1. Improper tire mounting: If the tire is not properly seated on the rim during installation, it can create a gap between the tire bead and the rim. This gap allows air to escape and cause a leak.
2. Deformed rim: A bend or dent in the rim can deform the rim flange, preventing the tire from sealing properly.
3. Damaged tire bead: If the tire bead is damaged, it can prevent the tire from forming a proper seal against the rim, leading to a leak.
4. Damaged or missing rim valve stem: The rim valve stem is responsible for holding air inside the tire. If the valve stem is damaged or missing, the air will leak out.
5. Corrosion: Over time, the rim and tire bead can corrode, creating a gap that allows air to escape.
6. Defective tire: In rare cases, a manufacturing defect in the tire can cause the tire to leak air around the rim.
To prevent tire leaks around the rim, it is important to ensure that the tire is properly mounted on the rim, and that the rim and tire bead are free from damage or corrosion.
