PURPOSE: To enhance the maneuvering stability without increasing the reinforcement of a side wall part by three-dividing the difference in the radial direction heights between the intersections of a carcass line with two straight lines passing two points as specified, and forming each carcass line in the central region in a specified arc shape.
CONSTITUTION: The intersection of a carcass line with a straight line (m) stretching in the tire radial direction while passing the belt width end 44 is represented by A, and the intersection of carcass line with another straight line (n) stretching in the tire width direction while passing the bead core 2 top in the tire radial direction is represented by B. When the difference in the tire radial direction height between the intersections A and B is divided into three segments, at least part of the carcass line corresponding to the central region should form an arc-shaped part 32 having its center of curvature on the outside of the tire while the point of inflection C is interposed. Therefore, the maneuvering stability can be enhanced without increasing the reinforcement of the side wall part.
