Abstract: A vehicle tire and a method for dissipating heat from a vehicle tire where the tire has sidewalls, an uppermost area over the sidewalls, a bead area and an inner layer, the inner layer being impermeable to air, a rubberized reinforcement-containing carcass, the carcass extending from the uppermost area of the vehicle tire over the sidewalls into the bead area and being anchored in the bead area by looping around bead cores that are resistant to extension, a rubber tread having one or more tread grooves located radially outside, the tread groove having a base and a groove flank, a belt reinforcement with at least one stabilizer belt located between the rubber tread and the carcass, the stabilizer belt containing rubberized reinforcement, a first rubber composition having a first thermal conductivity, and a second rubber composition having a second thermal conductivity at least about 5% greater than the first thermal conductivity of the first rubber composition, the second rubber composition being arranged in t

Abstract: A lamella for use in a vehicle tire vulcanization mold has projections and depression, wherein the height of the projections and the depth of the depressions extend substantially parallel to a peripheral surface of the tire tread of the vehicle tire to be molded in the vulcanization mold. Each one of the projections has a highest point-shaped location or top. Each one of the depressions has a lowest point-shaped location or crater. The projections and depressions are distributed according to a substantially uniform areal division. The areal division is defined by dividing lines extending in a dividing plane preferably centrally positioned between a first plane defined by the tops and a second plane defined by the craters. The dividing lines are comprised of three sets wherein the dividing lines within each one of the sets extend parallel to one another and wherein the dividing lines of different ones of the sets intercept one another at an angle of substantially 60° so that a grid of triangles is formed.

Abstract: A rubber mixture, in particular for the tread of a tire, based on at least one polymer that is from the group of diene rubbers and respectively contains 5 to 100 parts by weight finely distributed, precipitated silicic acid, 0 to 80 parts by weight carbon black, if need be 0.2 to 10 parts by weight silane coupling agent, and 0.5 to 20 parts by weight of at least one non-aromatic, viscosity-reducing substance with regard to 100 parts by weight rubber. The viscosity-reducing, non-aromatic substance is based exclusively on the elements carbon, hydrogen, and oxygen and has a region with at least two hydroxyl groups that exist in the form of 1,2-diol or 1,3-diol, and a region of at least two chemically bonded carbon atoms, wherein neither the chemically bonded carbon atoms nor their chemically bonded neighboring carbon atoms are substituted with oxygen.

Abstract: The lamella fine cut-outs provided in profile elements of the tread surface of a tire, have three-dimensionally structured wall regions. Such wall regions restrict relative movements of the mutually facing wall regions in lateral as well as in radial direction. In such manner there are improved the travel characteristics as well as the wear characteristics like break-outs and irregular wear of such lamella tires.

Abstract: A vulcanizable rubber mixture contains imbedded therein copper alloy based reinforcing elements and forms a durable bond to such copper alloy based reinforcing elements during vulcanization. Therefore, the vulcanizable rubber mixture has added thereto a bonding additive containing at least one monosaccharide which is selected from the group of ketoses. This bonding additive is unobjectionable particularly in toxicological terms and can be admixed and processed without problems. The thus formed vulcanized materials possesses very good characteristics with respect to moisture resistance and oxidative aging.

Abstract: A method of increasing the wear resistance of a vulcanized elastomeric body having a surface region exposed to load, for instance a tire, cone or V-belt, conveyor belt, hose, resilient element, floor covering or the like, by changing its tensile stress state, wherein the elastomeric body is at least partially treated, including the surface region exposed to load, with a swelling agent constituting a medium which is soluble in the elastomer.
