All car tires need to maintain a certain tire pressure, and run-flat tires are no exception. The recommended tire pressure for run-flat tires is similar to that of regular tires, around 2.2-2.5 bar. In winter, the pressure can be increased by 0.2 bar, and in summer, decreased by 0.1 bar. While it’s possible to continue driving if run-flat tires have abnormal pressure, it’s generally not recommended. Both excessively low and high tire pressure can affect normal driving and even create safety hazards. It’s usually best to ensure the tire pressure is normal before driving.
