The present invention relates to a wheel having a rim portion 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 equally spaced 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 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.
