    • A pneumatic tyre for mounting on a normal rim (10), comprising a pair of beads (2) each having a bead bottom surface (2a) seating on a rim seat (12) of the normal rim and bead outer surface (4) connected to the bead bottom surface (2a) and arranged to abut a rim flange (11) of the normal rim, characterised in that the bead outer surface (4) has exhaust means (6) composed of protrusions (6b) extending outwards in the radial direction from an inner end (D) of the exhaust means (6) so as to form an air passage for escaping air from between the rim flange (11) and the bead outer surface (2a) on assembly of the tyre to the rim, and wherein the inner end (D) of the exhaust means (6) is positioned within a region remote from a bead base line by a distance of at least 0.8 and not more than 1.5 times a separating point height Fh defined as the height in the radial direction from the bead base line to a separating point (B) at which the bead outer surface (2a) separates from the rim flange (11) and the outer end (E) is spaced from the inner end (D) by a distance of 5 to 15 mm in the radial direction.
    • 一种用于安装在正常轮辋(10)上的充气轮胎,包括一对胎圈(2),每个胎圈具有安置在正常轮辋的轮辋座(12)上的胎圈底表面(2a)和与胎圈外表面(4)连接的胎圈 到胎圈底表面(2a)并且布置成邻接正常轮辋的轮辋凸缘(11),其特征在于胎圈外表面(4)具有由沿径向向外延伸的突起(6b)构成的排气装置(6) 从排气装置(6)的内端(D)开始,从而在轮胎组装到轮辋时形成用于从轮辋凸缘(11)和胎圈外表面(2a)之间逸出空气的空气通道, 并且其中所述排气装置(6)的所述内端(D)位于远离胎圈基线的区域内至少0.8倍且不大于1.5倍的分离点高度Fh的距离,所述分离点高度Fh被定义为 从胎圈基线至胎圈外表面(2a)从轮辋凸缘(11)分离的分离点(B) 并且外端(E)在径向上与内端(D)隔开5至15mm的距离。

    • A pneumatic tyre, which is adapted for a standard wheel rim (J), comprises a tread portion (2), a pair of sidewall portions (3), a pair of bead portions (4), a carcass extending between the bead portions, a rim flange holder (9) disposed on each side of the tyre and protruding axially outwardly so as to overhang a flange (JF) of the standard wheel rim. The rim flange holder (9) has a hooking part (9a) extending radially inwardly on the axially outside of the flange (JF) so as to hook the flange. The radial measurement between the radially outermost point of the flange and the radially innermost point of the hooking part (9a) is at least 2 mm, and the rim flange holder (9) is provided with a slit (12) extending axially inwardly from the axial outer surface of tne rim flange holder.
    • 适用于标准轮缘(J)的充气轮胎包括胎面部分(2),一对侧壁部分(3),一对胎圈部分(4),在胎圈部分之间延伸的胎体, 轮缘凸缘保持器(9),其设置在轮胎的每一侧上并且轴向向外突出,以伸出标准轮缘的凸缘(JF)。 轮辋凸缘保持器(9)具有在凸缘(JF)的轴向外侧上径向向内延伸以钩住凸缘的钩部(9a)。 凸缘的径向最外点与钩部(9a)的径向最内点之间的径向测量为至少2mm,并且轮缘凸缘保持器(9)设置有从该凸缘轴向内向延伸的狭缝(12) 轮缘法兰座的轴向外表面。
