A method for retreading a tire with a pre-vulcanic circular tread is provided. A pre-vulcanic circular tread and a base tire, which both have the physical properties of cured rubber, are conglutinated together and vulcanized under increased pressure and ambient temperature which is much lower than 120±5℃. Vulcanization at an ambient temperature can effectively protect the base tire from damaging by the high temperature while ensuring the quality of the retreaded tire. The method includes the following steps: producing a circular tread by a pre-vulcanization process; polishing a crown portion of a base tire and the back surface of circular tread to the same RMA roughness; coating a vulcanized agent uniformly on the surface of crown portion; fitting the circular tread to the peripheral of the base tire coaxially by a radially expanding device; bonding the circular tread and the base tire to form a unitary structure by supplying the pressure of 8-11kg/cm2 between the circular tread and the base tire and keeping at an ambient temperature of 40±5℃ for 45-75 minutes.
