1. A method for preparing a radial tire with a lignin comprising a step of mixing the lignin in the radial tire; wherein the lignin is a modified lignin prepared by modifying an acetic acid lignin; the modifying is a demethylation or a vulcanization; wherein M100 is 4.9-5.2 MPa, M300 is 18.0-18.9 MPa, a tensile strength of the radial tire at break is 25.6-26.2 TB/MPa, hardness is 79-80 HS.
