Top failures
Tyre tread below 1.6mm 2.13%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.43%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Coil spring fractured or broken 1.34%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 1.16%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Brake pads worn below 1.5mm 0.77%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Wiper blade not clearing windscreen 0.64%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Common advisories
Tyre worn close to legal limit (11.52%) · Brake pads wearing thin (7.41%) · Tyre slightly damaged or cracking (4.09%) · Suspension arm pin/bush showing wear (3.93%) · Brake disc pitted or scored (2.6%) · Nail in tyre, monitor (2.17%)
