The invention relates to a formula and a production technology of a polyurethane low-speed solid tire and belongs to the technical field of high-polymer material products. The formula is characterized by comprising the following raw materials in parts by weight: 0.8-1.5 parts of polyester polyol, 0.15-0.25 parts of toluene diisocyanate, and 0.1-0.15 parts of curing agent component. The production technology is characterized by specifically comprising the following steps: dehydrating the polyester polyol and adding toluene diisocyanate to firstly obtain a prepolymer; and respectively feeding the prepolymer and the curing agent components into tanks A and B of a casting machine, mixing according to the weight parts and casting into a tire casting die, performing casting forming, and performing secondary vulcanization. The integrated solid tire having completely identical internal material, external material and performances is prepared by virtue of the formula technology and the formula, and the technology can be realized by performing primary cast forming through the tire casting die, and the production technology of the tire can be greatly simplified.
