This paper selects radial off-the-road(OTR)tiresas the subject of study and evaluate the environmental benefits of the tire refurbishment process.The study reveals that,in the production cycle of radial OTR tires,the major sources of environmental impact are the input of raw materials.If tire refurbishing were conducted at the global average rate of 6.00%,the total environmental impact would be reduced by 4.20%.Conversely,if conducted at the North American rate of 47.00%,the reduction in environmental impact could reach 32.90%.This suggests that integrating used tire recycling processes into the production of radial OTR tires has significant environmental advantages.Given the inadequate attention to tire refurbishment in China,the study further provides pertinent policy recommendations.
