<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire for suppressing occurrence of conicity while improving steering stability and flat spot resistance. <P>SOLUTION: Both ends of a carcass layer 6 are folded from the inner side to the outer side around a bead core 4 and a bead filler 5, a flipper layer 7 composed of organic fiber cords is interposed between the bead core 4 and the bead filler 5 on the inner peripheral side, a belt layer 8 and a belt cover layer 9 are arranged on the outer peripheral side of the carcass layer 6 of a tread part 1, and a mounting direction to a vehicle is specified. The height of the bead filler 5 is reduced more on the outer side (Bo) when mounted on the vehicle than the inner side (Bi) when mounted on the vehicle, the height of the flipper layer 7 is increased more on the outer side (Fo) when mounted on the vehicle than the inner side (Fi) when mounted on the vehicle, the maximum height is turned to ≤0.7 times of a tire cross section height SH, and the number of ends of reinforcing cords constituting the belt cover layer 9 is made smaller on the outer side when mounted on the vehicle than on the inner side when mounted on the vehicle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
