Tire performance is defined by the magic triangle of rolling resistance, wet grip and tread wear, where enhancement of one property often compromises another due to the viscoelastic behavior of the tread compound. Conventional SSBR/BR-silica-resin systems reduce trade-offs, but simultaneous optimization remains a major challenge. Following Phase 1 ( TTE 2024) and Phase 2 (TTE 2025), this study (Phase 3, 2026) will introduce a compounding approach aimed at extending the magic triangle by tailoring polymer-filler interactions and phase morphology. This seminar provides new directions to achieve preferred tire performance across diverse conditions without deteriorating other critical properties.
