Some vehicles, instead of a standard spare tyre, carry an emergency or temporary-use tyre. In the latter case, in the event of a puncture or blowout, if you have to drive, you must do so respecting the tyre's own limitations (generally emergency tyres have a speed limit of 80 km/h and allow you to travel between 50 and 200 km) and only for the time strictly necessary to take the vehicle to the nearest repair centre.
