Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.36%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.16%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Diesel engine warning light faulty 0.89%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 0.75%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre bulge from structural failure 0.49%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Headlamp aim set too low 0.46%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
