Silica plays an important role in tire manufacturing. 

- Increase tire wear resistance: White carbon black can fill the gaps in the rubber, increase the density and hardness of the rubber, and make the tire surface harder, thus enhancing its wear resistance.
- Improve the high-temperature resistance of tires: White carbon black has good thermal stability and can absorb heat to prevent tires from aging and deforming at high temperatures, thereby improving the high-temperature resistance of tires.
- Increase tire grip: Silica black can increase the friction coefficient between the tire and the road surface, giving the tire better grip, thereby improving the safety performance of the vehicle.
- Reduce tire rolling resistance: The use of silica can reduce tire rolling resistance, improve vehicle fuel economy, and reduce emissions.
Specifically, in tire tread rubber, the combination of highly dispersible precipitation silica and coupling agents can simultaneously increase tire life, reduce fuel consumption, and effectively improve tire performance. In tire sidewall rubber, white carbon black partially replaces carbon black, which can greatly improve the durability of the rubber compound. In the tread fabrics of passenger and truck tires, silica can maintain the dimensional stability of the compound and improve its resistance to mechanical damage.

For truck tires, the use of silica is intended to improve the puncture and tear resistance of the tread. For off-road tires, the use of silica can reduce heat generation, improve heat resistance and resist chipping and chipping.

In general, silica, with its unique physical and chemical properties, plays an important role in enhancing and improving tire manufacturing, meeting the needs of modern tires for wear resistance, high temperature resistance, grip and fuel economy.
