A unidirectional pneumatic vehicle tire has a symmetric radial carcass and a symmetric package of belt plies placed on the carcass. The tire tread of an asymmetric tread design has at least three longitudinal grooves having a depth of 12 mm to 18 mm. The tire tread has an axially outer wide tread rib, positioned, when mounted on a vehicle, so as to face outwardly relative to the vehicle. The wide tread rib has a width of 25% to 40% of the width of the tire tread when measured at half the depth of an axially outer one of the longitudinal grooves positioned adjacent to the wide tread rib. The wide tread rib is free of any tread voids having a main direction of extension and is selected from the group consisting of longitudinal grooves, longitudinal sipes, transverse grooves, transverse sipes, diagonal grooves, and diagonal sipes. The wide tread rib has tread voids having in a top view of the tire tread a substantially round contour. The tread voids are arranged in 1 to 4 tracks in a circumferential direction of the tire tread, wherein each one of the tracks comprises 100 to 150 of the tread voids.
