| Abstract: |
| The application of new silane coupling agent NXT instead of silane coupling agent Si69 was studied in the tread compound filled with large amount of silica having high specific surface area for the ultra-high performance tire. The results showed that，with silane coupling agent NXT，the dispersion of silica
in the rubber matrix was effectively improved，the Payne effect of the rubber compound was significantly reduced with increased amount of sulfur，the comprehensive physical properties were improved，the wet skid resistance was significantly improved，the rolling resistance was decreased，and the dry grip performance was reduced. |
