ABSTRACT:
A full face type cast wheel, wherein a rim portion holding a tire and a disk portion connected to the rim portion are integrally cast, includes a side wall portion extending from a dropped portion of the rim portion to a bead seat portion of the rim portion and a plurality of recessed portions defined intermittently in the circumferential direction of the wheel on a surface of the side wall portion facing the inside of the tire. By formation of the recessed portions, the weight of the wheel can be decreased, generation of blowholes in a casting process can be prevented and air capacity of the tire can be increased.
