ABSTRACT:
A disc road wheel on which a tire is fitted. The disc road wheel has a disc formed with an outer peripheral annular flange section which is press-fitted to the inner peripheral section of a rim. The flange section is formed at its outer peripheral surface with a plurality of gas leak grooves which are aligned along a peripheral direction of the disc. Each gas leak groove is in communication with ambient air even upon press-fitting of the disc and the rim, so that gas between the disc and the rim can be discharged through the gas leak grooves during welding.
