Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 5.62%
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 2.25%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.99%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Wiper blade not clearing windscreen 1.3%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre pressure monitoring system faulty 0.59%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Suspension ball joint excessively worn 0.53%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Common advisories
Tyre worn close to legal limit (17.6%) · Brake pads wearing thin (4.54%) · Brake disc pitted or scored (4.5%) · Tyre worn close to legal limit (2.47%) · Child seat limits belt inspection (2.36%) · Suspension ball joint slight play (2.2%)
