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). |
