The invention relates to a preparation method of modified white carbon black tires, which belongs to the technical field of tire preparation. The method is implemented through the steps of preparing a white carbon black by taking sodium silicate and a sulfuric acid as raw materials, modifying the white carbon black by using toluene diisocynate, enabling the obtained object to react with anhydrous butanone, carrying out high-speed centrifugation on the obtained product so as to obtain a precipitate, and drying the precipitate so as to obtain a non-slip additive; putting the non-slip additive, tetrapod-like zinc oxide whiskers and natural rubber into an internal mixer to carry out banbury mixing, so that a tire raw material is obtained; and putting the raw material in a calendar to calendar, so that a modified white carbon black tire is obtained. A tire prepared according to the invention is good in slip resistance and significant in wear resistance; and a modified white carbon black replaces a carbon black as an additive, so that the pollution in the production process is reduced, thereby protecting the human health.
