It's important for air-filled tires that they need to maintain at least 50 PSI / 3.2 Bar to last long. When tires do not maintain this pressure, they wear out from the inside as the rim displaces the inner tube from its position and it rotates within the tire. It is recommended to check the pressure every other week. The easiest way to do this is with a Xiaomi pump or using a stop valve so that pressure isn’t lost when unscrewing from the valve, unlike with the extenders that are included.
