Abstract
The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.
