Is it illegal to mix winter and summer tyres UK?

When it comes to ensuring road safety, choosing the right tyres for your vehicle is crucial. In the UK, where weather conditions can be unpredictable, many drivers wonder whether it is legal to mix winter and summer tyres. In this article, we will explore the legality of using different types of tyres and provide you with a comprehensive understanding of the regulations surrounding this issue.

Understanding winter and summer tyres

Winter and summer tyres are specifically designed to perform optimally in different weather conditions. Winter tyres are made with a different rubber compound that remains flexible even in low temperatures, allowing the tyre to grip the road better. They also have deeper tread patterns and special siping to improve traction on snow and ice.

On the other hand, summer tyres are constructed with a harder rubber compound that provides better performance in warm weather. They have shallower tread patterns, allowing for better grip on dry roads and improved handling at higher speeds.

The legal requirements

In the UK, there are currently no laws that explicitly prohibit mixing winter and summer tyres. However, it is important to note that using the wrong type of tyre for the prevailing weather conditions can compromise your safety and potentially lead to legal consequences if you are involved in an accident.

Under the Road Traffic Act 1988, drivers have a legal obligation to ensure their vehicle is in a roadworthy condition at all times. This includes having appropriate tyres fitted for the weather conditions. The Act states that tyres must be of the correct type and size for the vehicle and should be in good condition with adequate tread depth.

Considerations when mixing tyre types

Mixing winter and summer tyres on the same vehicle can have adverse effects on handling and performance. The mismatch in grip and traction can lead to unstable driving characteristics, particularly during emergency maneuvers or on slippery surfaces.

Additionally, mixing tyre types may also affect the vehicle’s braking distance, which could be critical in hazardous conditions. Winter tyres are specifically designed to provide maximum stopping power on icy or snowy roads, while summer tyres may struggle to cope with such surfaces.

While it may not be illegal to mix winter and summer tyres, it is strongly recommended to use a set of tyres that are appropriate for the prevailing weather conditions. This not only ensures safety but also maintains the performance and longevity of the tyres.

In conclusion

In the UK, it is not illegal to mix winter and summer tyres on your vehicle. However, it is highly discouraged due to safety concerns. It is always advisable to have a dedicated set of winter tyres for the colder months and switch back to summer tyres when the weather improves.

Remember, road safety should always be a priority, and using the right tyres for the prevailing weather conditions is crucial to ensure the safety of yourself and others on the road.

Can I Drive with Summer Tires in the Winter in the UK?

The Importance of Winter Tires in the UK

In the UK, winter weather conditions can be unpredictable and often include rain, ice, and snow. It is crucial to ensure that your vehicle is equipped with the appropriate tires to handle these challenging road conditions.

Summer Tires vs. Winter Tires

Summer tires, also known as performance tires, are designed to provide excellent grip and handling on dry and wet roads during warmer months. However, they are not suitable for use in winter conditions as their rubber compound hardens in colder temperatures, reducing traction and braking ability.

On the other hand, winter tires are specifically engineered to offer better grip and control on snowy, icy, and wet roads. They have a softer rubber compound that keeps them flexible in low temperatures, allowing for improved traction.

The Legal Requirements

In the UK, there is no legal requirement to have winter tires fitted on your vehicle during the winter season. However, it is highly recommended to switch to winter tires for increased safety and driving confidence on slippery roads.

The Benefits of Winter Tires

Using winter tires in the UK can greatly enhance your driving experience during the colder months. Some key benefits include:

  • Improved Traction: Winter tires have specialized tread patterns and sipes that provide superior grip on snow and ice.
  • Better Braking Performance: The softer rubber compound of winter tires allows for shorter stopping distances, reducing the risk of accidents.
  • Enhanced Handling: Winter tires offer improved control and stability, resulting in better maneuverability on slippery surfaces.
  • Peace of Mind: Investing in winter tires gives you peace of mind knowing that your vehicle is equipped to handle adverse weather conditions.

Considerations for Driving with Summer Tires in Winter

Driving with summer tires in the winter can pose significant risks. Your vehicle’s performance and safety may be compromised due to reduced traction and handling capabilities. It is strongly advised to switch to winter tires when the temperature drops consistently below 7°C.

“Using summer tires in winter can be compared to wearing sandals while walking on ice – it’s just not suitable for the conditions.”


In conclusion, while it is not legally required to drive with winter tires in the UK, it is highly recommended to ensure your vehicle is equipped with them during the winter months. Winter tires offer superior traction, braking performance, and handling in icy, snowy, and wet conditions, providing you with enhanced safety and peace of mind on the road.
