Abstract

A pneumatic vehicle tire has a tire tread with circumferential grooves. Each one of the circumferential grooves has a groove base and groove flanks. At least one of the circumferential grooves has a wiper rib member connected integrally to the groove base and extending over the entire circumferential length of the circumferential groove such that the wiper rib member is connected to the groove base but is separate from the groove flanks. The wiper member has, when viewed radially outwardly, a lower portion and an upper portion, wherein the upper portion is divided by transverse grooves into member sections and the lower portion is continuous in the circumferential direction. The transverse grooves are slanted at an angle of 10.degree. to 40.degree. relative to the axial direction. The transverse grooves comprise a first set and a second set, with the transverse grooves of the first set oriented opposite to the transverse grooves of the second set. The transverse grooves of the first set alternate with the transverse grooves of the second set such that the member sections of the wiper rib member have a trapezoidal contour.
