Zusammenfassung:Self-sealing tire sealants are provided which contain fragments and/or residues of expanded solids, where the solids are selected from the group containing expandable graphite and microspheres. In some aspects, the microspheres include at least isobutane and/or isopentane as blowing agents. The microspheres may also have a shell containing at least one polymer, and in some cases the polymer is at least one copolymer of acrylonitrile and methyl acrylate. The self-sealing tire sealant may further include graphene structures. In some aspects the interior of a pneumatic vehicle tire has the self-sealing tire sealant disposed on the inner surface, opposite the tire tread, and the layer thickness of the tire sealant may be from 0.5 to 8 mm.
