What is the general air pressure for the front and rear tires of a sedan?

Currently, the general air pressure for sedan tires is around 2.3-2.5 bar. Heavier steering wheel: When the friction surface between the tire and the ground increases, the corresponding friction force also increases, making it harder to steer, and the steering wheel becomes heavier. When driving with a flat tire, abnormal noises will occur. Car imbalance: If a tire is flat, it is obvious that the car will tilt to one side. The car's speed will noticeably slow down, and acceleration will be more difficult than usual. When driving with a flat tire, abnormal noises will occur. Tire introduction: The sidewall thickness of a tire is 5mm. Car tires can be divided into pneumatic tires and solid tires based on their carcass structure. Most modern cars use pneumatic tires. Depending on the internal air pressure, pneumatic tires can be classified into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Types of tires: Low-pressure tires are commonly used in various types of cars. Based on their structure, pneumatic tires can be further divided into tube tires and tubeless tires. Sedans generally use tubeless tires. Depending on the arrangement of the internal cord layers and cushion layers, tires can also be classified into radial tires and bias-ply tires. Radial tires are commonly used in cars. The sidewalls of tires are labeled accordingly.
The tire pressure for passenger cars generally falls within a certain range. The front tires are typically between 2.3 to 2.5 bar, while the rear tires are around 2.2 to 2.4 bar. However, this depends on your car model. For example, small city cars may require slightly lower pressure for daily driving, while SUVs might need higher pressure. I make it a habit to check the tire pressure every time I refuel, as underinflated tires wear out faster and are more prone to blowouts, while overinflation can make the ride bumpy and uncomfortable. Using a tire pressure gauge for a quick measurement is most accurate when the tires are cold. Avoid checking right after driving or long trips, as the readings will be higher. Regularly monitoring tire pressure can prevent many unexpected issues. For instance, my last case of uneven tire wear was due to not adjusting the pressure in time. In short, don't just rely on average values; always check the specific recommended pressure on the door frame or fuel cap label.
