摘要： A run-flat radial tire is provided with a side reinforcement rubber layer that extends in the tire radial direction along an inner face of a carcass and an angled belt layer that is provided at the tire radial direction outer side of the carcass. An overlap length L between a maximum width angled belt layer and the side reinforcement rubber layer satisfies the relationship L>0.14× SH with a tire section height SH. A thickness GD of the side reinforcement rubber layer at a position that is 14% of the tire section height to the tire axial direction inner side from a tire axial direction end portion of the maximum width angled belt layer and a thickness GA of the side reinforcement rubber layer at a maximum width position of the carcass satisfy the relationship GD/GA≧0.3.

摘要： A pneumatic radial tire for aircraft in the present disclosure includes a bead core formed by a pair of cable beads embedded in a respective pair of bead portions, a pair of bead fillers respectively arranged outward in a tire radial direction from the pair of bead cores, and a carcass formed by two or more carcass plies that extend toroidally between the pair of bead cores. In a tire widthwise cross-sectional view, an end of a carcass ply, among the two or more carcass plies, closest to the bead filler in a region inward in a tire width direction from the bead filler is located in a region corresponding to 45° to 90° inward in the tire width direction when 0° is defined as outward in the tire radial direction from a center of the bead core.

摘要： A run-flat tire includes a carcass, a tire side portion and a side reinforcement layer. The carcass bridges between a pair of bead portions. The tire side portion links between a bead portion and a tread portion. A carcass maximum width position of the tire side portion, at which the width of the carcass is at a maximum, is provided at the tire radial direction outer side relative to a position that is at 40% of the tire section height. The side reinforcement layer is provided at the tire width direction inner side of the carcass. A thickness of the side reinforcement layer at the position that is at 40% of the tire section height is not more than 65% of a thickness of the side reinforcement layer at the carcass maximum width position.
