- Before fitting, dust the inside of the tyre and the outside of the tube lightly with talcum powder to prevent the tube from twisting or sticking during installation.
- Partially inflate the tube before inserting it into the tyre to give it shape and reduce the risk of pinching during mounting.
- When seating the tyre bead, work around the rim gradually with tyre levers — avoid levering directly over the tube valve area.
- Once mounted, inflate slowly to a low pressure (approximately 10–15 psi / 0.7–1.0 bar), check that the tube is not pinched or protruding, then inflate to the tyre manufacturer's recommended pressure for your specific tyre and load.
- Do not exceed the maximum pressure stated on the tyre sidewall.
- Inspect the tube for slow leaks by submerging in water or applying soapy water around the valve and bead area if a puncture is suspected.
- Store unused tubes in a cool, dark, dry environment away from ozone sources (electric motors, fluorescent lighting) and petroleum products, which degrade rubber.
- Avoid folding or creasing the tube during storage; coil loosely or store flat.
- Replace the tube if it shows cracking, perishing, significant abrasion, or repeated slow leaks that cannot be reliably repaired.
