Abstract: In a carcass (13), between first sections (13A) in which an inter-cord distance between a body portion and turn-back portions gradually decreases outward in a tire radial direction and second sections (13B) in which the inter-cord distance gradually increases, there are disposed first distance-invariant sections (13C) in which the turn-back portions (14B) are brought closer to the body portion (14A) that becomes a substantial bending neutral axis and in which the inter-cord distance is constant, so compressive force acting on the cords of the turn-back portions (14B) can be reduced. By disposing the first distance-invariant sections (13C) between the first sections (13A) and the second sections (13B), the direction of the cords of the turn-back portions (14B) is not suddenly changed, so it becomes difficult for stress to concentrate in the rubber between the cords of the turn-back portions (14B).

Abstract: Improving endurance of bead of radial tire for heavy vehicle. Tire has two beads (2) contacting rim (3) connected by carcass reinforcement (4) having carcass layer (5), with main part (6) wrapped, in each bead (2), axially from inside towards outside of the tire, around bead wire (7) having diameter (L), to form turnup (8) having free end (E). Each bead (2) has filling element (9) with filling compound (10) and extending radially towards outside from bead wire (7) and axially between turnup (8) and main part (6). The distance (I) between turnup (8) and main part (6) decreases continuously from bead wire (7) as far as a first minimum distance (a) reached at a first point (A) of turnup (8), then increases continuously from the first point (A) of turnup (8) as far as a first maximum distance (b) reached at a second point (B) of turnup (8).
