Top failures
Tyre cut reaching ply or cords 0.35%
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 0.35%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre pressure monitoring system faulty 0.28%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Windscreen washer fluid insufficient 0.21%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre tear from structural failure 0.14%
A tear in the tyre's structure means it can fail suddenly, so it must be replaced before the car is driven.
Number plate does not meet standards 0.14%
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 (2.76%) · Tyre slightly damaged or cracking (1.73%) · Nail in tyre, monitor (0.69%) · Tyre has a shallow cut (0.48%) · Brake pads wearing thin (0.28%) · Tyre worn close to legal limit (0.28%)
