These laws are clearly defined by the fuel economy, energy consumption efficiency, and noise in order to increase tire use allowance standards (industrial products must meet the mandatory requirements of each country), and to promote faster development of green products by corporations. Therefore, green products become gradually the mainstream in the industry, and green tires will become the trend of the tire industry. Precipitated silica is an environmentally friendly and high performance additive used in rubber products, textiles, papermaking, pesticides, and as a food additive. Because the rubber used in shoe making, hoses, tapes, and wire and cable making are products of a mature industry, there is limited space for growth in precipitated silica demand in these areas. The other fields except the rubber industry have less demand for the precipitated silica and the need is more diverse. Therefore, the tire market is the greatest potential for precipitated silica in recent years. We have explored tire surface application formulation in environmentally friendly tires with precipitated silica which included high proportion, as well as the sugarcane wax and sugarcane wax plus polyethylene wax to investigate the process ability. Analysis of physical performance showed that adding sugarcane wax to tire surface application formulae for environmentally friendly tires with precipitated silica which included high proportion, improved process ability as well as additive distribution (the Payne effect). The mechanical characteristics also improved without affecting vulcanization and dynamic characteristics. The results of this study can serve as a reference for the production of environmentally friendly tires in the future.
