The application of fumed silica in high-performance tires and its wear resistance enhancement effect can be explained from the following aspects:

1. Application of fumed silica in high-performance tires
Fumed silica is a high-tech ultra-fine inorganic new material. Due to its small particle size, large specific surface area, strong surface adsorption, high chemical purity, good dispersion performance and other characteristics, it has been widely used in the manufacture of high-performance tires. Specifically, fumed silica is mainly used as a tire reinforcement agent, especially in the tread rubber of tires, which can simultaneously improve the life of the tire (improve wear resistance) and safety (improve wet skid resistance), and reduce fuel consumption (reduce rolling resistance).

2. The effect of fumed silica on the wear resistance of tires
Improve strength and elongation: Fumed silica can enhance the bond force between molecules, so that the strength, toughness, ductility and other aspects of the tire material are greatly improved. This enhancement effect helps the tire maintain stable performance and reduce wear during long-term, high-load driving.
Improve the surface finish of raw materials: The high fluidity and small size effect of fumed silica make the surface of tire materials more dense and fine, and the friction coefficient becomes smaller, thereby improving the wear resistance of tires.
Reduce rolling resistance: Studies have shown that the use of all-silica tread rubber can reduce rolling resistance by 20% and tread hysteresis by about 50%, thereby saving more than 3% of fuel. This can not only improve the fuel economy of the vehicle, but also reduce the wear of the tire during driving.

3. Summary
The application of fumed silica in high-performance tires significantly improves the wear resistance of tires. By strengthening the bond force between molecules, improving the surface finish of raw materials, and reducing rolling resistance, fumed silica enables tires to maintain stable performance and reduce wear during long-term, high-load driving. In addition, fumed silica can also improve the high temperature resistance of tires, enhance grip, etc., further improving the safety and driving stability of vehicles. However, using too much fumed silica may reduce the elasticity of tires, affect ride comfort, and increase production costs. Therefore, an appropriate amount of fumed silica needs to be used in the tire manufacturing process to achieve its best effect.
