Top failures
Tyre cut reaching ply or cords 1.59%
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 0.59%
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 low 0.4%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre ply or cords exposed 0.4%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Headlamp beam pattern obviously incorrect 0.26%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Tyre lump from structural separation 0.26%
A tyre lump means its structure has partly failed and it could burst, so replace it immediately.
Common advisories
Tyre worn close to legal limit (3.77%) · Tyre slightly damaged or cracking (2.31%) · Tyre has a shallow cut (1.39%) · Nail in tyre, monitor (1.19%) · Tyre showing slight damage (0.99%) · Brake pads wearing thin (0.79%)
