The invention relates to a pneumatic vehicle tyre having a tread and side walls, the tread having at least one shoulder-side profile rib (1, 1 ') having a shoulder portion (1b) which extends from a lateral edge (L) of a ground-contacting surface of the tread in the direction of the respective side wall and has an outer surface (1d), the invention is characterized in that it comprises rectangular recesses (2), which are elongated transversely to the circumferential direction and each free radical (6) and are delimited in the circumferential direction by side surfaces (7), the base (6) has an inner base portion (6a) extending towards the outer face (1d) and having a maximum extension (ca) and an outer base portion (6b) having a maximum extension (cb). The maximum extension (cb) of the outer base portion (6b) is equal to 55% to 85% of the maximum extension (cb) of the inner base portion (6a), the outer base portion (6b) terminates in a direction towards the side wall in an end side face (8) which extends towards the outer face (1d) of the shoulder portion (1b) and has a delimiting edge (8a) on the outer face (1d) of the shoulder portion (1b), the delimiting edge (8a) being located on the outer face (1d) of the shoulder portion (1b), and the delimiting edge (8a) being located on the outer face (1d) of the shoulder portion (1b). Viewed in a cross-section oriented transversely to the circumferential direction, the end flank (8) encloses an angle (eta) of 80 DEG to 100 DEG with an outer face (1d) of the shoulder portion (1b).

    本发明涉及一种车辆充气轮胎,该车辆充气轮胎具有胎面和侧壁,其中,该胎面具有至少一个胎肩侧胎纹肋(1,1'),该胎肩侧胎纹肋具有胎肩部分(1b),该胎肩部分从该胎面的地面接触面的侧向边缘(L)沿相应侧壁的方向延伸并具有外部面(1d),并且包含矩形凹陷(2),这些矩形凹陷形成为横向于周向方向伸长并且各自由基部(6)并且沿该周向方向由侧部面(7)界定,其中,在横向于该周向方向的截面中观察,该基部(6)具有朝向该外部面(1d)延伸且具有最大延伸长度(ca)的内侧基部部分(6a)以及具有最大延伸长度(cb)的外侧基部部分(6b)。该外侧基部部分(6b)的最大延伸长度(cb)等于该内侧基部部分(6a)的最大延伸长度(ca)的55%至85%,其中,在朝向该侧壁的方向上,该外侧基部部分(6b)终止于端侧面(8),该端侧面朝向该胎肩部分(1b)的外部面(1d)延伸并且具有位于该胎肩部分(1b)的外部面(1d)上的界定边缘(8a),其中,在横向于该周向方向定向的截面中观察,该端侧面(8)与该胎肩部分(1b)的外部面(1d)围成80°至100°的角度(η)。
