Pneumatic vehicle tyres which have a bandage ply (8) comprising two lateral portions (10) and a center portion (12) in the axial extension, wherein each lateral portion (10) has at least one hybrid reinforcement, and wherein the center portion (12) has at least one reinforcement which has a lower modulus of elasticity than the hybrid reinforcements of the lateral portions (10), in each case measured as per ASTM D885M at an elongation of 3%. It is the object of the invention to provide a tyre with reduced rolling resistance and good high-speed characteristics with reliable producibility. This is achieved in that the hybrid reinforcement is a hybrid cord made of at least one low-modulus thread and one high-modulus thread twisted together, and in that the hybrid reinforcement has a fineness of at most 550 dtex, preferably at most 500 dtex, particularly preferably at most 460 dtex, and in that the reinforcement of the center portion (12) has a fineness of at most 1100 dtex, preferably at most 600 dtex, particularly preferably at most 500 dtex.
