A pneumatic vehicle tyre of radial type of construction, having a tread (), having a carcass inlay (), having electrically nonconductive sidewalls () and having at least one electrically conductive component () or element in a bead region, which component or element, in the case of a tyre mounted on a wheel rim, comes into contact with said wheel rim, wherein either the tread () is electrically conductive or, in the tread region, at least one electrically conductive component () is provided which is overlapped on the outside by the sidewalls () and which is connected in electrically conductive fashion to the tread outer surface, and wherein filaments provided with an electrically conductive coating are incorporated at least in a sidewall region, the coating of which filaments forms electrically conductive passages between the tread () or the component () and the at least one electrically conductive component () or element in the bead region.

Pneumatic vehicle tire

The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.

Method for producing a material web, use thereof as a reinforcing ply for an elastomer item, and vehicle pneumatic tires

A sulfur-crosslinkable rubber mixture, in particular for pneumatic vehicle tires, straps, belts, and hoses, is disclosed which exhibits, among other things, improved rolling resistance behavior. The rubber mixture contains at least the following constituents: 5 to 95 phr of at least one styrene-butadiene rubber, which is functionalized with phthalocyanine groups and/or hydroxy groups and/or epoxy groups and/or silane-sulfide groups and the styrene content of which is 0 to 12 wt % and which has a glass transition temperature (T) according to DSC of &#x2212;75 to &#x2212;120&#xb0; C. in the unvulcanized state, 5 to 95 phr of at least one further rubber, and 20 to 300 phr of at least one silica.

Sulfur-crosslinkable rubber mixture

The invention relates to a pneumatic vehicle tire () of radial design having a carcass () and having components () which adjoin the carcass (), wherein thread-shaped elements () are arranged on at least one of the two surfaces of the carcass () and preferably serve to discharge occluded air between the carcass () and the adjoining components () during the construction of the tire. In order to improve the electrical conductivity of the pneumatic vehicle tire (), at least one thread-shaped element () has a coating which is electrically conductive and jointly forms an electrically conductive, thread-shaped element () which has an electrical resistance of &#x3c;1&#xd7;10Ohm/cm. The invention also relates to a method for manufacturing the electrically conductive coating.

A rubber blend, particularly for pneumatic vehicle tires, harnesses, straps and hoses. The rubber blend includes at least one rubber blend A of a solid styrene-butadiene rubber with an average molecular weight Mof 100,000 to 5,000,000 g/mol and a liquid butadiene rubber with an average molecular weight Mof 500 to 9000 g/mol, wherein the styrene-butadiene rubber is solution-polymerized or emulsion-polymerized, as well as 30 to 300 phr of at least one silicic acid and further blend components.

Rubber blend with improved rolling resistance behavior

A sulfur-curable rubber compound for a tire tread rubber of, in particular, a racing tire, which compound comprises at least one diene rubber, at least one filler and at least one plasticizer. The rubber compound comprises 5 to 90 phr of at least one layered silicate modified with alkylammonium ions and free of guest molecules that have been polymerized or swelled in by a prior treatment.
