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

As a rule, for driving by car in winter, drivers use two types of winter tires. This tire studded or "Velcro" (friction type). The first tires have in the equipment metal spikes, which contribute to safe driving on heavily icy roads. Unlike the "spike", frictional skates have their 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 driving in the winter season, but do not have thorns made of metal. This type of tire is more suitable for snow cover. At the same time, increased patency properties are achieved due to certain blocks of the tread and the presence in them of special small slits, called lamellas. For the best moment of adhesion to the snow-covered road, the lamellas are technologically located at a certain angle.

Depending on the pattern and placement of the tread on the ramp, the winter tires "Velcro" are divided into four subtypes. This is a directional and non-directional tread pattern, an asymmetrical and symmetrical tread.

Types of tires

Frictional rays are soft, so-called "Scandinavian type", and hard - "European". One of the main characteristics of the tire is the speed index. This value is indicated by Latin on the side of the ramp and indicates the degree of softness of the rubber used. The softer it is, the stopping distance of the car will be longer.

"Scandinavian Velcro" (tires) - what is it? This product is made of very soft rubber and has a large number of lamellas in the tread, which in turn contributes to a good grip on the road surface. Often, in the manufacture of such slopes, the technology of adding silicon crumb to the rubber composition is used to increase the 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 application of such skates is typical for regions with snowy winters.

"European Velcro" (tires) - what is it? Made of more rigid materials and equipped with a smaller number of lamellas. The protector of such tires has a larger pattern, which increases the stability of the machine on the asphalt. Basically, the index speed of these is: H - 210km, V - 250km. "Velcro" of this type are intended for use in regions with moderate winters, and can be operated as off-season ones.

Velcro (tires) - what is it?

Microporous rubber, used in its manufacture, improves the controllability of the car on a slippery road. Under the influence of the mass of the car, the lamellas are opened in the area of contact with the surface, and the tire adheres to the ice cover. Technological slots of such skates work as suckers. As a result, a good contact of the tire with the icy and snowy surface is ensured. The control of the machine becomes more stable and the braking distance is reduced . Of great importance is the type of applied tread pattern.

Non-directional protector

The technical properties of such a protector do not change, depending on the direction in which the wheel rotates. Simply put, as with the forward and backward movements, the degree of adhesion to the road is the same. This tread pattern is the most common, and very often such skates are equipped with cars coming off the conveyor. A non-directional pattern can be symmetrical or asymmetric.

If one side of the tire has a distinctive pattern from the figure on the opposite side, then such a pattern is called asymmetric. The main task of the tread asymmetry is to divert water to the outside of the ramp. If the pattern on both sides is the same and is mirrored, it is symmetrical.

Protector of directional type

These "Velcro" tires, reviews of which are often only good, are excellent for a wet road, because due to the pattern of the water, the water evenly leaves 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 marked on the side of the tire in the form of an arrow. With proper installation, the water will escape from under the wheel to its outer part, and with the wrong installation - vice versa, gather at the point of contact of the wheel with the road. As well as rays with non-directional tread, the directions can also be symmetrical and asymmetric.

Advantages of friction type products

Like any car device, the wheel tires also have their operational advantages and disadvantages. The same applies to the tireless tires.

Pros of Velcro:

• In the production of tires used a certain composition of rubber, which does not change the elasticity, even with a strong drop in temperature. This positively affects the operation.
• Low noise during driving. Rubber is almost silent even for poor-quality asphalt.
• Shows excellent driving performance on the snow cover. This is achieved due to the fact that the rajids practically stick to the snow. In this case, the moment of the maximum coefficient of friction occurs.
• The surface of the tread is perfectly self-cleaning from snow and dirt. In addition, there is a good diversion of the water cover of the road, which prevents the formation of a water layer between the wheel and the road.
• The possibility of installing 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 used in the off-season.

disadvantages

The disadvantages of "stickies":

• Have a lower coefficient of adhesion on the ice cover and rolled snow, rather than studded slopes.
• It is not recommended to use them as all-season tires due to increased tread wear on hot asphalt. At the same time, the controllability of the car significantly worsens and fuel consumption is increased.

Tips for operating friction rubber

Installing winter tires on the car ("Velcro"), reviews of motorists advise obkatat rays. The running-in process lasts for about two hundred kilometers. In this case, the lamellas are grinded according to the road and the direction of travel. During this period, and in other and further, it is strictly not recommended to operate a car with friction ramps in an aggressive manner of driving. Due to its elastic properties, the Velcro protector wears out quickly and can be damaged.

The best tires are Velcro

Selection of a set of winter tires is a very important occupation. Properly selected tires greatly facilitate driving in winter and can prevent accidents. At the moment, the market of tires has a wide range in terms of choosing "stickers", with its own individual characteristics and characteristics.

Bridgestone Blizzak VRX. Japanese winter tires ("Velcro"), reviews of which speak of their high cross-country ability on snow-covered areas, are distinguished by excellent braking qualities and decreased dependence on the road gauge. Despite the fact that this winter tires and the noise level 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 purchase data tires ("Velcro"). 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 have proved themselves well in our open spaces. Designed specifically for temperate winters, and especially well shown itself when operating on wet roads. Is the Velcro tread of the "Velcro" tire 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 edges of the tread and lamellas, the frictional property of rubber on almost any surface increases. Quiet rolling, economy and quality is the calling card of "Continental" ("Velcro" tires). The average price reaches 4,5 thousand rubles, which is not so much for high quality.

Fulda Kristall Control HP. Rubber from a German manufacturer, specially designed for severe winter conditions. Special lamellas in the center of the ramp increase the moment of engagement with snow, and the original development of Snow Catcher is used for natural compression of the ramp to provide a tenacious contact. It is not recommended to use such rubber on asphalt and ice, as the noise of the wheel increases. Such a product is more suitable for traveling on roads with constant snow flooring.

Asking about which Velcro tires are best used, it is initially important to consider the nature and geography of the terrain, the constant climatic conditions and the quality of the roads. But in any case, the operation of such will significantly reduce the likelihood of stalling and the possibility of skidding, increase the braking torque and, in general, the controllability of the machine.

Conclusion

Velcro (tires) - what is it? Based on the review, we can say with confidence - this is a very important and necessary type of equipment of the car, without which it is practically impossible to travel on winter roads without getting into an unpleasant situation.
