A rim for a vehicle wheel having an inner and an outer rim flange, an inner and an outer rim shoulder, a rim well with well base, inner well flank and an outer well flank, a transition section and an inner hump with a hump peak. The rim is having specific material thickness in the area of the transition section. In order to improve wheels in terms of weight minimization and noise development, the transition section comprises at least one stiffening section with a radially offset wall section, the maximum radial offset of which to the adjoining transition section is greater than the material thickness in the transition section. The stiffening section has a diameter, being equal or greater than the diameter on the well base and smaller than diameter of the hump peak.

Vehicle wheels and methods of making vehicle wheels are provided. A vehicle wheel comprises a generally annular first region, a second region, and a flange extension. The first region comprises an inner surface and an outer surface comprising a tire bead seat. The second region extends radially inwardly from the first region. The second region is configured to mount to a vehicle axle. The flange extension extends from the first region in a direction away from the second region. The flange extension comprises a first extension end integral with the first region, a second extension end, and an elongate portion intermediate the first extension end and the second extension end. The elongate portion comprising a first portion with a thickness less than a thickness of the second extension end.

The present invention relates to an in-wheel motor. The in-wheel motor according to an embodiment of the present invention includes: a circular rim to which a tire is coupled by being wrapped around an outer ring thereof and a shaft is connected by passing through a center thereof; a motor assembly which is disposed in an inner portion of the rim and includes a stator connected to the shaft and a rotor disposed to be wrapped around the stator and configured to rotate; a cover coupled to cover one open side surface of the rim and configured to seal the inner portion of the rim; and a lead-out wire entry/exit portion waterproof structure configured to seal an entry/exit portion for a lead-out wire connected to supply power from outside of the in-wheel motor to the inner portion of the rim via a hollow portion of the shaft, wherein the lead-out wire entry/exit portion waterproof structure includes an elastic stopper, to which the lead-out wire is connected to pass through a center thereof and which is configured to be elastically contracted after being inserted into the hollow portion of the shaft in an axial direction and seal between the hollow portion of the shaft and the lead-out wire, and a stopper fixing body fastened to the shaft and configured to press the elastic stopper in the axial direction so that the elastic stopper is inserted and fixed inside the hollow portion of the shaft.

Vehicle wheels and methods of use are provided. The vehicle wheel comprises a first region, a second region, and a third region. The first region is generally annular and comprises a first flange, a second flange opposite the first flange, and a continuous wall comprising an inner surface and an outer surface. A first tire bead seat and a second tire bead seat are defined on the outer surface. The second region is configured to mount to a vehicle axle and is offset from the first flange by an offset distance. The third region connects the second region and the third region and extends inwardly towards the longitudinal axis from an attachment location on the first region to the second region. The third region comprises a first thickness and the second region comprises a second thickness. The first thickness is no greater than 75% of the second thickness.

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be greater than the average thickness (T2) of the rim part. In other words, the relation T1>T2 holds.
