The present invention relates to a wheel comprising a hub formed inside the wheel, a rim portion separated outwardly from the hub and forming a circumference on which a tire is fitted, a plurality of spokes connecting the hub and the rim portion, wherein the rim portion is characterized by including an air-tight rim formed in a cylindrical shape, and a protruded grid portion having a plurality of first recesses by being protruded from and equispaced around the circumference of the air-tight rim. In this way, the honeycomb rim-type wheel can be readily manufactured to have lightweight using a single casting job without sacrificing durability thanks to the protruded grid portion on the circumference of the air-tight rim, thereby reducing time and cost for manufacturing by reduced usage of molten metal.
