Vehicle wheel that includes a pneumatic tire mounted on a wheel rim. The pneumatic tire includes a tire tread, two side-walls, a carcass, reinforcing elements, and two tire beads with bead cores. The vehicle wheel also includes an emergency support body, mounted on the wheel rim and positioned inside the pneumatic tire. The emergency support body includes an emergency rolling surface to support the tire in case of a failure of the pneumatic tire. The emergency rolling surface includes a radially exterior surface of a ring torus with a bowl-shaped cross section, and the ring torus includes axially exterior sections having cross-sectional contours with first curvatures open to the wheel rim and an intermediate section positioned between the axially exterior sections having a contour with a second curvature open to a crest point of the pneumatic tire. The first and second curvatures include at least one radius of curvature and at least one supporting element is positioned to support the ring torus on the wheel rim.

Vehicle wheel with a pneumatic tire

Vehicle wheel includes a rim and a pneumatic tire which includes a tread, two side walls, a carcass, reinforcing elements, and two tire beads with bead cores. An emergency running support body is supported on the rim which is arranged to support one of the pneumatic tire and an interior of the tread in an event of an emergency condition. The emergency running support body includes a shell-shaped ring body located inside the pneumatic tire and an emergency running surface on its exterior. At least one container, which contains a lubricant, is positioned inside a first ring chamber. This Abstract is not intended to define the invention disclosed in the specification , nor intended to limit the scope of the invention in any way.

Vehicle wheel with an emergency running support body and at least one lubricant container

A method for influencing traction of motor vehicle tires made from polymer materials which are mounted and in the operating/driving state, in particular, pneumatic tires for motor vehicles, wherein an ionized gas (plasma) is generated in the vicinity of the surface of the rolling tire that is in the operating state, and wherein the ionized gas is conveyed onto a region of the surface in such a way that the ionized gas acts upon the respective surface region before said surface region rolls into the road contact surface region of the tire.

Method and device for influencing the traction of automobile tires as well as suitable automobile tires for this method

Vehicle wheel including a wheel rim and pneumatic tire having a tread, two side walls and two beads, is mounted to the wheel rim. An emergency running support body is arranged within the pneumatic tire. The emergency running support body comprises a ring-shaped body. The ring-shaped body comprises a first axial outer wall region, a second axial outer wall region, and an emergency running support surface adapted to support the pneumatic tire in an emergency running condition. A first ring-shaped support element is arranged to support the first axial outer wall region. A second ring-shaped support element is arranged to support the second axial outer wall region. At least one of the first and the second ring-shaped support elements comprises a multi-layered structure.
