Cars fail their MOT for any number of reasons, but recent research reveals that the most common cause of failure is something as simple as the condition of a car’s tyres. While the MOT tests for mechanical failures, the most frequent reasons for test failure are issues relating to safety rather than mechanical excellence.
Sub-standard tyres were to blame in 13 percent of the cases of a test certificate being refused. This is the biggest single cause of a test failure, and yet it is one of the simplest things to rectify. Simply by checking and replacing worn tyres before an MOT, motorists can save themselves time, money and inconvenience.
