Is It Normal for the Four Tires to Have Different Tire Pressures?

[StJulia]

Generally, a difference in tire pressure within 0.1 bar among the four tires is considered normal. Variations in tire pressure monitoring errors and different vehicle load conditions can temporarily cause differences in tire pressure. Typically, the rear tires have slightly higher pressure than the front tires. If the difference exceeds 0.2 bar, adjustments are necessary to prevent the vehicle from pulling to one side. Below is relevant information: 1. According to the international GBT2978-2008 standard: standard tires should have a pressure of 2.2-2.5 bar, while reinforced tires should have 2.8-2.9 bar. The manufacturer's recommended tire pressure serves as the standard. These recommendations can usually be found in the vehicle's user manual, on the label near the driver's door (B-pillar), in the drawer next to the driver's seat, or on the fuel tank cap. 2. If you notice a significant inconsistency in tire pressure while driving at high speed, pull over as soon as possible. Allow the tires to cool naturally—do not release air or splash cold water on hot tires. Once the tires have cooled, inspect each one individually.
