The invention relates to a pneumatic vehicle tyre having a tread (2), which has a shoulder side (2a), a tyre wall (3), and a bead region (4), which tyre is vulcanized in a vulcanization mould having a plurality of segments (8) of a segment ring, which are movably arranged in the radial direction for forming the tread (2) and the shoulder side (2a), a tyre wall shell (7), and a mould partition (Ft), the invention relates to a tyre (1) comprising at least one section (8) for forming a tyre wall (3), a tyre wall shell (7) for forming the outer side of the tyre wall (3), and a mold partition (Ft) between the section (8) and the tyre wall shell (7), in which the shoulder flanks (2a) contiguously adjoin the outer side of the tyre wall (3) together with those areas corresponding to the position of the mold partition (Ft), such that the shoulder flanks (2a) are aligned with the outer side of the tyre wall (3). When the tire is viewed from the side, a portion (3a) of the tire wall (3) is immediately adjacent in each case in the radial interior of a region corresponding to the position of the mold partition (Ft), which portion forms a circumferential flat surface surrounding in the form of a circular ring with a radial range (a1) of 10.00 mm to 25.00 mm, and which portion converges tangentially into the outside of another portion (3b) of the tire wall (3), the other portion has a thin amount of additional material (9) of 0.50 mm to 1.50 mm and is curved outwardly in the form of a circular arc in a radial cross section.
一种车辆充气轮胎,该车辆充气轮胎具有胎面(2)、胎壁(3)和胎圈区域(4),该胎面具有胎肩侧面(2a),该轮胎在硫化模具中硫化,该硫化模具具有部段环的多个部段(8)、胎壁壳(7)和模具分隔部(Ft),多个部段在径向方向上可移动地布置以用于形成胎面(2)和胎肩侧面(2a),胎壁壳用于形成胎壁(3)的外侧,模具分隔部在部段(8)与胎壁壳(7)之间,其中,胎肩侧面(2a)与对应于模具分隔部(Ft)的位置的那些区域一起连续地邻接胎壁(3)的外侧,使得胎肩侧面(2a)与胎壁(3)的外侧对齐。当从侧面观察轮胎时,在对应于模具分隔部(Ft)的位置的区域的径向内部,在各自情况下紧邻胎壁(3)的部分(3a),该部分形成径向范围(a1)为10.00mm至25.00mm的以圆环形式环绕的周向平坦表面,并且该部分切向地汇合到胎壁(3)的另一部分(3b)的外侧中,该另一部分具有0.50mm至1.50mm的薄量的额外材料(9)并且在径向截面中以圆弧形式向外弯曲。
