The invention relates to a multiple-air chamber anti-explosion tyre with high-performance one-way valves and belongs to the technical field of tyres. The tyre comprises a tyre body and a plurality of cavities, wherein the cavities comprise air inflation cavities and a plurality of air storage cavities; a first separation layer is arranged between the air inflation cavity and the air storage cavities; the one-way valve is arranged on the first separation layer; a second separation layer is arranged between two adjacent air storage cavities; the one-way valve comprises a valve body, a piston, a pressing cap and a seal layer between the valve body and the pressing cap; the piston and the seal layer of the one-way valve are made of a composite material; and the composite material comprises the following components: 8-20% of polytetrafluoroethylene powder, 0.5-10% of surface modified carbon fiber, 0.5-10% of modified nanometer CaCO3, 0.5-10% of nanometer Si2N4 and the balance of polyetheretherketone powder. The tyre is simple in structure, air pressures of the air cavities are equal, the one-way valves are made of the composite material, the probability of tyre burst of a vehicle is reduced, and the service life of the tyre is prolonged.
