3. Damaged tyres or wheel
A flat tyre caused by a puncture is a very common cause of breaking down – in 2016, it was the most frequent reason for AA call-outs. If an unseen pothole or debris on a road surface damages your tyres or wheels, there’s not much you can do except stop and check for damage.
However, poorly maintained tyres are more likely to have issues. Check your tyres regularly, making sure they have a tread depth of at least 1.6mm and they’re inflated to the right pressure. While you’re about it, look for patterns of wear. An uneven wearing of the tyres could indicate that your wheels aren’t aligned properly.
New cars don’t always come with spare wheels, but if you have one, make sure it’s in the same good condition as the other four, and that your jack and any locking wheel nut keys are stored with it ready to use in an emergency.
