Title: Cast vehicle wheels

Abstract: A light-alloy vehicle wheel comprises a nave, a wheel disc with ventilation apertures, two opposed tire bead seats and a well lying between the bead seats. A plurality of external, equally-spaced webs extends between the outer face of the wheel disc and one of the tire bead seats on its outer face and a corresponding plurality of internal fillets lie between adjacent ventilation apertures. Each fillet has an inwardly-directed face preferably of convex cross-section such that the corners of the cross-section defining the adjacent ventilation apertures are closer to the neutral axis of the local cross-section of the wheel disc, than the convex face of the fillet.
