The invention relates to a sulfur vulcanizable rubber mixture. Furthermore, the invention relates to a pneumatic vehicle tire whose Notlaufeinlage in the sidewall region, the apex and / or its Humpstreifen from the sulfur-vulcanized rubber mixture, and a Notlaufstützring for pneumatic vehicle tires, make its contact with the rim-producing feet of a sulfur-vulcanized rubber mixture. For high hardness and rigidity in the application, the rubber mixture contains at least one diene elastomer, at least one filler, - At least one acting as a plasticizer polymer, which can be crosslinked with a di- or polyisocyanate to polyurethane, and - At least one blocked di- or polyisocyanate, which is split back only at temperatures of> 140 ° C. |
