ASSEMBLED BODY OF TIRE AND RIM

PURPOSE:To support the load of a tire when bursting occurs and to prevent a tire from shifting to a side by forming protruded lines on the internal surface of the tire and protrudedly installing a core having a supporting piece on the external peripheral surface of which fitting grooves, which can be protrudingly fitted to the internal surface of a rim. CONSTITUTION:An assembled body 1 comprises a tire T, on the internal surface of which a protrusion 2 is formed and a rim R to the rim body 3 of which a core 5 is fitted. The tire T is fixed to the rim body 3. The core 5 is provided with a supporting piece 7 on the external peripheral surface of which fitting grooves 6 are arranged. To these fitting grooves 6 protruded lines 2 can be fittingly secured. The rim body 3 s provided with a bead seat 21 on which the bead section 13 of the tire T is seated and a flange 22 having a supporting face which receives the outside surface of the bead section 13. When the internal pressure of the tire T is reduced due to bursting, the supporting piece 7 receives the internal surface of the tire T for supporting the load of the tire T. At the same time, the protruded lines 2 and fitting grooves 6 are fitted to each other for preventing the tire T from shifting sideways.
