Top failures
Tyre ply or cords exposed 2.11%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.58%
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 1.09%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Suspension ball joint excessively worn 0.91%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Coil spring fractured or broken 0.65%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Ball joint dust cover no longer sealed 0.49%
A damaged dust cover lets dirt into the joint, speeding wear, so the joint may need replacing later.
Common advisories
Tyre worn close to legal limit (10.6%) · Tyre slightly damaged or cracking (5.59%) · Tyre has a shallow cut (2.34%) · Brake disc pitted or scored (1.82%) · Brake pads wearing thin (1.56%) · Tyre worn close to legal limit (1.49%)
