To challenge Michelin’s Green tire, a new tire tread formulation was developed by means of silanized pre-treated silica nanofiller. The silica surfaces were pre-treated with bis[3-triethoxysilylpropyl]tetrasulfane (TESPT) to chemically bond silica to rubber. With employment of a new novel mixing technique, several SBR/BR (75/25 by mass ratio) blends with different mixing times and mixing temperatures were prepared and cured. Interphase characteristics ( it’s amount and distribution of rubbers in interphase) of all blends along with a wide range of physical and dynamic properties were measured. It emerged that with 50% less filler and 44% less curing chemicals consumption, new developed treads showed absolutely better physical and dynamic properties comparing with Michelin’s Green tire.
