Regularly checking tire pressure, avoiding direct sunlight, and promptly removing foreign objects are the core of bicycle inner tube maintenance. Proper maintenance significantly extends inner tube life and reduces the risk of tire blowouts during riding.
Maintain Proper Tire Pressure: Check tire pressure before each ride to ensure it is within the recommended range marked on the tire sidewall (usually 30-120 psi, depending on the model). Overinflation can easily lead to a blowout, while underinflation increases the risk of punctures.
Avoid Prolonged Sun Exposure: Ultraviolet rays accelerate rubber aging, causing the inner tube to become brittle and crack. Park in a shady location whenever possible, avoiding direct sunlight.
Regular Cleaning and Inspection: After riding, check the inside of the outer tire for any sharp objects such as glass shards or wires to prevent punctures to new inner tubes. Also, clean the outer tire surface to reduce the risk of corrosion.
Proper Installation and Removal: Use a tire pry bar when changing inner tubes; avoid using metal tools to prevent damage. When installing, ensure the inner tube is flat and free of folds, and align the valve stem with the rim bore to prevent uneven inflation and breakage.
Long-term storage precautions: If the bicycle will not be ridden for an extended period, inflate the inner tube to 80% of the recommended pressure and store it in a dry, well-ventilated place. Hanging it is best to prevent tire deformation and aging due to pressure.
Promptly identify and repair leaks: If the inner tube is slowly leaking air, immerse it in water to observe the location of air bubbles. Once the puncture is found, repair it with a tire patch. For irreparable damage such as a crack at the valve stem base, it is recommended to replace the inner tube with a new one.
