A solid wheel comprises a wheel rim and a rubber tire. An internal and an external rings are formed between left and right lateral surfaces of the wheel rim. The internal ring's external periphery is provided circularly with a plurality of axially-extended positioning blocks. Each of plural positioning grooves is formed between any two positioning blocks, the internal ring's external periphery, and the external ring's internal periphery and passes axially through the wheel rim. The external ring's axial width is shorter than the internal ring's. Any of the external ring's left and right lateral sides is provided with a plurality of recesses. The rubber tire's internal periphery is integratedly formed on the internal and external rings of the wheel rim. Thereby, the wheel rim can be firmly fixed with the rubber tire so as to prolong the lifetime of the wheel and ensure the driving safety.
