What Should the Tire Pressure of a Sedan Be?

The normal tire pressure for small cars is generally around 2.3-2.5 bar. This is a recommended value. In actual use, the tire pressure should be determined based on the season and usage environment. Car owners can refer to the vehicle's user manual and the label next to the door, which will detail the manufacturer's recommended value. The tire pressure can be flexibly adjusted according to seasonal temperature changes. When driving in summer, the tire pressure can be appropriately reduced, while in winter, when temperatures are lower, it can be slightly increased. However, when adjusting the tire pressure, it is essential to keep it within the recommended range. 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; Maximum pressure: should not exceed 3.5 bar. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating that the tire pressure reset is complete.
Under normal circumstances, I pay attention to tire pressure during daily driving, which is typically between 30 to 35 PSI, the recommended range for most passenger cars. You can check your vehicle's manual or the label on the door jamb, where the manufacturer's specified pressure is indicated. I find maintaining the correct pressure crucial—it not only improves fuel efficiency but also reduces unnecessary wear. When the pressure is too low, the tire's contact patch increases, leading to higher friction, increased fuel consumption, and sluggish steering. Conversely, if the pressure is too high, ride comfort decreases, handling becomes unstable, especially when driving over rough roads. It's advisable to check the pressure at least once a month to prioritize safety. Additionally, don't forget the impact of temperature changes—tires tend to expand in summer and contract in winter, so leave some margin when adjusting to avoid risks. Regular tire maintenance not only saves money but also ensures peace of mind during travel.
