What is the suitable tire pressure for 19-inch low-profile tires?

[DeLeah]

19-inch low-profile tires generally have a suitable tire pressure range between 2.2-2.5 bar. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car tires, with a slight increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.
