Top failures
Tyre tread below 1.6mm 1.22%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.6%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre bulge from structural failure 0.27%
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 0.22%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Headlamp aim set too high 0.22%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre pressure monitoring system faulty 0.2%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Common advisories
Tyre worn close to legal limit (6.06%) · Tyre slightly damaged or cracking (4.54%) · Brake disc pitted or scored (1.22%) · Nail in tyre, monitor (1.22%) · Brake pads wearing thin (0.93%) · Tyre worn close to legal limit (0.91%)
