The invention relates to a commercial vehicle tyre, comprising a tread having at least one profile rib (1) which is circumferential in the circumferential direction, is arranged on the side of the equatorial plane of the tyre, and has transverse cutouts (12), each of which has a cutout wall (12a), a cutout center plane (fE) which is kept at a distance from the cutout wall (12a), and a cutout center plane (fE) which is arranged at a distance from the cutout center plane (fE), the cutout center plane (fE) being arranged between the cutout wall (12a) and the cutout center plane (fE). The cut-out has a width (bE) of 0.4 mm to 2.0 mm and has a maximum depth (tE) in the radial direction, which is at least 40% of the profile depth (TP), wherein each cutout (12) has at least one cutout region (12II), which is formed by breaking away from the radially outer cutout periphery and extends in the direction of extension of the cutout (12) in a corrugated shape and in the radial direction in an arc-shaped or single-pointed shape, at least in a section extending over its majority in a top view, wherein a plane (F1) extending through the position of the maximum deflection of the cutout region (12II) and the cutout center plane (fE) have intersecting lines (l1) following the corrugated shape of the cutout region (12II). The cutouts (12) extend only in the cutout regions (12II) in a corrugated shape, in which the amplitude of intersection lines (1) following the corrugated shape of the cutout regions (12II) decreases in respective intersection line sections (11 ') extending a half wavelength ([lambda]/2) in the direction of the tread-outside cutout ends (12c).

    本发明涉及一种商用车辆轮胎,该商用车辆轮胎具有胎面,胎面具有在周向方向上环绕的、布置在轮胎赤道面的侧面的、带有横穿的切口(12)的至少一个胎纹肋(1),切口各自具有切口壁(12a)、与切口壁(12a)的间隔保持一致的切口中心平面(fE),切口具有0.4mm至2.0mm的宽度(bE)并且在径向方向上具有最大深度(tE),该最大深度是胎纹深度(TP)的至少40%,其中每个切口(12)至少在俯视图中于其大部分上延伸的区段中具有相对于径向外部切口外围断离形成的、在切口(12)的延伸方向上以波纹形状且在径向方向上呈弧形或单尖形延伸的至少一个切口区(12II),其中延伸穿过切口区(12II)的最大程度偏转的位置的平面(F1)与切口中心平面(fE)具有遵循切口区(12II)的波纹形状的交线(l1)。切口(12)仅在切口区(12II)中以波纹形状延伸,其中遵循切口区(12II)的波纹形状的交线(l)的波幅在延伸一半波长(λ/2)的各个交线区段(l1')中朝胎面外侧的切口端部(12c)的方向减小。
