    • A method of manufacturing a pneumatic tire comprises making a rubber-coated cord-member by coating one or more cords with rubber, and making the tread reinforcement by putting together a plurality of the cord-members around a drum into a cylindrical network of the cords, so that the cords make a first array of cords inclining in one direction with respect to the tire equator and a second array of cords inclining in one direction which is opposite to the cords of the first array with respect to the tire equator. It is possible that the cord-members are woven. It is also possible that the cord-members are not woven and, in the crossings of the cords, one of the two cross cords is curved along the other cord.
    • 一种制造充气轮胎的方法包括通过用橡胶涂覆一根或多根绳索来制造橡胶涂覆的帘线构件,并且通过将多个帘线构件围绕滚筒放置在线的圆柱形网络中而使胎面加强 使得帘线使相对于轮胎赤道在一个方向上倾斜的帘线的第一阵列和相对于轮胎赤道相对于第一阵列的帘线相反的一个方向倾斜的帘线的第二阵列。它是 可能的是帘线构件被编织。 也可能的是,帘线构件不织造,并且在帘线的交叉处,两条交叉线中的一条沿着另一条绳弯曲。

    • A rubber composition containing a specifically limited imidazole compound or imidazoline compound, or benzimidazole or its specifically limited derivative has a large tan .delta. at high temperature range, and a tire having a tread using such rubber composition is prevented from being lowered in the value of tan .delta. due to the temperature rising during the running and has an improved grip performance during the high speed running. The use of Bronsted acid in combination with the imidazole, imidazoline or benzimidazole can obviate the drawback of poor scorch resistance of a rubber composition containing the imidazole, imidazoline or benzimidazole alone, and the resulting rubber composition has a very large tan .delta. at high temperature range, and a tire having a tread using the rubber composition has a remarkably improved grip performance during the high speed running.
    • 含有特别限定的咪唑化合物或咪唑啉化合物或苯并咪唑或其特定限制性衍生物的橡胶组合物在高温范围内具有大的tanδ,并且防止具有使用这种橡胶组合物的胎面的轮胎降低了tan 由于行驶期间的温度上升,并且在高速行驶期间具有改进的抓地性能。 使用布朗斯台德酸与咪唑,咪唑啉或苯并咪唑的组合可以避免单独含有咪唑,咪唑啉或苯并咪唑的橡胶组合物的耐焦烧性差的缺点,并且所得橡胶组合物在高温范围内具有非常大的tanδ 并且具有使用该橡胶组合物的胎面的轮胎在高速行驶期间具有显着提高的抓地性能。
