Abstract
A recessed portion is formed in each tire side portion of an agricultural machinery pneumatic tire. Rigidity at the part of each tire side portion where the recessed portion 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 as a point of origin without reducing the internal pressure, enabling the ground contact width of a tread portion to be enlarged. Since there is no need to intentionally reduce the internal pressure in order to reduce the ground contact pressure, bead portions do not tilt over more than necessary, and there is no reduction in the durability of the bead portions.
