Why is one tire always low on pressure?

[MaggieDella]

If one tire is always low on pressure, it indicates a slow leak in that tire. This situation requires timely inspection and repair to prevent safety hazards while driving. The standard tire pressure for car tires is generally around 2.5 bar. If the tire pressure is too high, the car may become unstable at high speeds; if the tire pressure is too low, it can affect vehicle handling and increase fuel consumption. Generally, tire pressure can be slightly higher in winter and should be lower in summer. After repairing or replacing a tire, it is essential to perform a four-wheel alignment and dynamic balance. Otherwise, the car may experience abnormal body vibrations at high speeds, significantly increasing safety risks.
