A wheel assembly for a mobile irrigation system having an elongate boom and a plurality of downwardly extending towers. Each tower connects to a wheel assembly which may include at least one support frame for supporting a tire assembly on opposite sides of the wheels so as to distribute weight from the tower across the tire assembly. The wheel assembly may be adapted to be coupled to a tower. The wheel assembly also includes drive axle which may be rotatably coupled to the tire assembly; and a gear box which may be rotatably coupled to the drive axle and mounted on the axle in such a position that it does not support weight of the tower.
