<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in maneuvering stability.SOLUTION: In a cross-section of a tire 1, a shortest distance SWH between a line 'a' passing through a tire largest bent portion and parallel to a tire rotational shaft and a line 'f' in contact with a bead toe 20 and parallel to the tire rotational shaft is larger than a height of a folded end E of a carcass 3 and smaller than 0.4 times as large as a tire cross-sectional height H. A line segment connecting an intersection S between the line 'a' and the carcass 3 to a center B of a bead core is SB, a position on the carcass 3 a distance of which from the line 'f' is 0.5 times as large as the cross-sectional height H is W, and a magnitude of the line segment SB is smaller than that of a line segment WB connecting the center B to the position W. An intersection between a line 'g' passing through an end portion of a tread 4 in a width direction and orthogonal to the line 'f' and a line 'l' is P, a line passing through the intersections P and S is 'h', a line orthogonal to the carcass 3 on the folded end E is 'c', a line passing through the center B and parallel to the line 'c' is 'd', a line perpendicular to the line 'd' is 'e', an angle formed between the lines 'e' and 'f' isθ, and an angle formed between the lines 'a' and 'h' isθ, and the angleθis equal to or more thanθ.</p> |
