Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.8%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.02%
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 0.73%
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 0.41%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre bulge from structural failure 0.34%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Coil spring mounting corroded and weakened 0.33%
A rust-weakened spring mounting can let the spring shift or fail, making the suspension unsafe to drive.
Common advisories
Tyre worn close to legal limit (8.89%) · Brake pads wearing thin (4.02%) · Spring mounting corroded, not weakened (2.09%) · Brake disc pitted or scored (2.08%) · Tyre slightly damaged or cracking (1.83%) · Tyre has a shallow cut (1.69%)
