The invention discloses an inflation-free micro bubbling rickshaw tire raw material, an inflation-free micro bubbling rickshaw tire and a preparation method thereof. The tire raw material is preparedfrom narrow molecular weight distribution SSBR, wide distribution powdery PSBR containing isolation agents, regenerated rubber powder, filling rubber oil and auxiliary agents, wherein the auxiliary agents are mainly foaming agents, pigments, accelerators, anti-aging agents, activating agents, crosslinking agents and the like. The raw materials are shaped through extrusion granulation-extrusion injection molding; the prepared inflation-free micro bubbling rickshaw tire has the characteristics that good rebounding performance and weather resistance performance are realized; the intensity is high; the high-temperature deformation is avoided; the low-temperature cracking is avoided; the wear resistance and tearing resistance are realized; the rolling resistance is small; the service life is long, and the like.
