Excluding the regulatory exception for certain historic vehicles, for a car’s tyres, what is the legal minimum tread depth in the principal grooves?

Correct answer

1.6 mm.

1.6 mm. Do not drive with less tread depth. Tyres must also be sound: damage, deformation or other defects may require earlier replacement even with sufficient tread. Meeting the minimum does not guarantee equal grip on every surface or replace manufacturer maintenance advice. This case excludes the limited Annex VII.2 exception for certain historic vehicles.
