摘要： A tire includes a bead portion with a bead core having a main bead filler and an auxiliary bead filler, and a carcass ply wrapped around a portion of the main bead filler. An end of the carcass ply is located axially outside the main bead filler and radially below an apex of the main bead filler. The auxiliary bead filler is located axially outside the carcass ply end, with an apex of the auxiliary bead filler being located above an apex of the main bead filler.

摘要： It is an object to further improve the durability of bead portions in a pneumatic tire in which a carcass ply is turned up around bead cores. 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) and the cords of the body portion (14A) at the time of collapsing deformation of bead portions 12, and the durability of the bead portions (12) further improves.

摘要： A tire includes a circumferential tread, a pair of sidewalls, and a pair of bead portions. Each bead portion includes a bead and a bead filler. The tire further includes at least one body ply extending from bead portion to bead portion. The body ply includes a pair of turn up portions radially outside of a respective bead portion. An electronic device is embedded in the tire. The electronic device is encapsulated in a curable adhesive including at least one of natural rubber, styrene butadiene rubber, and butadiene rubber.

摘要： A recessed portion (56) is formed in each tire side portion (38) of an agricultural machinery pneumatic tire (10). Rigidity at the part of each tire side portion (38) where the recessed portion (56) is formed is reduced. This enables each tire radial direction outside portion to be made to tilt over toward tire width direction outside with the recessed portion (56) as a point of origin without reducing the internal pressure, enabling the ground contact width of a tread portion (32) to be enlarged. Since there is no need to intentionally reduce the internal pressure in order to reduce the ground contact pressure, bead portions (12) do not tilt over more than necessary, and there is no reduction in the durability of the bead portions (12).
