What is the recommended tire pressure for sedans in summer?
1 Answers
In summer, the normal tire pressure for sedans ranges between 2.3 and 2.5. If the car is fully loaded with 5 passengers, it is advisable to adjust the tire pressure to around 2.5; for regular use with two passengers, a tire pressure of 2.3 is considered normal. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance, making tires more susceptible to punctures from sharp objects like nails or glass, which can lead to internal cracks, blowouts, or tire bursts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing safety risks; Increases movement in various parts of the tire, leading to abnormal heat generation due to excessive rolling; Weakens the function of cords and rubber, causing delamination, cord breakage, or excessive friction with the rim, resulting in bead damage and abnormal wear; Multiplies friction between the tire and ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength, which can lead to blowouts at high speeds; Increases tire deformation, leading to sidewall cracks, flexing movements, excessive heat, rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and accelerating shoulder wear.
