Top failures
Tyre cut reaching ply or cords 1.63%
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 1.08%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Wiper blade not clearing windscreen 0.89%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Coil spring fractured or broken 0.83%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 0.79%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre bulge from structural failure 0.73%
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 (8.73%) · Brake pads wearing thin (6.56%) · Tyre slightly damaged or cracking (2.12%) · Child seat limits belt inspection (1.85%) · Nail in tyre, monitor (1.8%) · Tyre has a shallow cut (1.75%)
