Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.88%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 1.28%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 1.26%
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 1.05%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Windscreen washer fluid insufficient 0.6%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre bulge from structural failure 0.6%
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 (11.42%) · Brake pads wearing thin (9%) · Tyre slightly damaged or cracking (5.76%) · Brake disc pitted or scored (5.04%) · Nail in tyre, monitor (1.8%) · Tyre has a shallow cut (1.73%)
