Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 4.13%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 2.77%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 2.23%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Rigid brake pipe excessively corroded 1.93%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre cut reaching ply or cords 1.87%
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 1.24%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Common advisories
Tyre worn close to legal limit (13.26%) · Brake pipes corroded and greasy (13.06%) · Brake pads wearing thin (6.43%) · Brake disc pitted or scored (6.34%) · Tyre slightly damaged or cracking (3.21%) · Wheel bearing slight play (3.09%)
