Under UK road traffic regulations, a spare wheel carried inside a passenger car must meet … — UK Driving Theory Test

Under UK road traffic regulations, a spare wheel carried inside a passenger car must meet the statutory minimum tread depth of $1.6\text{ mm}$ while securely stowed in the luggage compartment.

Answer: Answer

Answer

False

The statement is false because UK legislation and MOT testing criteria enforce the statutory minimum tread depth of

1.6\text{ mm}

(across the central three-quarters and around the entire circumference) only on tyres fitted to the road wheels. Drivers are not legally required to carry a spare wheel, and any tyre stowed in the luggage compartment is exempt from minimum tread requirements until it is mounted onto an axle for driving.

Step-by-Step Solution

Identify the legal scope of UK tyre regulations regarding stowed equipment versus active road wheels.

Statutory requirements under the Road Vehicles (Construction and Use) Regulations apply specifically to tyres fitted to the road wheels in active use.

Vehicle safety regulations distinguish between operational components in direct contact with the road and spare equipment carried in storage.

Evaluate MOT inspection criteria and road traffic rules regarding spare tyres.

Carrying a spare tyre is not mandatory in the UK, and an examiner or police officer does not inspect stowed spare wheels for legal tread depth (

1.6\text{ mm}

) or superficial defects.

A spare tyre becomes subject to statutory roadworthiness standards only when it is mounted onto an axle and driven on public roads.

Determine the truth value of the statement.

The statement asserts that a stowed spare must maintain

1.6\text{ mm}

of tread depth while in the luggage compartment, which is legally inaccurate.

The legal threshold applies strictly upon fitment to the vehicle's road hubs.
