Disclosed is a two-wheeled vehicle pneumatic tire, preferably a bicycle tire, which provides good rolling resistance and good sealing properties, while also improving damage resistance and puncture resistance; the invention relates to a pneumatic tire for a two-wheeled vehicle, comprising, in a bead region (4), a protective layer (8) which is arranged axially outside the carcass and which has a strength member embedded in a rubber material; wherein the tire carcass is formed by a first carcass ply (6) and a second carcass ply (6 ') arranged radially inward of the apex (17), and wherein the second carcass ply (6) ends with a second carcass ply end (7') in the bead region (4) by a second carcass ply fold; the aim of damage and puncture resistance is achieved in that the first carcass ply (6) is guided with a first carcass ply fold (61) from a respective bead region (4) across a respective tire sidewall (3) to below the tread (2) and ends in each case with a first carcass ply end (7) below the tread; and, in each of the two axial halves (20), the protective layer (8) is guided from the bead region (4) to below the tread (2) across the respective tire sidewall (3).
披露了一种两轮车充气轮胎、优选地自行车轮胎,该轮胎在提供良好的滚动阻力和良好的密封性的同时,还改善了防损性和防刺穿性;该两轮车充气轮胎在胎圈区域(4)中具有保护层(8),该保护层设置在该胎体的轴向外侧并且具有嵌入橡胶材料中的强度构件;其中,该轮胎胎体由设置在顶点(17)的径向以内的第一胎体帘布层(6)和第二胎体帘布层(6’)形成,并且其中,该第二胎体帘布层(6)通过第二胎体帘布层翻折部在该胎圈区域(4)中以第二胎体帘布层端(7’)结束;实现了防损性和防刺穿性的目的,因为该第一胎体帘布层(6)以第一胎体帘布层翻折部(61)从相应的胎圈区域(4)跨越相应的轮胎侧壁(3)被引导至该胎面(2)下方、并且在该胎面下方分别以第一胎体帘布层端(7)结束;并且,在两个轴向半部(20)中的每个轴向半部中,该保护层(8)从该胎圈区域(4)跨越相应的轮胎侧壁(3)被引导至该胎面(2)下方。
