Top failures
Tyre tread below 1.6mm 2.24%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Suspension ball joint excessively worn 1.67%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Tyre ply or cords exposed 1.49%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Diesel engine warning light faulty 1.21%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
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.
Tyre bulge from structural failure 0.72%
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 (11.84%) · Brake pads wearing thin (5.69%) · Suspension ball joint slight play (3.39%) · Brake disc pitted or scored (3.24%) · Brake discs showing some wear (2.55%) · Tyre worn close to legal limit (1.84%)
