The invention relates to the technical field of highway-railway dual-purpose vehicles, in particular to a highway-railway dual-purpose vehicle driving wheel and a preparation method thereof. By adding the filler in the preparation process of polyamide, stable embedding of the filler is achieved, after compounding of natural latex and stearic acid is combined, under the crosslinking effect of glass fibers, carbon black, white carbon black and nano-zinc oxide are modified, the modified filler good in compatibility with rubber is obtained, the overall performance of a tire is improved, and the service life of the tire is prolonged. And the glass transition temperature is reduced. The method is simple in scheme, high in stability coefficient and good in operability.
