    • PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of exhibiting durability performance more than that of the case that steel cords formed of carbon steel with a carbon content exceeding 0.75 wt.% even if steel cords formed of carbon steel with a carbon content smaller than 0.75 wt.% and with superior productivity are applied.SOLUTION: There is provided a pneumatic tire having reinforcement layers with a plurality of steel cords 10 being buried in rubber while being regularly arranged therein where each of the steel cords 10 is formed of a plurality of twisted wires 11, its wire diameter (d) is 0.15 to 0.40 mm, each of the twisted wires 11 is formed of a core segment 11a and a plating layer 11b formed around the core segment 11a, the core segment 11a is formed of carbon steel of which the carbon content is 0.60 to 0.75 wt.%, and on the other hand, an average thickness (t) of the plating layer 11b is in a range of 0.23 to 0.33 μm and the strength of each of the steel cords 10 is in a range of 3,000 to 3,500 MPa.
    • 要解决的问题:提供一种能够比具有碳含量超过0.75重量%的碳钢形成的钢丝帘线的耐久性能更好的充气轮胎,即使由具有碳钢的碳钢形成的钢丝帘线 碳含量小于0.75重量%,并且具有优异的生产率。 解决方案:提供一种具有加强层的充气轮胎,其中多个钢帘线10被埋在橡胶中,同时规则地布置在其中,每根钢丝帘线10由多根绞合线11形成,其线直径 (d)为0.15〜0.40mm,每根绞合线11由芯部11a和形成在芯部11a周围的镀层11b形成,芯部11a由碳含量为0.60的碳钢形成 至0.75重量%,另一方面,镀层11b的平均厚度(t)在0.23〜0.33μm的范围内,钢丝帘线10的强度为3,000〜3,500 兆帕。 版权所有(C)2013,JPO&INPIT
