  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.

Next, conduct a thorough visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, and look for uneven wear patterns that may suggest alignment problems. After this, check for potential leaks by examining the tires and valve stems closely; a simple mixture of soap and water can help reveal leaks through bubbling. If you have adjusted the tire pressures, remember that some vehicles require a manual reset of the tire pressure monitoring system, so consult your owner's manual for specific instructions.
