Beschreibung
Zusammenfassung:	A pneumatic tyre for a motor vehicle. The pneumatic tyre comprises a first sidethat is an inner side of the pneumatic tyre, and an opposite second side. A leasta part of the pneumatic tyre comprises rubber-based material that is configured5to restrict gas permeability and that comprises lignin that has been treated byhydrothermal carbonization. The rubber-based material or a coating of therubber-based material forms at least a part of the first side of the pneumatic tyre.A method for manufacturing a pneumatic tire. L'invention concerne un pneumatique pour véhicule à moteur. Le pneumatique comprend un premier côté qui est un côté interne du pneumatique et un second côté opposé. Au moins une partie du pneumatique comprend un matériau à base de caoutchouc qui est conçu pour limiter la perméabilité aux gaz et qui comprend de la lignine qui a été traitée par carbonisation hydrothermale. Le matériau à base de caoutchouc ou un revêtement du matériau à base de caoutchouc forme au moins une partie du premier côté du pneumatique. L'invention concerne également un procédé pour la fabrication d'un pneumatique. FIG. 1a : SR%%%SR SAX%%%SAX
