Top failures
Tyre cut reaching ply or cords 1.09%
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 0.85%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
CV joint boot split or insecure 0.81%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Tyre bulge from structural failure 0.78%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Tyre ply or cords exposed 0.68%
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 0.51%
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 (8.29%) · Brake pads wearing thin (2.52%) · Brake disc pitted or scored (1.47%) · Nail in tyre, monitor (1.47%) · Tyre worn close to legal limit (1.33%) · Child seat limits belt inspection (1.03%)
