What is the ideal tire pressure for the front tires of a sedan?

[Marissa]

The recommended tire pressure for the front tires of a sedan is around 2.3 bar. Under normal circumstances, the front tire pressure is higher than the rear tire pressure because the front of the vehicle houses the engine, while the rear, unless frequently loaded with heavy items, is lighter than the front. This results in higher front tire pressure compared to the rear. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum tire pressure should not exceed 3.5 bar. Hazards of excessive tire pressure: Reduced friction and adhesion of the tires, 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; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks, blowouts, or even tire bursts.
