Questions
About Winter
Tyre Answered
Most Sweden cars are fitted with summer tyres, and some with all-weather tyres. But winter tyres are designed specifically to give you extra grip in cold temperatures and when driving on snow and ice. The key differences are as follows:
They use a softer rubber compound.The surface of the tread blocks is covered with little jagged slits – called sipes,They generally have deeper tread grooves than a conventional summer tyre.
What are winter tyres?
They are good at gripping cold, damp roads, below about 7C.
Tread grooves and sipes fill up with snow.
Snow gathered in the tread improves grip on loose snow. The key to their improved grip on wet and ice-covered surfaces is the sipes, which provide hundreds of small extra ‘edges’ to grip the road as the tyre rotates.
What are winter tyres good at? The sipes help, not
only because of their edges, but because they enable localized movement of the rubber as the soft compound clings to the road.
A larger single, solid tread block, like the ones you see on summer tyres, would stay rigid in such conditions and be unable to maintain grip as effectively.
No. They are designed for use in all winter conditions - with the tyre manufacturers claiming this means all conditions below 7C.
Are they just for snow and ice?
How much do winter tyres cost?
Ideally, you need a second set of rims to which to fit your winter tyres. In many countries that already use winter tyres, drivers often opt for steel rims, which are less likely to corrode after exposure to winter grit.
They need to be fitted before bad weather strikes. Waiting until the roads are frozen and the car is under a snow drift will mean you’re unlikely to be able to fit them.
In the European countries where the use of winter tyres is mandatory in cold conditions, most people have them fitted around October and then removed (and replaced with summer tyres) around March.
When should I fit winter tyres?
