Abstract: A tire filter assembly (15, 400) for a central tire inflation system (10) having fluid communication (403) from the exterior to the interior of the pressurized chamber (74) of an inflatable tire (12). The assembly includes filter means (15) mounted to a cylindrical sleeve-type bead lock (400) inside the interior pressurized tire chamber (74). The location of the filter inside the tire permits it to have a relatively large area through which air can flow, and to prevent rubber particles that come off the inside of the tire from entering the central inflation system. The filter assembly is affixed by means of an adhesive (11) or a molding material to a groove (17) provided in the bead lock, and/or by mechanical means.
