What is the normal tire pressure for front and rear tires of a car?
1 Answers
Car front and rear tire pressures should be consistent. For sedans, the normal tire pressure range is between 2.3 to 2.5 bar. If the car is fully loaded with 5 people, adjusting the tire pressure to around 2.5 bar is more suitable. When there are only two people, a tire pressure of 2.3 bar is also normal. In certain specific situations, it's appropriate for the rear tire pressure to be slightly higher than the front, such as when the rear seats are fully occupied by 3 people and the trunk is heavily loaded. In such cases, the rear tire pressure will naturally be higher than the front. Tire pressure can be affected by various objective factors, including seasonal changes and sun exposure, so minor fluctuations in car tire pressure are generally normal. Both front and rear tire pressures must remain within the standard value range, with an error margin not exceeding 0.1. Different manufacturers may have varying requirements for tire pressure, so the recommended tire pressure values provided by the vehicle manufacturer should always be followed. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are 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 dashboard warning light will turn off, indicating that the tire pressure reset is complete.
