Abstract: A sealing preparation for tire problems is proposed which seals in wet conditions, at low and high temperatures and with defects at the transition between the tread and the side wall of the tire. The sealing preparation contains natural rubber latex or a combination of rubber latex and compatible adhesive resin. Furthermore, various devices are proposed for introducing the sealing preparation into the tire and for the pumping up. An air compressor, or liquefied dinitrogenoxide, or sulphur hexafluoride are preferably used with these devices as a pressure source.

Abstract: Preparations for the sealing of tires with punctures are proposed, which contain the latex of synthetic isoprene rubbers or the latex of natural rubber together with latexes of synthetic isoprene rubbers, acrylate rubbers and/or methacrylate rubbers. The sealing preparations can contain an adhesive resin compatible with the latexes from the group comprising polyvinyl esters, polyvinyl alcohol and/or polyvinyl pyrrolidone, and also a pigment, with natural rubber latex, synthetic rubber latexes or their mixtures being used as rubber latex. Furthermore, an apparatus is described for the sealing and pumping up of the tire using an airbag inflation charge and also tires with an integrated sealing preparation.

Abstract: A method and apparatus for removing puncture sealing compositions from a tire, characterized by allowing air pressure to flow out of the tire via the valve, removing the tire valve, introducing a hose into the tire through the valve bore until the introduced hose end dips deeply into the sealing preparation contained in the tire and generating a pressure differential so that the sealing preparation is removed through the hose.

Abstract: The invention relates to a container for the sealing of tires with punctures, with which it is possible to first mix a liquid sealant and a filler when sealing is to take place, but to keep them separate during the prior storage. The container has a first chamber for filler and a second chamber for the liquid sealant. The chambers are fixedly or movably connected together and at least one of the chambers can be compressed. Between the chambers there is a partition wall, which consists at least in part of a rupturable member which is torn so that the liquid sealant and the filler mix before injection of the mixture into the tire via an outlet valve by compression of the chamber.

Abstract: Rubber mixtures vulcanisable with sulphur are proposed which lead to tires with a good rolling resistance and driving behavior on wet roads without the other driving characteristics deteriorating. The rubber mixtures contain a copolymer of conjugated diene and vinyl aromatic compound manufactured by emulsion polymerisation, polyisoprene, polybutadiene, silica, carbon black in a specific range of quantities and also customary additives and a vulcanisation system. A further embodiment additionally contains copolymer manufactured by solution polymerisation in specific quantity ranges, and in this embodiment the polyisoprene is an optional component.

Abstract: A rubber mixture vulcanizable with sulphur, a tire tread manufactured from it and also tires with a vulcanized tread are proposed. The rubber mixture contains in each case 100 parts by weight of elastomers, 20 to 80 parts by weight of a copolymer of conjugated diene and vinyl aromatic compound with very low long chain branching manufactured by solution polymerization in a hydrocarbon solvent, 10 to 50 parts by weight of polybutadiene with very low long chain branching, 10 to 30 parts by weight of polyisoprene with a 3,4 bond content of 50 to 70% by weight and 30 to 100 parts by weight of silica as filler material. Through the special combination of the three elastomers with silica as a filler material one obtains an easily processable mixture which leads to vulcanized tire treads with improved grip on wet and dry surfaces.

Abstract: A caoutchouc mixture vulcanisable with sulphur, tire treads manufactured therefrom and also tires with these vulcanised tire treads are proposed. The caoutchouc mixture contains 30 to 100 parts by weight of isoprene-butadiene copolymer, 0 to 70 parts by weight of one or more further elastomers, 20 to 90 parts by weight of silica as a filler material, customary additives and also a vulcanisation system, with all parts by weight being related to 100 parts by weight of total elastomers. This caoutchouc mixture delivers tire treads with good resistance to abrasion and a low loss factor which is correlated with a low rolling resistance.
