    • A pneumatic tire including a separatable pair of mechanical fasteners wherein a first fastener of the pair of mechanical fasteners is provided on a tire inner surface. In this pneumatic tire, the obtained engagement force of the pair of mechanical fasteners is great and is essentially free of variations (positional variation within the tire and variation from tire to tire); the engagement force deteriorates/declines minimally over time due to extreme usage conditions including repetitive deformation and compaction over an extended period of time caused by tire rotation at high speeds in a state of relatively elevated temperatures; and the desired engagement force can be maintained over an extended period of time.
    • 一种充气轮胎,其包括可分离的一对机械紧固件,其中所述一对机械紧固件中的第一紧固件设置在轮胎内表面上。 在该充气轮胎中,所获得的一对机械紧固件的接合力大,并且基本上没有变化(轮胎内的位置变化和从轮胎到轮胎的变化); 由于极端的使用条件包括重复变形和在相对升高的温度下高速轮胎转动引起的延长的时间段内的压实,接合力随时间而劣化/降低; 并且可以在延长的时间段内保持期望的接合力。

    • Provided is a pneumatic tire manufacturing method capable of improving the productivity of pneumatic tires each having surface fasteners in its tire inner surface, and of avoiding manufacturing a pneumatic tire having a deteriorated uniformity, as well as of preventing engagement elements of each surface fastener from being crushed. Also, provided is a pneumatic tire manufactured by the pneumatic tire manufacturing method. The pneumatic tire manufacturing method according to the present invention includes the steps of, in making a green tire having two-side fasteners in its tire inner surface in its tire circumferential direction, each two-side fastener including an engagement element group on both sides: covering the engagement element groups on first sides of the two-side fasteners with a protective rubber layer made of an uncured rubber; making a cylindrical first formed body on a making drum, with the two-side fasteners covered with the protective rubber layer being intermittently attached to an inner circumferential surface of the first forming body in a circumferential direction thereof with the engagement element groups on second sides of the two-side fasteners being interposed in between; bonding the first formed body to an inner circumference of an annular second formed body by compression through expanding the first formed body into a toroidal shape, and thereby making the green tire; and curing the green tire inside a mold of a curing machine while pressing the green tire from its inside by a bladder.
    • 本发明提供一种充气轮胎的制造方法,其能够提高在轮胎内表面具有表面紧固件的充气轮胎的生产率,并且避免制造具有劣化的均匀性的充气轮胎,以及防止每个表面紧固件的接合元件 碎。 此外,提供了一种通过充气轮胎制造方法制造的充气轮胎。 根据本发明的充气轮胎制造方法包括以下步骤:在轮胎内周面上形成具有两侧紧固件的生胎,其两侧紧固件包括接合元件组, 用由未固化橡胶制成的保护橡胶层覆盖两侧紧固件的第一侧上的接合元件组; 在制造滚筒上形成圆柱形的第一成形体,其中覆盖有保护橡胶层的两侧紧固件在其周向上间断地附接到第一成形体的内周表面,其中接合元件组在第二侧上 两侧紧固件插在其间; 通过将第一成形体膨胀成环状,通过压缩将第一成形体接合到环状的第二成形体的内周,从而制造生胎; 并在固化机的模具内固化生轮胎,同时通过气囊从其内部挤压生轮胎。

    • A pneumatic tire is provided with a large number of holes that are arranged in the tire's circumferential direction. These holes are provided in land portions that are provided in both shoulder sections of a tread. The land portions can have different pitch lengths. Each of the holes has formed there inside a projection having an upper end with a flat surface or a convex surface. The distance between the outer wall of the projection at the upper end thereof and the inner wall of the hole is set in the range from 1 to 5 mm. The upper end of the projection is located at a position below the opening of the hole.
