Abstract: This study analyzes the critical role of aircraft tire performance in ensuring flight safety and stability. Given that the formulation design of natural rubber composites for aircraft tires still heavily relies on long-term empirical accumulation—a process with considerable randomness—this paper proposes, for the first time, the use of China's original grey system analysis and modeling methods to bring scientific rigor to the formulation design and optimization process. The author also outlines a practical and executable workflow for the formulation design and optimization of natural rubber composites for aircraft tires, which can serve as a reference for relevant industries and rubber formulation researchers.
