What is the standard tire pressure for rear car tires?

[OCaroline]

The standard tire pressure for rear car tires is 2.4-2.5bar. There may be slight variations depending on different vehicle models, and specific values can usually be found on the fuel tank cap, the side of the driver's door, or in the user manual. Normal tire pressure reference standards: According to the international GBT2978-2008 standard, the standard tire pressure for regular tires is around 2.4-2.5bar, while reinforced tires require around 2.8-2.9bar. In winter, it is advisable to increase the tire pressure by approximately 0.2bar based on the standard, whereas in summer, the pressure can be slightly reduced by about 0.1bar from the standard to prevent blowouts due to high temperatures. For empty or half-loaded conditions, adjust to the lower limit of the standard tire pressure; for full load, use the upper limit. On rough roads, it is recommended to reduce the tire pressure by 0.1-0.2bar from the standard. Daily tire pressure precautions: Most cars are equipped with a tire pressure monitoring system that alerts drivers to leaks or abnormal tire pressure to ensure driving safety. Pay attention to the tire pressure monitoring light on the dashboard, as both underinflation and overinflation can affect driving performance and accelerate tire wear.
