What does pneumatic tires mean?

Explanation:
Pneumatic means using air under pressure. Pneumatic tires are tires filled with compressed air to cushion the ride, support the vehicle’s weight, and absorb road shocks. The air acts like a spring, letting the tire deform slightly as you roll, which improves comfort and traction. The other ideas don’t fit because water-filled tires wouldn’t compress properly and would be heavy and impractical; tires with reinforced steel describe the belts or structural materials inside the tire, not the air inside; tires without air would be solid or airless, offering little cushioning. So the best description is tires filled with compressed air.
