PURPOSE:To restrain shimmy (vibration around a steering wheel) and chattering (vertical oscillation of wheels) from taking place by forming a cord of a carcass ply of a pneumatic tire by intertwining at least several bandles of organic fiber filaments. CONSTITUTION:A tire 1 for a motorcycle includes a pair of left and right sides walls 2, and a tread 3 in a convex form which is located between the both side walls 2 and 2 and can be elongated to the maximum width of WT. And both the side walls 2 and the tread 3 are reinforced by a carcass 4 where numbers of organic fiber plies are plied so as to allow their cords to intersect each other. In addition, a layer of a breaker is arranged in a crown section which is outside of the carcass 4 to reinforce the crown section. In this case, the cord 8 of the carcass ply is formed by intertwining at least 3 bandles of a number of organic fiber filaments. |
