Driving on a flat tyre causes permanent damage to the tyre. Reinflating a tyre after you drive on it whilst the tyre is severely underinflated or flat may cause a blowout and a serious crash. Never attempt to reinflate a tyre that has been driven on whilst severely underinflated or flat. In this case, replace the flat tyre as soon as possible.

Changing a tyre can be dangerous. To reduce the risk of serious injury or death, follow the instructions in this section when you change a tyre.
