The revolutionary EP200 sets a new benchmark with Ecopia Compound II, a new compound developed through Bridgestone’s new cutting-edge technology, NANO PRO-TECHTM. Improving performance at a molecular level, the nanotechnology spaces carbon molecules with silica, thereby inhibiting heat generation and energy loss, and allowing you to save on fuel. With improved tread design and square shape shoulder, EP200 leads with significantly improved RRC and uncompromised wet performance.
