- Inspect the tube for damage or deformation before installation.
- Lightly dust the tube with talcum powder before fitting to reduce friction against the tyre casing and prevent pinching.
- Partially inflate the tube just enough to give it shape before seating it inside the tyre — this helps avoid folds or kinks.
- Use plastic tyre levers rather than metal ones when mounting to avoid puncturing the tube.
- Once seated, inflate gradually and check that the tyre bead is evenly seated on both sides of the rim before reaching final pressure.
- Do not over-inflate; refer to your vehicle's recommended tyre pressure for this tyre size.
- Inspect for slow leaks by submerging the inflated tube in water if a puncture is suspected.
- Store unused tubes uninflated in a cool, dry location away from direct sunlight, ozone sources (e.g. electric motors), and petroleum products.
- Avoid contact with oils, fuels, and solvents, which degrade butyl rubber.
