<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of securing conductive performance while reducing conductive rubber as well as well-displaying steering stability performance and riding comfort performance by suppressing deterioration in rigidity of the tire. <P>SOLUTION: Outside topping rubber 18 on a carcass ply 7 has a portion starting from an outside interface 31 to a winding section 72 formed by non-conductive rubber and a portion starting from the outside interface 31 and reaching a place of contact with a tread annular body 20 formed by conductive rubber with high rigidity. In addition, inside topping rubber 19 has a portion extending from an inside interface 32 outside in the direction of the tire diameter formed of non-conductive rubber and a portion starting from the inside interface 32 and reaching an adjacent place with a rim strip rubber 4 formed by conductive rubber with high rigidity. The outside interface 31 is positioned more on the inside in the tire diameter direction than the inside interface 32, and the conductive rubber of the outside topping rubber 18 is connected to the conductive rubber of the inside topping rubber 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
