Abstract: The invention relates to a sulfur-crosslinkable rubber mixture, to the vulcanizate thereof, and to a vehicle tire. The rubber mixture according to the invention comprises at least the following constituents: at least one diene rubber; and, at least one char (HTC char) obtained by hydrothermal carbonization of at least one starting substance. A vehicle tire according to the invention comprises at least one vulcanizate according to the invention of the rubber mixture in at least one component.

Abstract: A sulfur-crosslinked rubber mixture for vehicle tires including carbon nanotubes (CNT), to a vehicle tire comprising the sulfur-crosslinked rubber mixture and to a process for producing the sulfur-crosslinked rubber mixture comprising CNT. The sulfur-crosslinked rubber mixture according to the invention is characterized in that the CNT are predispersed in at least one polyisoprene. The vehicle tire according to the invention preferably comprises the sulfur-crosslinked rubber mixture in the tread and/or a sidewall and/or a conductivity track.
