Can I drive with a tyre that has a cut or bulge?

nidirect says tyres must be free from certain cuts and defects and correctly inflated.

A bulge can indicate internal structural damage, which is not something to 'watch for a few weeks'. If the tyre may fail, avoid driving at speed or distance and use professional assistance.

Damage on the sidewall is particularly important because many sidewall defects cannot be safely repaired.

For 'Can I drive with a tyre that has a cut or bulge?', treat the issue as a current roadworthiness matter rather than something to leave until the next MOT. A valid MOT does not protect you if the vehicle develops a defect afterwards.

Check the current source for 'Can I drive with a tyre that has a cut or bulge?' before acting if the relevant rule, policy, fee or eligibility has recently changed. Keep any official confirmation or reference number produced by the process because it can help resolve a later query. This note is specific to answer 463.
