1.6 mm
Under UK law, the legal minimum tread depth for car tyres is 1.6 mm. This depth must be present across the central three-quarters of the breadth of the tyre and around the entire outer circumference.

Step-by-Step Solution

Identify the vehicle category and regulatory context
The vehicle is a standard passenger car governed by UK road vehicle regulations.
Different vehicle categories (such as commercial vehicles or motorcycles) can have different legal standards.

Recall the statutory minimum tread depth limit for cars
The legal threshold is 1.6 mm across the central three-quarters of the tyre's breadth around the entire outer circumference.
Maintaining sufficient tread depth ensures effective water displacement and grip on wet road surfaces.
