The invention discloses an irregular rigid ring of a tire. The irregular rigid ring comprises a solid or hollow thin-wall rigid ring which is made of high-strength metal or composite materials and has a certain section shape, and the tire is fixed on a rim by the rigid ring instead of a traditional steel wire ring wound by a copper-plated steel wire; the irregular rigid ring is designed to be of an irregular structure according to the tire structure, tire stress and material distribution; the section shape of the irregular rigid ring is irregular. The irregular rigid ring of the tire has the advantages of having stable shape retention property, simplifying the production flow of the tire, improving the overall rigidity and strength of a tire bead, and improving the fastening force between the tire and the tire bead; the bottom of the irregular rigid ring is designed to be in a shape suitable for a wrapped tire body, so that the poor fitting between the traditional steel wire ring and a tire body cord fabric a
