  • Patent number: 9233578
    Abstract: A pneumatic vehicle tire has a radial carcass, a sulfur-impregnated rubber mixture which contains 70 to 100 phr (parts per weight related to 100 parts per weight of the entire types of rubber in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, up to 15 phr of at least one soot, 20 to 100 phr of at least one silica, at least one silane coupling agent and one adhesive system. In order to lengthen the service life of the pneumatic vehicle tire, the rubber mixture is the carcass rubber coating and the silica has a CTAB number according to ASTM D 3765 of more than 100 m2/g.

  • Patent number: 9217077
    Abstract: A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, 40 to 70 phr of at least one carbon black and a bonding system. Further, motor vehicle pneumatic tires are disclosed that comprise the sulfur-crosslinked rubberizing mixture. The key conflict between tear propagation resistance, stiffness and heat build-up is solved by virtue of the carbon black being a nanostructured carbon black with a rough surface.

  • Patent number: 9150714
    Abstract: A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, up to 15 phr of at least one carbon black, 20 to 100 phr of at least one high-dispersibility silica, at least one silane coupling agent and a bonding system. The invention further relates to motor vehicle pneumatic tires comprising the sulfur-crosslinked rubberizing mixture. For improved resistance to cracking and growth of cracks with good adhesion and good mechanical and dynamic properties, the high-dispersibility silica has a CTAB number to ASTM D 3765 of more than 130 m2/g.
