Provided is a pneumatic radial tire for an agricultural vehicle that is characterized in that: the tire rotation direction is specified, a plurality of lugs are arranged on the tread surface in an alternating manner in the tread circumferential direction between tread width-direction halves, and at least one protruding section is provided on the wall surface of the trailing edge side of the lugs and protrudes from the wall surface in the opposite direction from the specified tire rotation direction, connects with the groove bottom of a groove that defines the lugs, and comprises an upper surface that is orthogonal to the radial direction of the tire; and when a point that is separated from an innermost point (P) in the tread width direction of the wall surface of the trailing edge side of one of the plurality of lugs by 1/3 of the distance of the periphery length of the wall surface of the trailing edge side of the one lug along the periphery is denoted by (Q) and a straight line that connects the point (P) and the point (Q) is denoted by (M), the protruding section of another lug that is adjacent to the one lug on the specified tire rotation direction side and that is positioned on the tread width-direction half that is on the opposite side from the one lug is positioned more to the inner side of the tread width direction than the straight line (M).
