Performance materials for silica-filled tire tread

Precipitated silica use improves the lab predictors of a passenger car tire tread. Wet traction is predicted to improve by increasing tangent delta @60°C, and rolling resistance by decreasing tangent delta @60°C. To maintain wear resistance, silica should to be dispersed to a similar degree as is carbon black, but also needs to react efficiently with the bifunctional organosilane.
