Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.33%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.21%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 0.73%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Engine warning light inoperative or lit 0.53%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Tyre bulge from structural failure 0.36%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Number plate does not meet standards 0.28%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Common advisories
Tyre worn close to legal limit (9.39%) · Brake pads wearing thin (3.28%) · Tyre slightly damaged or cracking (2.43%) · Brake disc pitted or scored (2.39%) · Nail in tyre, monitor (1.5%) · Tyre worn close to legal limit (1.46%)
