Top failures
Tyre tread below 1.6mm 1.25%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 0.98%
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 0.82%
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 0.54%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Brake pads worn below 1.5mm 0.54%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre bulge from structural failure 0.54%
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 (9.27%) · Brake pads wearing thin (3.61%) · Brake disc pitted or scored (2.83%) · Suspension arm pin/bush showing wear (2.55%) · Tyre slightly damaged or cracking (1.93%) · Tyre worn close to legal limit (1.71%)
