A wheel structure, such as for a motorcycle, having a wheel provided with an annular rim which surrounds and is joined to a central support hub through a plurality of radial spokes, which spokes have the outer ends projecting through the rim and rigidly anchored thereto. The rim has a shallow annular groove externally formed in surrounding relationship thereto, which groove includes the region of the rim through which the spokes project. An annular elastic band is positioned within the shallow groove and sealingly engages the bottom wall of the groove. A tubeless inflatable tire can be mounted on the rim, and the interior of the tire is isolated from the spokes and any openings associated therewith due to the elastic band which sealingly surrounds the rim.
