Claim Text:
1. A vehicular wheel comprising: a hub; a rim; and a plurality of spokes interconnecting the hub and the rim, the spokes extending from the hub toward the rim in the radial direction and arranged around the hub in the circumferential direction; the hub, the rim and the spokes being formed as an integral body by casting, wherein: a plurality of weight-mounting surfaces are formed at the center of an inner peripheral surface of the rim in a widthwise direction of the wheel, each weight-mounting surface being arranged between connecting portions of adjacent spokes where the spokes are connected to the rim, respectively, and a molding seam, formed at an interface between split faces of a wheel mold used to cast the wheel, is spaced away from a central portion of each of the weight-mounting surfaces in the widthwise direction, such that a substantially unobstructed area of each weight-mounting surface is provided to receive a weight thereon, wherein the weight-mounting surface is offset from a rotational center line of the wheel by an angle D which is in a range from 0.5° to 3° with respect to the rotational center line of the wheel, wherein the wheel is formed by high-pressure die casting, and wherein the weight mounting surfaces are disposed circumferentially between connecting portions of adjacent spokes and between inner and outer surfaces of the spokes in the widthwise direction of the rim.
