The invention discloses a bending plate type tire device. The bending plate type tire device comprises a wheel rim, wherein a plurality sets of supporting pieces which are continuously bended are fixed on the circumference annular surface of the wheel rim through fastening pieces; a band lining is arranged on the outer parts of the supporting pieces in a padding manner, and is wrapped with a packing piece, or an inflatable cover tire is arranged on the outer part of each of the supporting pieces; the longitudinal section of each supporting piece is in a flat S shape, and each supporting piece is divided into a mounting section, a neck bend, a straight section, a shoulder bend, a working section and a tail section, wherein a tail inserting groove is formed in the surface of the tail end of the working section, and is circular; a jointed part of the tail inserting groove and the tail section of each supporting piece forms a triangular space; a plurality of bosses radially facing outwards are arranged at the position, close to the tail section, of the tail inserting groove. According to the bending plate type tire disclosed by the invention, compared with the prior art, one or more sets of plate-shaped elastic supporting pieces which are mutually connected and continuously bended are mounted on the wheel rim, so that the functions of elastically supporting a wheel load, driving and braking are realized, and the requirement that a vehicle can durably and safely operate in multiple complex and harsh environment is met.
