What is the minimum tread depth required for car tyres

What's the minimum tread depth for your car tyres?

28/11/2017

The legal minimum tread depth for cars is 1.6 millimeters. This 1.6 mm should be in a continuous band throughout the central three-quarters of the tread width, throughout the whole of the circumference.

This rule is applicable for Cars and Light trailers including Caravans weighing up to 3,500 Kgs and/or eight passenger vehicle. This also includes Motorcycles above 50cc, all these vehicles must ensure that the grooves of the tread pattern have a depth of a least 1 mm throughout a continuous band measuring at least three-quarters of the breadth of the tread and round the entire outer circumference of the tyre.

Millimetres not "Millimeters". Manoeuvring, not "Maneuvring". Can you spell check the rest of the Highway Code as it gives the impression that you don't check your facts?

Stop whining, everyone understands what it means.

It is just spelling, it does not invalidate the purpose of it.

1.6 "mm" and "moving about by steering".

I'm with Andy - sloppy spelling reduces confidence in the veracity of the information.

I find the wording on this rule confusing. Is it 1.6mm for motorcycles over 50cc or 1mm?

This is very poorly written, may I suggest.

The minimum tread depth for:
Cars and Light trailers including Caravans weighing up to 3,500 Kgs and/or eight passenger vehicle: 1.6mm in a continuous band throughout the central three-quarters of the tread width, throughout the whole of the circumference.

Motorcycles above 50cc: 1mm across ¾ of the width of the tread pattern and with visible tread on the remaining ¼.

Motorcycles below 50cc: the law requires that all the grooves of the original tread pattern must be clearly visible.

This is attrociously worded yet carries the name of the definitive driving code in the UK and is presumably intended to help UK drivers. Using American spelling on a web site with two UKs in its URL is therefore inappropriate and careless, hopefully unlike the writer's driving. Also, vehicles do not ensure tread depth, their owners do. Avoid this error completely by using the third person: 'tyres must have a depth of...'. More difficult to get wrong!
