If your van weighs under 3.5 tons, the legal tyre tread limit you must maintain is 1.6mm — just like standard passenger vehicles. This guide explains why tread depth is so crucial for safety, how to check it accurately, and when to replace your tyres to stay compliant and confident on the road.

This is a remarkably easy question to answer, largely because when it comes to vehicle maintenance and tyre tread, the legal limit is consistent across all manner of different road vehicles.

Just like with passenger cars and smaller commercial vehicles, a van that weighs under 3.5 tons is subject to the same legal limit of 1.6mm. 

This means that in order for the van to be classed as legal and safe to drive on roads across the UK and beyond, the tread of the tyre must be 1.6mm deep around the entire circumference and across the full width of the tyre.

Let’s take a closer look at why this matters and how to check…

Why is Tyre Tread So Important?

The tyres of any vehicle form a major part of the vehicle’s maintenance.

Without sufficient tyre tread, tyres do not have enough traction or grip on the road surface. This means that on wet or slipper surfaces, they are more likely to lose grip and cause or be involved in an accident on the road.

And that’s not all.

Tyre tread is also important for displacing water that may be sat on the road surface, forcing the water out of the way rather that skidding over it. In all conditions, sufficient tyre tread plays a major role in braking and the handling of the vehicle, as well as impacting fuel efficiency and even the comfort of both the driver and passengers.

Suffice to say, tyre tread plays a big part in the safety, performance, and comfort of the vehicle - be it a commercial van or a passenger car.

So, how should you check the tyre tread and ensure that it remains above that 1.6mm legal limit?

How to Check Tyre Tread on Your Van

There are several recommended methods for checking the tyre tread on your van – using proper tools or DIY hacks.

  • Use a tyre tread gauge, which reads the tread depth and ensures an accurate result
  • Using the 20p method, whereby you slot a 20p coin into the tread. If the rubber covers the border of the coin, then you know you have at least a tread depth of 1.6mm – and so your tyres are still within the legal limit
  • Using the tyre tread marker. Once the marker sits level with the outer edge of the rubber tyre, you have reached the 1.6mm limit 

While you can use any of these techniques to check your own tyre tread at home, the most important thing to remember when it comes to safe and legal driving, is the importance of regular maintenance.

When Should You Replace Tyres?

Typically, we advise looking to replace your tyres when they reach a tread of 2mm. 

This provides adequate time to identify and source the best tyres, while ensuring that your van remains both legal and safe to drive on the UK roads.

Here at Tyres.co.uk, we offer an unrivalled selection of different tyres to meet the needs of your van – whether you drive it everyday or on a more sporadic basis.
