Should the tire pressure be the same for front and rear wheels of a sedan?

[StAyla]

Front tire pressure and rear tire pressure can be different, but the difference should not be too large. Tire pressure is a range, not an exact value. In certain specific situations, it is more appropriate for the rear tire pressure to be higher than the front tire pressure. Below is relevant information: 1. For example, when the rear seats are fully occupied by three people and the trunk is also loaded with many items, the rear tire pressure should be higher than the front tire pressure. Higher rear tire pressure can make the car more fuel-efficient, resulting in lower fuel consumption. Additionally, the car can accelerate faster. The principle is: the higher the tire pressure, the smaller the contact area between the tire and the ground; the lower the tire pressure, the larger the contact area. 2. The front wheels are not only the driving wheels but also the steering wheels. If the front tire pressure is higher, the wear on the front tires will increase. Both the front and rear tire pressures must be within the standard range, and the difference should ideally not exceed 0.1bar.
