Does low tire pressure mean there is no air?

[Lincoln]

Low tire pressure in a car means that the air pressure inside the tire is insufficient, resulting in underinflated tires. In this case, tire inspection and pressure adjustment are necessary. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, resulting in damage to the tire bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; Increases tire body deformation, making the tire side prone to cracks, and generates flexing motion, leading to excessive heat, rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
