Why do winter tyres have lower speed ratings?

Why winter tyres come with lower speed ratings

Winter tyres are made of rubber that allows them to remain flexible and retain some level of grip on surfaces that are below 7°C. However, the soft rubber also keeps tyres from reaching higher speeds.

Does it matter?

Not really. You can fit winter tyres with a lower speed rating in the UK, as long as the winter tyres you are using are designed for cold weather use. Driving at speeds less than the speed rating on the winter tyres is all you need to do.

What you need to know

• Speed ratings are indicated on the sidewall of a tyre. Do not ignore them.
• Some insurance companies may want to know if you have installed winter tyres that have a lower speed rating so do check your insurance policy.
• Switch to summer or all season tyres when the temperature rises above 7°C consistently.
