Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 1.91%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.17%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.17%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Wiper blade not clearing windscreen 1.02%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Dipped beam headlamp not working 1.02%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Headlamp aim set too high 0.86%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (12.12%) · Tyre slightly damaged or cracking (4.41%) · Brake disc pitted or scored (3.63%) · Brake pads wearing thin (2.52%) · Brake discs showing some wear (2.41%) · Tyre worn close to legal limit (2.38%)
