Disclosed is a combined tyre, comprising a tyre casing and a core. The tyre casing is an annular member having a core groove around the periphery; the core is an annular member nested within the core groove of the tyre casing in an interference fit, and forms a gap with the inner wall of the core groove of the tyre casing. The combined tyre of the present invention mainly comprises the tyre casing and core, the core being nested within the core groove of the tyre casing, capable of supporting the inner cavity of the tyre casing; therefore, an opening of the core groove of the tyre casing can be large, and in the production process, the model core used for shaping the core groove of the tyre casing can be easily removed, ensuring high production efficiency; in addition, a gap is formed between the core and the inner wall of the core groove of the tyre casing, and the gap can be adjusted as desired and have good cushioning effect; moreover, the tyre casing and the core of the present invention can employ materials of different hardness, offering better comfort. |
