What is the appropriate tire pressure below standard in hot weather?

[NolanRose]

In hot weather, tire pressure should be adjusted to the lower limit of the standard tire pressure for your car. When parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Normal tire pressure reference standards: According to the international GBT2978-2008 standard, standard tires should have a pressure of around 2.4-2.5 bar, while reinforced tires should be around 2.8-2.9 bar. In winter, the standard tire pressure can be slightly increased by about 0.2 bar. When the car is unloaded or half-loaded, adjust the tire pressure to the lower limit of the standard; when fully loaded, adjust it to the upper limit. On rough roads, it is advisable to reduce the tire pressure by 0.1-0.2 bar 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—both excessively low and high tire pressure can affect driving performance and increase tire wear.
