    Abstract: A pneumatic vehicle tire for commercial vehicles includes a belt having five belt plies having respective sets of reinforcements. The five plies are identified as first, second, third, fourth and fifth plies. The third ply is a 0° ply and the second and fourth belt are working belt plies. The sets of reinforcements of the first and second plies lying adjacent one side of the 0° ply run upward at respective positive slopes and the sets of reinforcements of the fourth and fifth plies lying adjacent the other side of the 0° ply run upward at respective negative slopes. The reinforcements of the fifth ply and the peripheral direction (A-A) of the tire conjointly define an angle φ between 35°≦φ≦70°. The reinforcements in the second and fourth plies having an elongation of ≧0.2% at 10% breaking load. The elongation is measured using reinforcements taken from a fully vulcanized tire.
