The surface of at least a portion of an interface element common to one of the voids has an edge radius with a variation from a maximum radius at a circumferential location corresponding to a mid point between a pair of adjacent web spokes to a minimum radius at a circumferential location corresponding to the intersection of the interface element with the web spoke.
