Driving on a flat tyre will cause permanent damage to the tyre. Re-inflating a tyre after it has been driven on whilst severely underinflated or flat may cause a blowout and a serious crash. Never attempt to re-inflate a tyre that has been driven on whilst severely underinflated or flat. In this case, repair or replace the flat tyre as soon as possible.

Changing a tyre can be dangerous. Follow the instructions in this section when changing a tyre to reduce the risk of serious injury or death.
