"Velcro" (tires) - what is it? Winter tires "Velcro": reviews

As a rule, for traveling by car inwinter period drivers use two types of winter tires. These tires are studded or "sticky" (friction type). The first tires are equipped with metal spikes, contributing to safe driving on heavily icy roads. In contrast to the "spike", friction ramps have their own technological features and properties, which will be discussed in more detail in this review.

Winter tires "Velcro", as well as studded, are installed on the car for a ride in the winter season, but at the same time they do not have metal studs. This type of tire is more suitable for snow cover.

At the same time, improved properties of terrainare achieved due to certain tread blocks and the presence in them of special small cuts called lamellae. For the best moment of adhesion to the snow-covered road, the slats are technologically located at a certain angle.

Depending on the pattern and tread placementOn the slope, winter tires are attached to four subtypes. This is a directional and non-directional tread pattern, asymmetrical and symmetrical tread.

Types of tires

Friction ramps are soft, the so-called"Scandinavian type", and hard - "European". One of the main characteristics of tires can be attributed to the speed index. This value is indicated by Latin on the side of the slope and indicates the degree of softness of the rubber used. The softer it is, the longer the stopping distance of the car.

“Nordic Velcro” (tires) - what is it?This product is made of very soft rubber and has a large number of lamels in the tread, which in turn contributes to a good moment of adhesion to the road surface. Often in the manufacture of such rays, the technology of adding silicon grit to the rubber composition is used to increase friction with the ice cover. Often this type of tire has not very high speed index values: Q - 160km, R - 170km, T - 190km. As a rule, the main use of such slopes is typical for regions with snowy winters.

"European Velcro" (tires) - what is it?They are made of more rigid materials and equipped with a smaller number of slats. The tread of such tires has a larger pattern, which increases the stability of the car on asphalt. Basically, their index of speed is: H - 210km, V - 250km. Velcro of this type are intended for use in regions with mild winters, and can be operated as interseasonal.

Velcro (tires) - what is it?

Microporous rubber used in itsmanufacturing, helps to improve the controllability of cars on slippery roads. Under the influence of the mass of the car, the lamellae open in the area of ​​contact with the surface, and the tire sticks to the ice cover.

Technological slots of these slopes work assuckers. The result is a good tire contact with the icy and snowy surface. Machine control becomes more stable and reduced stopping distance. Of great importance is the type of applied tread pattern.

Non directional protector

The technical properties of such a tread do not change depending on which way the wheel rotates.

Simply put, both when moving forward andback - the degree of grip is the same. This tread pattern is the most common, and very often such slopes are equipped with cars coming off the assembly line. Non-directional pattern can be both symmetrical and asymmetrical.

If one side of the tire has a distinctivedrawing from the picture on the opposite side, then this pattern is called asymmetric. The main task of the asymmetry of the tread - water drainage to the outside of the slope. If the pattern on both sides is the same and mirrored, it is symmetrical.

Directional Protector

These velcro tires, reviews of which are oftenonly good ones are excellent for wet roads, because, due to the peculiarity of the pattern, the water comes out evenly from under the slope, without forming a water cushion. When installing this type of rubber, it is necessary to take into account the indicated direction of rotation, usually this indicator is printed on the side of the tire in the form of an arrow. With proper installation, the water will go out from under the wheel to its outer part, and if it is wrong, on the contrary, it will collect at the point of contact of the wheel with the road. As well as the skates with non-directional tread, the directional can also be symmetrical and with asymmetry.

Advantages of friction type products

Like any car device, wheel tires also have their own operational advantages and disadvantages.

The same applies to the studless tires.

Advantages of velcro:

• In the production of tires used a certain rubber composition, which does not change the elasticity, even with a strong decrease in temperature. This has a positive effect during operation.
• Low noise while driving. Rubber goes almost silently even on poor-quality asphalt coating.
• Shows excellent driving performance on snow cover. This is achieved due to the fact that the slopes almost stick to the snow. When this happens the moment of maximum coefficient of friction.
• The tread surface perfectly self-cleaning from snow and dirt. In addition, there is a good removal of water cover of the road, which prevents the formation of a water layer between the wheel and the road.
• Ability to install tires (winter, "Velcro")in advance of the onset of cold weather, as well as their use in an unstable spring period. And this means that they can be successfully operated in the offseason.

disadvantages

Cons "sticky":

• They have a lower coefficient of adhesion on the ice cover and knurled snow than studded slopes.
• It is not recommended to use them as all-season tires due to increased tread wear on hot asphalt. This significantly deteriorates the car’s handling and increases fuel consumption.

Friction Rubber Tips

Установив на автомобиль зимние шины («липучка»), motorists reviews advise to roll in ramps. The running process lasts for about two hundred kilometers. When this occurs, grinding the blades, respectively, the road and direction of movement. During this period, and in other respects and in the future, it is categorically not recommended to operate cars with friction ramps in an aggressive driving style. Due to its elastic properties, the velcro protector wears out quickly and can be damaged.

Best tires - "Velcro"

Selection of a set of winter tires - this is a very responsible exercise.

The right tires make driving much easier.cars in the winter and can prevent accidents. At the moment, the tire market has a large assortment in terms of the choice of velcro, with its individual features and characteristics.

Bridgestone Blizzak VRX.Japanese winter tires ("sticky tape"), reviews of which indicate their high cross-country ability in snow-covered areas, are characterized by excellent braking properties and reduced dependence on road gauge. Despite the fact that it is winter tires and the noise level itself can be compared with the summer version of the tire. All this was achieved thanks to modern manufacturing technology and materials used. That is why most drivers buy these tires ("sticky"). The price of the product depends on the size, tread and type. The average cost reaches six thousand rubles.

Continental ContiWinterContact TS850.Another manufacturer, whose products are well proven in our open spaces. Designed specifically for moderate winters, and especially well proved to be in operation on wet roads.

Is the velcro tread symmetry good?Reviews are only positive. With enhanced activity it removes water and melted snow from the point of contact. Due to the large number of tread edges and lamellas, the frictional property of rubber on virtually any surface increases. Silent rolling, economy and quality - this is the Continental card (sticky tires). The average price reaches 4.5 thousand rubles, which is not so much for high quality.

Fulda Kristall Control HP. Rubber from the German manufacturer, specially designed for harsh winter conditions.

Special slats in the center of the ramp enhance momentumsnagging with snow, and the original development of the Snow Catcher is used for natural compression of the slope to ensure tenacious contact. It is not recommended to use such rubber on asphalt pavement and ice, as the noise of the wheel increases. This product is more suitable for movement on roads with constant snow flooring.

Asking about which tires are stickyit is better to use, then it is initially important to consider the nature and geography of the area, the constant climatic conditions and the quality of the roads. But in any case, the operation of such will significantly reduce the likelihood of sticking and the possibility of skidding, increase the braking torque and overall machine handling.

Conclusion

Velcro (tires) - what is it?Based on the review, it is safe to say that this is a very important and necessary type of vehicle equipment, without which driving along winter roads, without getting into an unpleasant situation, is practically impossible.
