Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 1.69%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.18%
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 1.11%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Headlamp aim set too high 0.34%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre tread below 1.6mm 0.26%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Number plate does not meet standards 0.26%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Common advisories
Tyre worn close to legal limit (3.96%) · Tyre has a shallow cut (1.37%) · Tyre slightly damaged or cracking (1.07%) · Nail in tyre, monitor (0.92%) · Tyre worn close to legal limit (0.83%) · Brake pads wearing thin (0.73%)
