|Doesn’t winter feel uncomfortable? Almost everywhere, the winter season comes up with weather conditions that reduce grip on the road like lower temperatures, more rain and water on the road, light frost or even snow and ice. There’s no escape from this fact, but don’t let it bring you down: winter tires are specially constructed to deal with all of these conditions.|

With adequate equipment, you’re always in a good postition. Because below 7°C winter tires are favorites. Now, water evaporates less and stays longer on the road, making it more slippery. Ground frost can unexpectedly occur, when the ground temperature is lower than air temperature. And if overall temperature drops below 0°C, there might even be ice and snow. Winter tires are adapted to all of these conditions, giving you peace of mind whatever the challenge might be.
Don't let rain thwart your plans. Because even a warm winter is still a particularly rainy season. Ensure that your car will not be floundering as a result of Aquaplaning. When too much water floats the road, water is not dispersed effectively from the tire contact area with the road, causing the tire to float and to lose grip. So counter even stronger rain with winter tires. They are specially designed to derive more water from the tread.
Turn the winter tire to see the grooves
Let’s put the groove design of a summer and a winter tire in competition under bad weather conditions. On which one would you bet? Well in this case, it should be the winter tire. Its weather adapted groove design forms an extra strong drainage system, acting like a water pump. Much more water will be gathered and evacuated from the tread. Bad chance for Aquaplaning.
Excellent drivers are vigilant – be always prepared for ground frost! It can occur unexpectedly, because even if the temperature is above 0°C, ground temperature can be lower. Moisture freezes on the surface, making the road slippery. In this situation, you need tires which are specially constructed for the cold: The compound of winter tires retains resilience and grip even beyond 0°C. So turn on the car heater and enjoy driving pleasure on the beautiful days of winter.
Let’s make a sliding test with a summer and a winter compound. Guess which one stops earlier on a cold surface? Push the compound cubes to see the difference. The winter tire performs better, because the performance features of the summer compound freeze at low temperatures, while the softer compound of the winter tire still develops strong adhesive forces under winter conditions. Braking distance is shorter. You’re better in control.

Don't let snow be a nasty surprise. No matter how much snow you get, it will always be the ultimate test for your tires. Packed snow can be ice-slick and even thawing snow is still very slippery. You might not master the situation if you’re wrongly equipped. Be the one who arrives safely on winter tires. Their tread features sipes, which are missing in summer tires.
Sipes are small transverse incisions in the tread that form grasping edges. They enable the tire to cling to a snowy or slippery surface. That way, they increase braking performance and traction on winter roads.
Look close at your tires: Sipes are the most obvious difference between summer and winter tires. Examine their impact on braking behaviour in the braking test. Choose summer or winter tire and push the brake button. With the winter tire, the car stops much earlier on snow because of its sipes. So snow will no longer keep you away from driving.
