The definition of green tire in Technical Specification for Green Tire is that green tire refers to energy-saving, environmental protection and safety tire products. Green manufacturing concept is practiced in the whole production process and green use is advocated in the application process. Green tires have outstanding dynamic product characteristics, such as low rolling resistance, low fuel consumption, excellent handling stability, shorter braking distance, better wear resistance and multiple retreads. Green tire manufacturing should meet the following overall requirements: the use of environmentally friendly, non-toxic and harmless raw materials in line with the EU REACH environmental standards; the production process to achieve low energy consumption, low noise, low dust, low smoke; products with fuel-saving, safety, high wear resistance, retreadability characteristics, in line with the green tire label certification requirements of rolling resistance. Requirements for grasping and rolling noise of wet pavement.
