On July 12, 2025, according to data from the China Association of Automobile Manufacturers, sales of new energy vehicles reached 4.5 million units in the first half of the year, a year-on-year increase of 52%, driving a surge in demand for low rolling resistance tires. Michelin China R&D Center revealed that its latest electric vehicle tires have increased the filling amount of gas-phase white carbon black to 35%, combined with silane coupling agent Si69, reducing the rolling resistance coefficient of the tire to 6.0N/kN (national standard requirement ≤ 6.5N/kN), while achieving A-level wet skid resistance. Black Cat Co., Ltd. has launched nano composite fillers, which mix carbon black with gas-phase white carbon black in a ratio of 3:1, reducing tire weight by 8% while ensuring wear resistance.
