The invention is directed to wheel (1) comprising a rim (2) and a wheel center (3). The wheel center (3) comprises and insert (10) which at least comprises a front pad (11) and a rear pad (12) which are a distance apart with respect to each other and which are at least partially embedded in a composite material (6).

A disc portion and a rim portion of a tire wheel are integrally formed simultaneously, with a resonance pipe formed between the disc and rim portions, by inserting a molten metal into a space formed by a mold combined with the resonance pipe by core pins.

A motorcycle wheel is provided, in particular a motorcycle wheel suitable for use on an enduro motorcycle. The wheel includes a cast or forged rim having integrally spokes which extend toward a central hub connection region. The central hub connection region is configured to receive a hub element in a detachably fastened manner. The hub element forms a hub of the motorcycle wheel which is connectable to a motorcycle.

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.

The present invention relates to a hubless one-piece wheel comprising: a rim; and a disc integrally formed at the rim and formed by low-pressure casting, wherein the disc is a hubless type including a plurality of spokes and a space at the center of the rim. One side of said each spoke is integrally formed at the rim, and a lug hole is formed in the other side of said each spoke for coupling the wheel to a vehicle body. The plurality of spokes are radially arranged inside the rim, and each of the other sides of the spoke locates in the inner center portion of the rim being separated by the space.
