What is the normal tire pressure for front and rear tires of a car?

[StCamille]

The normal tire pressure for front and rear tires of a car is between 2.3 to 2.5 bar. Dangers of over-inflated tires: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates wear on the central tread pattern, shortening tire lifespan; 4. Increases vehicle vibration, indirectly affecting the lifespan of other components. Dangers of under-inflated tires: 1. Increases friction coefficient with the road surface; 2. Makes the steering wheel heavy and prone to deviation, posing safety risks; 3. Increases movement of tire parts, leading to abnormal heat due to excessive rolling; 4. Weakens the function of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, resulting in tire bead damage and abnormal wear.
