Top failures
Tyre cut reaching ply or cords 1.15%
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 1.12%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre bulge from structural failure 1.06%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Coil spring fractured or broken 0.71%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 0.65%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre tear from structural failure 0.59%
A tear in the tyre's structure means it can fail suddenly, so it must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (6.74%) · Tyre slightly damaged or cracking (4.3%) · Suspension ball joint slight play (2.06%) · Tyre has a shallow cut (1.65%) · Brake pads wearing thin (1.53%) · Brake disc pitted or scored (1.44%)
