Standard Tire Pressure for Sedans?

[DiNadia]

The normal standard tire pressure for small cars is between 2.2-2.5 BAR. Here is an introduction about tire pressure: Normal range: The appropriate normal tire pressure is between 2.3~2.7 BAR. However, in summer when temperatures are high, the tire pressure may rise above 3.0 BAR after driving, so a tire pressure value between 2.3~2.5 BAR is more suitable in summer. Excessive tire pressure: This will reduce the friction and adhesion of the tires, affecting braking performance; cause steering wheel vibration and deviation, reducing driving comfort; accelerate wear on the central tread pattern of the tire, shortening tire lifespan; increase vehicle vibration, indirectly affecting the lifespan of other components; when encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and the impact may cause internal cracks and explosions, leading to a blowout. Insufficient tire pressure: This will increase the friction coefficient with the road surface, raising fuel consumption; cause heavy steering and deviation, posing risks to driving safety; increase movement in various parts of the tire, leading to abnormal overheating due to excessive rolling; multiply the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength, which may cause a blowout during high-speed driving; insufficient tire pressure will increase tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, fatigue in the cord layer, and cord breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
