Winter Tyre FAQs

Do the speed ratings differ between winter and summer tyres?

Last updated: September 21, 2025

Yes. In general winter tyres have a lower speed rating than summer tyres. This is because of the softer nature of winter tyres, the benefit of which is increased grip in icy or snowy conditions.
 
However, winter tyres shouldn't compromise your driving style as even H rated tyres carry a maximum speed of 131mph, more than enought for most of us. You should however take more care when driving during darker winters with more hazardous conditions.

Winter tyres are specifically engineered with advanced rubber compounds that remain flexible in cold temperatures, typically below 7°C. This flexibility allows the tyre to maintain better contact with the road surface, significantly improving traction and braking performance in challenging winter conditions.

The tread patterns on winter tyres feature deeper grooves and more complex siping (small slits in the tread blocks) compared to summer tyres. These design elements help channel water, slush, and snow away from the contact patch whilst providing additional biting edges for enhanced grip on icy surfaces.

Speed ratings are denoted by letters, with each letter corresponding to a specific maximum speed capability. Common ratings include H (210 km/h), V (240 km/h), W (270 km/h), and Y (300 km/h). The speed rating must meet or exceed your vehicle's requirements.

Whilst you might never drive at these maximum speeds, the speed rating also indicates the tyre's ability to handle heat build-up and maintain structural integrity under various driving conditions, making it an important safety consideration.
