Michelin has been selling these under the "Tweel" name[0] for skid steers, commercial lawn mowers, and other mid-sized wheeled equipment for several years now. Supposedly, they improve the handling and ride of the equipment since the Tweel's internal structure flexes more than an air-filled tire and therefore adds more of a suspension to the tractor.
