A wheel includes a rim having an outer radius, R1, extending from a center point of the wheel to an outer edge of the rim, and a hub having an outer radius, R2, extending from the center point of the wheel to an outer edge of the hub. The hub is positioned coaxially with the rim and has a plurality of circumferentially positioned and equiangularly spaced bolt holes for attachment of the wheel to the vehicle. The wheel further includes a plurality of equiangularly spaced, Y-shaped spokes having a trunk portion contacting the hub, two limb portions each contacting the rim, and a branch point at which the trunk portion and limb portions converge. The spokes extend radially outward from the hub to the rim. The bolt holes are interspaced between the trunk portions. A distance between the center point of the wheel and the branch point is D1. |

1. A wheel for a motor vehicle, the wheel comprising:
an annular wheel rim having a first outer radius, R1, extending from a center point of the wheel to an outer edge of the wheel rim; an annular wheel hub having a second outer radius, R2, extending from the center point of the wheel to an outer edge of the wheel hub, the wheel hub positioned coaxially with the wheel rim and having a plurality of circumferentially positioned and equiangularly spaced bolt holes for attachment of the wheel to the motor vehicle; and a plurality of equiangularly spaced, Y-shaped spokes having a trunk portion contacting the wheel hub, two limb portions each contacting the wheel rim, and a branch point intermediate the trunk portion and limb portions, the spokes extending radially outward from the wheel hub to the wheel rim, wherein the bolt holes are interspaced between the trunk portions of the spokes, wherein the trunk portion and the limb portions converge at the branch point, wherein a distance between the center point of the wheel and the branch point is D1, wherein R2/R1 is between 0.2 and 0.4, wherein D1/R1 is between 0.4 and 0.6, and wherein an internal angle between the two limb portions of each Y-shaped spoke is between 100 degrees and 120 degrees. |
