Abstract: On the basis of determining the life cycle system of the engineering retread tires, the cost analysis model, the profit analysis model, and the environmental cost-environmental profit analysis model based on the life cycle theory were constructed, and the economic evaluation indicators were put forward. The cost and profit of engineering tires was analyzed and evaluated, in the production stage, transportation stage, use stage and reuse stage (ordinary retread, graphene enhanced retread, mechanical crushing, cryogenic crushing, combustion decomposition and combustion power generation, etc.). The results show that the cost of the engineering tire is the highest in the production stage and the lowest in the transportation stage. The profit-cost ratio of reused engineering tires is the highest using graphene enhanced retread method, followed by ordinary retread method, and the lowest using combustion power generation method.
