How the air in the tire produce a pressure?

Air in a tire produces pressure due to the collision of air molecules with the inner walls of the tire. When the tire is inflated, the air is compressed, causing the molecules to move more rapidly and collide with the walls more frequently. This constant movement and impact create an outward force, resulting in internal pressure that helps maintain the tire's shape and supports the vehicle's weight. Higher pressure also improves traction and handling by enhancing the tire's contact with the road.
