Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 2.75%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.57%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre bulge from structural failure 1.28%
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 1.08%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Tyre tear from structural failure 0.69%
A tear in the tyre's structure means it can fail suddenly, so it must be replaced before the car is driven.
Diesel engine warning light faulty 0.59%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (6.88%) · Brake pads wearing thin (2.26%) · Tyre slightly damaged or cracking (1.77%) · Tyre has a shallow cut (1.67%) · Propshaft coupling slightly deteriorated (1.47%) · Nail in tyre, monitor (1.38%)
