摘要： A pneumatic tire includes an up ply, a down ply, and a cord reinforcing layer. The up ply has: a main body section and a wound section. The down ply is provided on a tire outer surface side of the up ply. The cord reinforcing layer is provided from the inner side to the outer side in the tire axial direction of the bead core to cover the up ply, and has reinforcing cords. A tip of the wound section is located outward in a tire radial direction from a rim flange. An outer end in the tire axial direction of the cord reinforcing layer is located outward in the tire radial direction from a bead upper line and inward in the tire radial direction from the rim flange. The bead upper line extends from an outer surface in the tire radial direction of the bead core.

摘要： A tire comprising two beads, each bead comprising an annular reinforcing structure, a carcass reinforcement, anchored in the two beads by a turn-up around the annular reinforcing structure, so as to form a main portion and a wrapped-around portion. Each bead comprises a bead filler situated at least partially between the main portion and the wrapped-around portion of the carcass reinforcement. Each bead further comprises an outer strip situated axially on the outside of the wrapped-around portion of the carcass reinforcement. The bead filler has a thickness E(r), this thickness corresponding to the length of the intersection of the direction perpendicular to the main portion of the carcass reinforcement with the bead filler, r denoting the distance separating the point of intersection of the direction perpendicular to the main portion of the carcass reinforcement with the carcass reinforcement from the radially innermost point of the annular reinforcing structure. The assembly formed by the bead filler and the outer strip has a thickness ET(r). For all the points of intersection of which the radial distance from the radially innermost point of the annular reinforcing structure is greater than or equal to 10% and less than or equal to 35% of the radial height H of the tire, the ratio E(r)/ET(r) is greater than or equal to 0.3 and less than or equal to 0.5.
