A flat tyre is like the measles for drivers. You’re bound to experience it at least once. A flat occurs when the tyre no longer has the correct tyre pressure, the air escaping naturally – yet slowly over time, or due to a tyre puncture, and you need to change tyres.
They can be stressful, especially if it is late at night. You have to switch on your hazard lights and wait for roadside assistance if you don’t have a spare tyre.
