PURPOSE:To prevent mud from intruding between tires, by providing a hollow filling material between a pair of right and left tire drums so that the filling material touches the inside of the drum and the sides of a right and left tires, in the double tire for an agricultural machine. CONSTITUTION:A core material 14 is formed by fixing a rubberlike elastic body 15 on the external circumference of the cylindrical core material 14, the core material 14 is held in a pinched state by vertical walls 5a, 11a of a drums 5, 11 to which tires 6, 12 are fixed, an elastic body 15 is made to weld on the inside of walls 5a, 11a of cylinders and the core material 14 is interposed so that the central part is placed between opposed sides of the tires 6, 12. With this constitution, even if mud is about to intrude between the drums 5, 11 from the sides of the tires 6, 12, the intrusion is prevented as a filling material 13 is interposed in a gap between the drums 5, 11. |
