Use of tyre inflation cages

The sudden depressurisation of a tyre can release a large amount of energy as a percussive shock wave. For tyre assemblies that have split wheels or multi-piece rims these components can become projectiles following a sudden depressurisation.

The risk of a tyre burst is particularly high during the first inflation of a tyre after assembly or mounting i.e. components (e.g. the bead) fail to engage properly, or the wheel or rim is not correctly assembled. This initial inflation is often undertaken in a workshop or maintenance area. The percussive shock wave and projectiles generated can damage equipment and be potentially lethal to personnel in the “line of fire”.
