Top failures
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.
Tyre cut reaching ply or cords 1.27%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 0.56%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre bulge from structural failure 0.56%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Brake pads worn below 1.5mm 0.48%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Number plate does not meet standards 0.4%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Common advisories
Tyre worn close to legal limit (8.05%) · Brake pads wearing thin (3.9%) · Child seat limits belt inspection (1.83%) · Brake discs showing some wear (1.67%) · Tyre worn close to legal limit (1.59%) · Tyre has a shallow cut (1.43%)
