Car owners should not be dedicated, hoping to acquire universal winter tires suitable for driving in ice, snow and Rasputice. It is necessary to choose the appropriate tires. Providing reliable adhesion with the track under certain conditions.
It is possible to understand what kind of tread is better for winter rubber, you can familiarize yourself with the characteristics of directional and non-directional, asymmetric and symmetric wheels.
What drawing tread is better for winter rubber
Budget symmetrical rubber noisy when driving in urban conditions, and winter tires Asymmetric is better, as quieter in operation, although they are more expensive. If you need to remove from the contact spot with the roadway, the water is chosen, the directed wheels marked by an arrow informing about how rotation is carried out in which direction. More often for winter buy the following types of tires:
- directional symmetry;
- non-directional asymmetry;
- unfinted symmetry.
Rarely install asymmetric non-directional winter tires, not popular with car owners.
What winter tires are better: symmetrical or asymmetrical
It is impossible to definitely say what kind of drawing is better for winter tires, as it all depends on what condition the road canvas. When the road is deep drifts or highly rambling snow, it is necessary to give preference to directed asymmetric tires that highlight the projector with aggressive design.
If it is supposed to ride on the roads with shallow, pretty lowered snow that is constantly melting, you should choose an infireted projector. When the water is replaced by deep snowdrifts on the road, they establish asymmetric non-directional tires, characterized by side hollows, extending the snow while moving water through drainage channels.
What kind of winter tires is better: directed or non-directional
Choosing which drawing of the Winter Tire Treads is better, it is necessary to understand where it will be used more often vehicle. If the machine will ride the snow cleaned by snow reagent, it is better to buy tires with an asymmetrical low-noise projector. However, having left for the city for not asphalt roads, it is almost impossible to go to them from the snowdrifts.
The best option for the Russian winter can be considered a symmetrical directional pattern, helping to form a course stability and cut off the snow. The truth will have to come to terms with a high level of noise, however, when the permeability is more important, then this is not a problem.
Tire direction
If the car when moving leads to the side and rapidly erase the tires - why can it be?
Made a repeated gathering - collapse, but the problem does not disappear? It may mean that tires are not installed correctly.
Before installing rubber, it is necessary to determine the direction of the tire, because almost every covership is a unique tread pattern, which fully discloses itself, only when the installation is properly installed.
Classification
All automotive tires are divided into the direction of the tire pattern, forming several classifications:
Important: Setting the wheels, it is necessary that all inscriptions "inside" are installed in the direction of the driver!
Definition
Properly determine the direction of rotation of the tire is quite simple - when the car moves forward "Christmas tree (tread pattern)" should be the first to touch the road surface. When stopping, it is necessary that the tread pattern looks in the opposite direction of the side.
The definition method is suitable as summer tiresAnd to winter.
Rotation
Some tires (for example, Bridgestone) can possibly rearrange in places. This is done only the cross - inhibit. This means that it is possible to drive 45-60 thousand kilometers, and then change the location of the wheels. On the place of the right rear it is possible to put the front left, and on the left back - the front right. So you can do with the front wheels, but in a strictly defined order.
If the direction of movement of the tire is set - the wheels are rearranged on one side, i.e. The front tires change to the rear, and vice versa.
When the tires are symmetrical - it is possible to change the location in any order.
Installation
For the installation of asymmetric bridgestone tires, highly qualified skills are required, if you remember several instructions. The inscriptions "Inside", "Outside" must be strictly installed according to the rules.
The directional tires must be installed so that when moving the wheel moved in a specified direction arrow. When installing, it is necessary to focus on move forward.
Symmetric (without direction) Tires are installed at the discretion of the owner. Therefore, there are no guidelines for installation.
IMPORTANT: If at least one wheel is installed incorrectly, then the car control will deteriorate sharply, and the tires will quickly come into disrepair!
The installation is best done as follows:
Competent installation of summer, winter or all-season tires ensures that the tires will reveal their challenges, and car owners will be able to feel comfortable and safe at any time of the year, and on any road covering.
The question "Why did I bring all the four right (or left) asymmetric tires?" Specify with the delivery of tires most attentive car owners.
Reply immediately: "Right", however, as well as the "left" asymmetric tires at the moment is not issued.
A few years ago, Nokian had asymmetric Nokian tires (NRV model), which were "left" and "right." But it turned out that such a decision caused a lot of inconveniences.
First, it complicated and expressed production. Secondly, these inconveniences were connected with the fact that it was often that only left tires remained in one warehouse, and on the other only the right tires. Thirdly, it was not clear to buy spare wheel, After all, no one knows which tire will lower or be in disrepair.
Imagine the situation when you bought 5 tires, two left and three right, it is logical to believe that on the right side and there are more holes and garbage that can damage the tire. By the way, according to statistics, it is the right wheels that suffer more often left. But, by coincidence, it was the left tire that came into disrepair! And having 4 tires of one model (one left and three right), you still can't finish the car with tires.
It is for these reasons that manufacturers now do not produce left and right asymmetric automotive tires.
Then there is a reasonable question, it turns out that asymmetric tiresthat stand on the left, "work" in a different way than to the right?
Yes exactly. When the same asymmetric tires are right on the right, then part of the water is thrown as if - inside back, and if they stand on the left, they emit water inward.
How does all this work and does it prevent this control in the rain? Numerous tests and studies of the largest tire manufacturers have shown that such a tire design does not affect manageability.
Asymmetric tread drawings came to us from motor racing. And they still remain the most effective at high speeds, especially from the point of view of good course stability in turning and informative in the car. It is the asymmetric tires that now conquer the market. automotive tires. They have many advantages over symmetrical and directional tires.
- Excellent car handling, due to the fact that the outer side of the tire (on the bus is indicated - outside), which is much longer loaded in the turn, is made more dense and with larger tread blocks. And the inner, on which the load is much smaller, the opposite is softer. Due to this, it turns out a good tire contact spot with expensive and excellent car handling.
- Universality of the spare wheel. Unlike directed tires, the asymmetric tires do not need to be reinstalled to the disk in the other direction, when the wheel is installed on the right left (or vice versa). After all, the outer side of the asymmetric tire is put on the disk, it will always be outdoor, both when installing the wheel on the left and right.
That is why the asymmetrical tires have become so popular and in demand in despite the fact that the water from the spack of contact is a little differently.
Large companies producing asymmetric tires (such as Michelin, Nokian, Houdier, Continental) spend a huge amount of research by developing and testing various options for tire designs, tread patterns and rubber composition. Therefore, buying tires from well-known manufacturers, they can be safely trusted in this aspect.
The only thing that after in the tire workshop you installed asymmetric tires on the car, it is advisable to check the correctness of their installation.
The inner side on the bus is indicated by Inside, and outdoor outside. Therefore, if you, by all tires (on the sidewalls), you, by the car, see the inscription outside, then everything is installed correctly (inside inside from the outside of the car you should not see).
Some manufacturers of asymmetric tires indicate the outdoor side of the tire (OUTSIDE) as: this side facing outwards, side facing outwards or external. And the inner side of the tire (Inside): this side facing inwards or side facing incards.
Tread - Outdoor element passenger tireswhich is designed to create an optimal contact stain, as well as additional protection against damage and punctures during the ride.
This tire detail varies with a pattern and composition of rubber, each of which is designed for certain weather conditions and the type of road surface. In this article, we will consider the most common types of their.
Figure tread
Tires, depending on their design and applied recesses in the tread canvas, change their characteristics. That is why it is important to know for any conditions and coatings one or another type of tread pattern is intended.
Symmetrical non-directional
One of the most common types of tires for tires. The applied recesses on the outer part of the skate have a mirror reflection, so these tires can be installed on the disk regardless of the side or direction of rotation. Symmetrical unired drawing In addition to the convenience of installation, it has the most balanced characteristics: comfort and smoothness of the course in the first place. There are also such tires cheaper than their complicated fellow.
Symmetrical directional
Such a tread pattern provides the best water removal from the contact spot with an expensive car wheel. Symmetrical directional tires often have high-speed indexes, which allows them to be installed on sports cars. The installation of such tires is carried out on the bus in a specific direction - on the sidewall of the skate there is a "Rotation" inscription, which indicates the direction of rotation of the wheel. Ideal for rainy weather.
Asymmetric non-directional
Tires with such type of tread have excellent driving characteristics - the rebuilding rate on these tires is usually higher in sharp turns and a change of ratings. Also K. sports tires An enhanced sidewall is attached, due to which the noise and comfort with normal ride is reduced. Installation on asymmetric disks estimated tires It is made only in accordance with the labels "Outer" ( outer side disk) and "Inner" ( inner side disk), which are applied on the sidewall of the skate. The drawing combines part of the advantages of a symmetric directional and symmetrical non-directional tire.
Asymmetric directional
The characteristics of such tires are practically identical to a symmetric directional figure, but has a number of advantages - due to the reduced width of the inner side of the tread, the car appears the best adhesion with the road, and the outer part is used to purify the remaining contact spot. Such tires have "Rotation" inscriptions with the direction of rotation, as well as "Inner" and "Outer" to install on the outer or inside of the disk. The price of such skates due to difficulties in their production is usually the highest.
- Symmetrical non-directional - as you like;
- Symmetrical directional in the direction of rotation, the arrow near the "Rotation" inscription;
- Asymmetric infinited on the inscription "Inner" (inner side, closer to the car) or "Outer" (outer side, outside the car);
- Asymmetric directed by "ROTATION" (direction of rotation) and "Inner", "Outer" (installation of the installation on the disk).

Summer tires are designed to operate under the conditions of positive temperatures (above + 5 ° C). Depending on the tread pattern and the type of shape model, they are intended for different road surfaces.
H / T, H / P Highway Tires (Highway Terrain / Performance)
The most common passenger skates, which are intended for use on solid pavement (asphalt, concrete). Such a protector has excellent coupling properties and low level Noise on the above covers. Excellent copes with the removal of water and road dust from the contact stain. Created for the city and trips along the tracks. Do not cope with off-road coatings and are not at all suitable for winter operating conditions.
Universal Tires A / T (All Terrain)
Tires are designed for mixed operating conditions - are equally good for solid coating and roads with mud and gravel. They have a little big noise and less stability than their highways, but the owner of the mud or wet grass will be taken to the cottage or the city. Typically, the drawing on such rods has larger checkers, and the distance between them is more to better clean the contact spot from the dirt.
Mud tires for off-road M / T (MUD terrain)
Such rocks are designed to overcome extreme off-road, stony roads, deep pvov with mud. The protector has a greater height and distance between the sections to be cleaned faster from dirt. In the design, the lateral primortoses are sometimes used (part of the tread is transferred to the sidewall to improve the grip in the dirt and cleansing). Such tires have a high noise level when driving at high speeds, a concrete or asphalt road.
Allowable residual summer tire protector
As wear, part of the tread is abolished and becomes lower, which naturally leads to a deterioration in the characteristics of the tires. Legislative wear is established passenger tires up to 1.6 mm, trucks up to 1.0 mm and motorcycle up to 0.8 mm. In addition, the manufacturer on many tire models provides an internal sideboard located on the protective, which achieved a tire is considered non-operating.
Winter tire tread pattern
Winter tires differ from each other with a tread pattern, as well as the difference in design. You can only split the data of the skates conditionally on three types: "European", "Scandinavian" (they are "arctic") and "Scandinavian" studded.
"European" winter tires
This type of tread is designed for soft winter And practically pure from snow and ice road. The composition of rubber is softer than summer, but tougher than the "arctic" type. They are ideal for wet snow and rain. On the tread there are long diagonal slits, for efficient drainage and usually lateral primers. The tread height is usually up to 8 mm.
"Scandinavian" or "Arctic" winter tires (they are "Velcro")
This tread pattern is designed for harsh winter. Tires are made from soft species Rubber to save properties even in the most rigid frost. The lamellas on the tread canvas are very tightly chopped, the shoulder blocks with an acute edge. The perfect hike for such tires is soft snow with a small glaciation. The height of the tread for new rods is 9-10 mm.
"Scandinavian" or "Arctic" winter tires with spikes
The spikes are usually installed in addition to the velcro that besides an excellent clutch on a snow-covered road gives an advantage on ice. With all this, a huge minus appears - riding on asphalt becomes less comfortable due to increased noise. In addition, on a solid road during braking or harsh accelerations, steel spikes fly out of their seating And you have to spend extra money for their re-installation.
Permissible residual Winter Tire Protector
By rules of traffic rules, on tires intended for use in winter, the protector must be no lower than 5 mm. The manufacturers themselves are recognized that with the height of the tread below 4 mm, almost all coupling characteristics are lost with expensive.
Tread depth
Tire tread cutting
Many auto owners give their tires a chance to the second life, deepening the protector by cutting. There are many disputes around this procedure, read further to find out "Is it possible to cut the protector" and "what is fraught with".
In fact, in the procedure of tread cutting, there is nothing terrible and the manufacturers of tires are allowed, but only on the skates on which it is provided by the structure. Determine whether it is possible to deepen the groove on the tread of your tires just - tire plants Apply the marking "REGROOVABLE" or the letter "U" on the sidewall, which is a resolution to extend the life of the tread. The design of the above skates is specifically added by a rubber layer, which allows you to add recesses on the canvas. If there is no characters on your tire data, then prohibited the procedure is forbidden - this can lead to the destruction of the tire as a result of overheating or too thin height.
How is the cutting of the tread
To cut an extra depth on the protective, it is worth contacting a special service or a tireage that is engaged in this procedure. If you still decide to do it yourself, use the typewriter for cutting the tread for example the RillFit S-146B model. Cost this device Approximately $ 600-700, so it is not entirely beneficial for the disposable procedure.
