Abstract
A pneumatic vehicle tire having a carcass with textile carcass strength elements, a belt arranged radially outside the carcass, and a belt bandage ply of a belt bandage arranged radially outside the belt, wherein the belt bandage ply has textile cords as strength elements, which are arranged substantially parallel to one another and are embedded in elastomeric material, wherein the cords each have precisely two yarns, wherein the two yarns are yarns of polyamide 6.6 (PA 6.6), which have the same linear density and are end-twisted together to form the cord.
