Frequently Asked Questions

How do I know what tyre size I need?

You can find your tyre size on the sidewall of your current tyres, in your vehicle's manual, or on a sticker inside the driver's side door jamb.

Should I replace all four tyres at once?

While replacing all four is ideal for optimal handling and safety, you can replace them in pairs (both front or both rear) if the other two still have plenty of tread.

What is the legal minimum tyre tread depth?

The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre. However, in the winter we recommend replacing them at 3mm for better safety and performance.

Should i have a wheel alignment with new tyres?

Your tyres can tell us a lot about your vehicle. Uneven wear patterns can indicate alignment or suspension issues, while wear across the tread can reveal whether the tyres have been correctly inflated. They can even give us an insight into your driving habits! By inspecting your tyres, we can often spot potential problems early and help you get the most from both your tyres and your vehicle.

Do i have to have the same size tyres as i do now?

With so many tyre options available, selecting the correct size is crucial for your safety, vehicle performance, and fuel efficiency. Using the wrong size can lead to serious risks and impact how your car handles on the road.

What are the risks of having the incorrect tyre size?

Driving with the wrong tyre size can be dangerous. A tyre that’s too weak to support your car’s weight could burst, increasing the risk of a serious accident. On the other hand, tyres that are too large for your vehicle can reduce stability and raise the chances of rollovers, particularly during sharp turns or emergency manoeuvres. Choosing the right tyre size ensures your car remains safe and responsive in all driving conditions.
