines an inflatable primary tube adjacent to the tire, and an inflatable secondary tube positioned between the primary tube and the rim. A valve assembly is attached to the double inner tube and positioned in the aperture in the rim. The valve assembly comprises a primary valve in fluid communication with the primary tube to allow inflation of the primary tube and a secondary valve which replaces the primary valve and is in fluid communication with the secondary tube for inflation of the secondary tube. The valve assembly is selectively configurable to inflate the primary tube or the secondary tube.
