Every time winter approaches, beforemotorists are the question of preparing for this "slippery" time of the year. Snow drifts on the roads create the danger of emergencies. To maintain the controllability of the car in difficult conditions,
Winter tires with spikes are designed foroperation in the cold season, when snow drifts and ice form on the roads. The greatest efficiency they show at a temperature from -15 to +7 ºС. This circumstance makes the use of such tires the most productive in the climatic conditions of a rough winter with periodic thaws and in the absence of severe frosts. This weather is typical for the middle zone of Russia.
There are two main types: chiseled and stamped. The stud body is usually provided with two or three flanges for fixation and an insert of a hard material. The shape of the product can be different. There is an opinion that the best studded winter tires are equipped with tetrahedral spikes. Such a statement has its justification. The cross-section of the part in this case will be larger than that of the ordinary one, which has a round shape. The total useful area for the whole wheel will increase by one and a half times. However, traditional cylindrical spikes are still popular with drivers because of their lighter weight.
Tires under the soft layer have a layer of hardmaterial. It is used to fasten spikes. Thanks to it, the construction acquires strength and ability to withstand the load. When driving, an additional frictional force occurs. The spiked wheel clings to the surface, ensuring the predictability of the car's movement. Stability on the road depends on the tread of the wheel. For example, studded rubber r17 should have a depth of lines of at least 5 mm, which will give very reliable control over the machine and contributes to its great patency. If we talk about the behavior of such tires when driving on pure asphalt, then there is some inconvenience. It lies in the noise that this rubber produces. The studded surface when rubbing against the road surface produces a sound that annoys many drivers. Also it should be noted that such a ride leads to a rapid wear of the tires. Therefore, in the warm season, they should be changed to summer tires.
The use of all-season tires in winter is not allIt is welcomed, as they cope worse with the snowy tingling and ice. You can also choose the friction tires. The principle of their action is a special tread pattern, containing longitudinal narrow slits - lamellas. Friction rubber, like rubber studded, provides good stability on a slippery road. In any case, give preference to any option should be based on the climatic conditions of its region and taking into account the average temperature in the winter.
