PURPOSE: An agricultural tire is provided to easily discharge out soil in a void in the reverse movements of the tire without largely reducing soil-discharging performance and gripping capacity. CONSTITUTION: An agricultural tire is composed of a tread, a side wall, a bead unit, a plurality of lug bars(10) inclined and protruded on the tread, and auxiliary lug bars(15) installed between the lug bars and inclined in the opposite direction to the inclined direction of the lug bar. The inclination angle of the auxiliary lug bar is 0.8¯1.2 times as mush as the inclination angle of the lug bar, the height is 30¯60% of the lug bar, the width(W1) is 25¯30% of the tread, the thickness is 50¯80% of the lug bar. In addition, the auxiliary lug bar is installed in a void(11) between the lug bars.
