Difficulty: Very hardBasic Maintenance and Daily Checks

When performing a daily tyre inspection on a standard passenger car, the UK legal minimum requirement dictates that the tread depth must be at least 1.6 mm across the entire edge-to-edge width of the tyre, maintaining this depth continuously around the complete circumference.

Answer: Answer

Answer

The statement is False.
The statement is false because the UK Highway Code and vehicle safety regulations mandate a minimum tread depth of 1.6 mm across the central three-quarters of the breadth of the tyre, rather than the entire edge-to-edge width. While the requirement for it to be continuous around the circumference is correct, the width condition renders the claim incorrect.

Step-by-Step Solution

1
Identify the core legal tread depth requirement for car tyres in the UK.
The minimum legal tread depth is mandated at 1.6 mm.
This is the fundamental statutory limit required to ensure adequate grip and water clearance.
2
Determine the required distribution of this tread depth across the tyre's circumference.
The depth must be maintained in a continuous band around the entire circumference of the tyre.
Tyre wear must not dip below the minimum limit at any point around the rotation of the wheel.
3
Identify the statutory requirement regarding the distribution across the width (breadth) of the tyre.
The law applies specifically to the central three-quarters of the breadth of the tread.
The extreme edges of the tyre are not legally required to meet the 1.6 mm limit, acknowledging that vehicle geometry and cornering naturally cause varying wear patterns at the outer margins.
4
Evaluate the provided statement against these exact legal parameters.
The statement incorrectly claims the 1.6 mm limit must apply across the 'entire edge-to-edge width'.
Because the width specification in the statement explicitly contradicts the precise legal definition (central three-quarters), the entire statement is rendered false.
