Tire pressure of 20 psi is somewhat low. It should be inflated promptly to maintain a suitable pressure around 2.5-2.7 psi. Both excessively low and high tire pressures can affect the tire's service life. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly impacting the lifespan of other components; Overextends tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire deformation, making the sidewalls prone to cracks and generating flexing movements that cause excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
