Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 0.89%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre bulge from structural failure 0.66%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Tyre cut reaching ply or cords 0.54%
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 0.27%
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 0.19%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Number plate does not meet standards 0.19%
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 (4.9%) · Tyre slightly damaged or cracking (4.51%) · Brake disc pitted or scored (1.03%) · Nail in tyre, monitor (0.97%) · Tyre worn close to legal limit (0.72%) · Tyre has a shallow cut (0.7%)
