Winter Tyre
A winter tyre uses soft rubber and a deep, siped tread for grip on snow, ice and cold roads.
What is Winter Tyre?
It is marked with the 3PMSF snowflake symbol. Its compound stays flexible below about 7 °C. Some countries require winter tyres in certain conditions. Tread depth matters more in winter; many experts advise at least 4 mm for good snow grip. The M+S mark alone does not guarantee winter performance, while the 3PMSF symbol shows a tested tyre. Speed ratings may be lower than the car's top speed, which is allowed with a dashboard reminder sticker.
How it works
Sipes and grooves bite into snow and channel slush away.
Why it matters for your car
On warm dry roads they wear faster and brake worse. Fit them on all four wheels.
