PROBLEM TO BE SOLVED: To provide a core type run flat tire capable of running long distances by integrating a tire, a core and a wheel even if the tire is punctured.SOLUTION: A tire 2 as a core type run flat tire 1 has an annular core 3, the tire 2 and the core 3 are attached to a rim 5 of a wheel 4, and a space portion 6 is formed between an inner peripheral portion of the tire 2 and an outer peripheral portion of the core 3. The wheel 4 is composed of an inner wheel 4a and an outer wheel 4b, the core 3 is formed of a solid elastic body, an outer peripheral surface 3a is formed to be convexed to an outside, an inner circumferential surface 3b is formed on a surface along a rim surface 5a of the wheel, and when the inner wheel 4a and the outer wheel 4b are fastened and integrated, a bead portion 2d of the tire and a base portion 3d of the core are pressed between the flange 4c, 4c of the wheel, and the wheel 4, tire 2, and core 3 are integrated.SELECTED DRAWING: Figure 1
【課題】タイヤがパンクしてもタイヤと中子とホイールとの一体化が持続され長距離の走行を可能とした中子型のランフラットタイヤを提供する。【解決手段】タイヤ2の内部に輪状の中子3を有し、ホイール4のリム5にタイヤ2と中子3を装着し、タイヤ2の内周部と中子3の外周部との間に空間部6が形成される中子型のランフラットタイヤ1であって、ホイール4はインナーホイール4aとアウターホイール4bとからなり、中子3は中実の弾性体からなり外周面3aが外側に凸に形成され内周面3bがホイールのリム面5aに沿う面に形成され、インナーホイール4aとアウターホイール4bとを締結して一体化した際に、ホイールのフランジ4c,4c間にタイヤのビード部2dと中子の基部3dとが挟圧され、ホイール4とタイヤ2と中子3とが一体化されてなる。【選択図】図1
