Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 2.26%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Coil spring fractured or broken 1.81%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre cut reaching ply or cords 1.76%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre tread below 1.6mm 1.67%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Diesel engine warning light faulty 1.67%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre bulge from structural failure 1.17%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Common advisories
Tyre worn close to legal limit (11.62%) · Brake pads wearing thin (6.06%) · Brake disc pitted or scored (5%) · Tyre slightly damaged or cracking (2.94%) · Wheel bearing slight play (2.9%) · Tyre has a shallow cut (2.75%)
