Abstract
The invention relates to a hybrid cord for use as a reinforcement in a belt bandage of a pneumatic vehicle tire, consisting of at least two threads with ends which are twisted together. At least one first thread is a high-modulus thread with a specified thread fineness, and another thread is a low-modulus thread, said other low-modulus thread having a lower thread fineness than the first thread. The invention is characterized in that the proportion of the high-modulus thread in the hybrid cord is 80-95 wt. %; the difference between the thread fineness of the high-modulus thread and the thread fineness of the other low-modulus thread is >800 dtex; and the elongation at break of the high-modulus thread ranges from 1%-8%, and the elongation at break of the low-modulus thread ranges from 9%-30%.
