The footprint of an aircraft is defined by which factor?

Explanation:
The footprint on the ground is determined by the surface area that touches the runway, which comes from the tires on the landing gear—the number of tires and their size. More and larger tires increase the contact area, spreading the aircraft’s weight and reducing ground pressure. The other factors—wing span, engine power, and vertical stabilizer height—affect flight characteristics and stability, but they don’t change how much surface touches the ground.
