Lustiga hjul på en B25, någon som vet vad detta är?

Can anyone figure this one out? This landing gear was photographed mounted to a B-25 belonging to the Bendix corporation.



I couldn't find any further explanation of the gear design with the picture. It appears that the wheel's axle is mounted very much off center on the wheel, with a very thing rubber tire. The rubber strip around the wheel may freely rotate like a tracked gear system, but I can't find any evidence for or against that theory. If it really is just an off-center wheel, this must be one helluva bumpy ride.
