Publication number: 20140027034Abstract: A vehicle pneumatic tire includes a tread, ply structure, and radial carcass extending around a bead core in each bead region and extending back under the ply structure. Side wall regions are formed by a wing rubber extending from the side of the tread toward the bead region and a rim protection rubber extending from the bead region toward the wing rubber. The wing rubber is the only rubber component extending to the tread and runs in the radially outer portion of the side wall region in contact with the carcass and covers the adjacent rubber component toward the bead region by the radially inner end section of the wing rubber. The adjacent rubber component includes an end section in the covered region narrowing toward the tread, the end of which is located a distance from a base line between 45% and 70% of the height determined therefrom.Type: ApplicationFiled: September 30, 2013Publication date: January 30, 2014Applicant: Continental Reifen Deutschland GmbHInventors: Frank Molzow-Voit, Darren Kidney

Publication number: 20130261272Abstract: A process for producing polymer-functionalized filler particles and polymer-functionalized filler particles obtained by this process. The polymer-functionalized filler particles are used as additives for rubber mixtures. The polymers for functionalizing the filler particles are obtained in-situ starting from filler particles having a surface-bound RAFT agent. The binding of silyl-bearing RAFT agents and of Diels-Alder RAFT agents occurs via the R-group and the subsequent RAFT polymerization proceeds via a reactive site of the RAFT agent.Type: ApplicationFiled: May 24, 2013Publication date: October 3, 2013Applicant: Continental Reifen Deutschland GmbHInventors: Katharina Herzog, Phillipp Vana, Lena Mueller, Bjoern Springer, Carla Recker

Publication number: 20130225766Abstract: A method for processing rubber granules or rubber powders containing different types of rubber. Vehicle tires containing natural rubber in the tread and butyl rubber in the inner liner are granulated or ground to prepare rubber granules or rubber powders, which are processed in a flotation cell under stirring and with the addition of air. The natural rubber fraction of the rubber granules has a higher tendency to adsorb air bubbles and to rise in the flotation cell, while the butyl rubber fraction remains at the bottom. The rubber granules are separated into two or more rubber fractions with an increased amount of a specific rubber type in each fraction.Type: ApplicationFiled: April 4, 2013Publication date: August 29, 2013Applicant: Continental Reifen Deutschland GmbHInventor: Continental Reifen Deutschland GmbH
