What Is the Legal Tyre Tread Depth for Trucks and Trailers in Europe?

In most European countries, including EU member states, the legal minimum tyre tread depth for trucks, trailers, and heavy goods vehicles (HGVs) over 3.5 tonnes is:

1.6 millimetres

This minimum must be present across the central grooves of the tyre and around the entire circumference.

The 1.6 mm rule applies in countries such as:

• Germany

• France

• Italy

• Spain

• Netherlands

• Belgium

• Poland

• Romania

• And most other EU states

Does the Rule Apply to All Axles?

Yes. The minimum 1.6 mm tread depth applies to:

• Drive axles

• Steering axles

• Trailer axles

• Tag and lift axles

If any tyre falls below 1.6 mm, the vehicle can be declared unroadworthy.

Are There Country-Specific Differences?

While 1.6 mm is the general EU standard, some countries may impose stricter rules during:

• Winter conditions

• Snow and ice seasons

• Mandatory winter tyre periods

For example, certain countries require winter tyres with a minimum of 3–4 mm tread depth during winter months.

Therefore, drivers operating internationally should always check local seasonal requirements.

Penalties for Non-Compliance in Europe

Penalties vary by country but may include:

• On-the-spot fines

• Vehicle immobilisation

• Points on licence (depending on country)

• Additional inspection fees

• Possible transport delays

In some countries, fines can be significantly higher than in the UK.

Is 1.6 mm Enough for Safety?

Although 1.6 mm is the legal minimum, it is considered the absolute limit.

Most fleet operators in Europe replace truck tyres at:

3 mm or more

Reasons include:

• Improved wet grip

• Better braking performance

• Reduced aquaplaning risk

• Increased tyre lifespan planning

• Lower risk during roadside inspections

How to Measure Tread Depth

Professional drivers should use:

• A calibrated tread depth gauge

• Digital measuring tools

• Workshop inspections during scheduled maintenance

Regular tyre checks are essential for cross-border transport compliance.
