Abstract: A wheel assembly includes a tire having bead seat angle in the range 10° to 12°, preferably 11°, and an aspect ratio of less than 60%. Reduced bounce and improved bead retention is obtained.

Abstract: A wheel assembly includes a tire, having each bead seat angle in the range of 10 degree to 12 degree with respect to the axis of rotation, preferably 11 degree, and an aspect ratio of less than 60%, and a wheel rim, having a circumfurential well and a bead support surface angle also in the range of 10 degree to 12 degree, each bead support surface terminating in an upstanding flange overlapping a radially inner portion of the tire to support the sidewall of the tire. The flanges may be part circular in cross section defining a segment of approximately 135 degree, the radius of curvature being greater than 0.5 inches and preferably 0.75 inches.

Abstract: A wheel for a vehicle comprises a rim disposed about the rotational axis of the wheel and having a pair of axially spaced, circumferentially extending bead seats interconnected by a generally cylindrical base. An annular waffle located in a plane generally perpendicular to the rotational axis is secured to the base intermediate the axial ends thereof. A disk is removably secured to the waffle by way of a plurality of fasteners. The disk and waffle carry co-operating formations which can be brought into mating engagement to allow the disk to be located and held on the waffle at a plurality of different orientations to allow the orientation of the disk with respect to the rim which yields the truest axial alignment of the disk and rim to be determined prior to securing the disk to the waffle via the fasteners.
