A support assembly for a vehicle includes at least two spherical tires travelling on a road surface and rotating relative to the road surface and the vehicle and a drive system magnetically driving rotation of the tires relative to the drive system itself such that no portion of the drive system physically contacts the tires or the road surface. The tires each have an outer tread layer comprising a material having a first stiffness when dry and a second stiffness when wet, the first stiffness being greater than the second stiffness.

Active tire orientation and pressure adjustment systems and methods of use in response to a plurality of activation conditions can ensure efficient tire orientation and pressure modes are active when necessary to balance tire traction and driving range of an electric vehicle. The activation conditions can be customized based on driver preferences to help ease range anxiety while providing a balance with vehicle traction.

A wheel assembly, a wheeled device and a method of manufacturing a wheel assembly. The wheel assembly includes a core and an outer portion coupled to the core. The core includes a body and one or more projections extending from the body. Material of the outer portion may be positioned radially between the body and a portion of the projection to limit radial movement of the outer portion relative to the core. The projection may define a bore and/or an undercut. Material of the outer portion may encompass the projection and fill the bore and/or the undercut. Engagement of the material of the outer portion and the projection(s) may limit relative movement between the core and the outer portion radially, axially, circumferentially, etc.

The application relates to a deformable wheel with non-pneumatic load bearing intended to equip a vehicle for rolling under extreme conditions such as those encountered on the Moon and on Mars, comprising a hub, an annular tread intended to be in contact with the soil, positioned around the hub which is concentric therewith and comprising a layer of composite material coated with at least one protective layer, and a plurality of metal cables whose outer diameter is comprised between 0.2 mm and 5 mm, each cable connecting the hub to the tread while being fixed, on the one hand by an external end to the tread, and on the other hand by an internal end to the hub by an elastic member making it possible to modulate the radial stiffness of the cables, each elastic member being associated with an abutment able to limit its deformation.
