Legally winter tires are not mandatory, but in an accident it can be expensive for that driver. They also provide more security.

Why winter tires? Ask this question again and again people who live in parts of Germany, where there is hardly snow and ice there, which is nevertheless advised the dealership to buy winter tires. Many avoid the costly investments or assume that they are on their summer tires or all-season tires are making good progress as well. The German Automobile Club (ADAC) does not recommend strongly against it, to give up winter tires.

Adhesion of the tire is reduced at low temperatures

The explanation is simple: The rubber compound of summer tires harden at low temperatures increase. Most experts speak in this context of seven degrees. As a result, the adhesion to the road significantly reduced, which means that the stopping distance may be extended, or even the car to skid. Freezing temperatures in winter are found everywhere in Germany. With winter tires does not happen. They also remain in freezing soft, which is noticeable especially on icy ground. They also have a lamellar profile that dovetailed with loose surfaces such as snow, better.



Winter tires are marked with a snowflake or the M & S symbol (German mud and snow) stands for “Mud and Snow”. This marking is mandatory in Germany, but not protected, so that they can also be placed on non-winter grade tires. Who should have doubt whether it is indeed “real” winter tire should contact his local workshop in conjunction.

The industry is in the manufacture of winter tires in the meantime to the extent that the optical profiles in the winter tires approach the summer tire. Depending on the outside temperature should winter tires as opposed to summer tires with 0.2 to 0.3 are inflated over the bar by the manufacturers value because the tires warm up while driving less and less air pressure rises.

When mounting, ensure that the predetermined rotation direction is maintained. This does not exist in most summer tires. It is also important that the maximum speed indicated by the tire manufacturer is maintained, because otherwise there is a risk that the tread is released from the carcass.

Accident with summer tires

Always comes back to the question of what happens if an accident happens in winter without snow tires. Legally driving is prohibited in winter without winter tires since November 2010 and will be punished with fines for violations. Really expensive it is when a driver gets into an accident. Even if a driver fault not the fault accident, he may be held liable. The insurer does not pay in any case. This risk drivers should therefore be avoided as far as possible, and by October switch to winter tires, because this month the temperatures often approaching the seven-degree mark or less.
