摘要： A pneumatic tire 2 includes a tread 4, a pair of sidewalls 6, a pair of beads 8, and a carcass 10. In the pair of beads 8, each bead 8 includes a core 30 and a bead filler 32 extending outward from the core 30 in the radial direction. A minimal value ¸a of the inclination angle of the bead filler 32 is greater than or equal to 30 degrees, and is not greater than 44 degrees. A ratio Wa/Wb of a width Wa of the bead filler 32 to a width Wb of a bead portion is greater than or equal to 0.30, and is not greater than 0.45.

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).

摘要： The joining force between a tire frame member and a bead core (18) is improved. A tire (10) includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections (12) disposed separated from each other along the tire width direction, a pair of side sections (14) that extend from the pair of bead sections (12) toward the tire radial direction outside, and a crown section (16) that connects together the pair of side sections (14); a ring shaped bead core (18) that is embedded in and joined to each of the bead sections (12), and that is formed by a single strand, or plurality of strands, of bead cord (18B) extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; and an extension portion (100) that extends from each of the bead cores (18) in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member.

摘要： In the pneumatic tire of this disclosure, a side reinforcement layer is arranged inside a carcass main body, the side reinforcement layer formed of a treated member, the treated member formed by coating with rubber organic fiber cords extending parallelly to ply cords of a carcass ply of the carcass main body, only on a sidewall portion of a half portion on one tire widthwise side partitioned by a tire equatorial plain; at an unloaded condition, when the pneumatic tire is mounted to an applicable rim and is applied with a prescribed internal pressure, a tire radial inner end of the side reinforcement layer is located on a side inner in the tire radial direction than a tire radial outermost position of a rim flange, and a tire radial outer end of the side reinforcement layer overlaps the belt by 5 mm or more in a tire widthwise direction; and the tread portion has one or more circumferential main grooves extending in a tire circumferential direction, and at an unloaded condition, when the pneumatic tire is mounted to an applicable rim and is applied with a prescribed internal pressure, a contact width of a tire widthwise outermost land portion partitioned by the one or more circumferential main grooves and a tread edge on one tire widthwise side is larger than a contact width of a tire widthwise outermost land portion partitioned by the one or more circumferential main grooves and a tread edge on the other tire widthwise side.
