The most affordable price is Cordiant Snow Cross. Fully domestic (and development, and manufacturing) tire upgraded last year. A little more expensive than one more model last season.
Four tires, which in today's standards can be called inexpensive, - Nitto Therma Spike (second brand of the Japanese company Toyo), South Korean Kumho Wintercraft Ice, which is in demand Formula ICE (Development of Pirelli, and the production of Russian) and popular in the Japanese market of Malaysian Assembly »Toyo Observe G3-ICE.
From representatives of the second echelon - new models with German and Finnish pedigree, but produced in Russia: Gislaved Nord Frost 200 with a protector copied with the ContiCecontact first generation, and Nordman 7 with the "face" of the Hakkapeliitta 7 tire.
Finally, the leaders of our past: Goodyear Ultragrip Ice Arctic and Continental Icecontact 2. as well as a hot novelty from Nokian - Model Nokian HakkaPeliitta 9.
Tires in the north
We have already conducted tests outside of Russia and consider this very positive. This time decided to go to the Winter Polygon of Pirelli. It is located in the northern part of Sweden, in the province of Norrbotten, not far from the town of Elvesbün. Ice highways are laid on a frozen lake Lilkish (small Cross swamp), and snowy - on his shores.
In early February there were delivered in advance tires, and at the end of the month we spent all the snow and ice tests. The temperature during the tests ranged from -1 to -15 ºС, however, at first the Swedish north made it hard to revere. On the first day of our work, a warm atmospheric front came on the shores of the Bathroom - and the air temperature rose to the plus of seven degrees! Snow and ice melted in their eyes. Local said that for life, they do not remember such warmth in February. Only on the third day, in the evening, hardening, the lake ice, the lake again succeeded and after a day he was already holding a car. We proceed to the tests on the ice!
Saddle a new hatchback Kia Rio and we specify your own "toolkit". This time, in all exercises, experts are not evaluating not in the entire points, but in the increment in the Polballa - for greater correctness of the results.
On thin ice
First, the assessment of longitudinal coupling properties. Using the VBox device, you will fix the time of overclocking to 30 km / h and immediately after that brake, determining the amount from 30 to 5 km / h. The length of the "tracks" allows you to make four measurements in one direction. Then four more back - and calculated the average value. Basic bus rolling every three test; At the end of the measurements, all the results pass with the way that the results of the "stove" changed.The best overclocking, 6.5 seconds, Rio showed on tires Continental, the second result - on Nokian: 6.8 seconds. No one doubted that tires with 185-186 spikes will turn out to be ahead. However, they compete on heels Cordiant, Goodyear and Nordman, who have 110 spikes - this Trinity shows the result of 6.9 seconds. The most protracted overclocking is Kumho: 9.7 seconds.
In braking, Nokian wins the continental the smallest - 16.4 meters against sixteen and a half, and the third result, 16.7 meters, shows Goodyear. The closure again turned out to be Kumho: 23.7 meters.
Pit in zero
Handling is evaluated on a closed configuration route. This is a "track" length near a kilometer with viyshed of different radius and a long straight. And most importantly - here is very slippery, polished by the wind ice. We spend the assessment together, on each set of tires we go through three circles each, then change.
Heck! Incredibly slippery! To change places, I had to literally transfer on the one hand to another, without taking hands from the car.
The highest score in this exercise deserved Nokian tires: clear reactions and good informative "on the roll" are complemented by a soft, predictable start of slides of the car and a stable clutch regardless of the degree of slippage.
A chute was worse than the Rio, hooping in and nitto. In the first case, liked a good balance of longitudinal and transverse clutch, an understandable moment of transition to slip. The rating was slightly reduced due to low delays in reactions. On Nitto, the car has conquered good handling even in slides and a dense, "clear" steering wheel at large corners of turn. However, there were small claims to the informativeness of the steering wheel at small angles - in the initial phase of the turn. Shinniki refer to this effect Hole in Zero (pit in "zero").
The lowest points marked Gislaved, Goodyear and Formula. On these tires, the driver is forced to increase the angles of rotation of the steering wheel, there are delays in reactions. In addition, Rio on the tires gislaved deblies slides in the turn, and then the grip is restored dramatically, which provokes the effect of the whip - sharp drift in the opposite direction.
Goodyear did not like the imbalance of the longitudinal and transverse clutch: the car holds the arc of the turn much worse than it accelerates and slows down. At Formula - low informativeness "Ruly" in turns that provokes its twisting and subsequent skid.
Ice circle - the most unpleasant exercise for the driver. It is necessary to grope the maximum speed on the verge of slip, show the best time (VBox registers it) and confirm it. At the same time, it falls in one direction, counterclockwise. With a good clutch, the body and head cries the decent lateral strength - constantly strain all the muscles. There is always a look from the "Road" on the devices and back. Circles after fifty begins to spin the head.
Faster than the rest in the circle were Continental and Nokian - 19.9 seconds for a complete turn. Just one tenth (20.0 s) fell behind Cordiant. The most unhurried tires - Kumho: the best achievement is 22.5 seconds.
How many circles had to do on each set to achieve the best results and repeat them? From ten to fifteen! The only tires that demanded more attention and skills - Goodyear: The car shutdown in them all the time tormented to break into the skid, had to cut 19 circles. And total, taking into account repeated races on basic tires, our Rio had to turn more than two hundred turns!
Go to snow procedures
Snow fell exactly the day after completing all ice tests. The route for evaluating manageability is to prepare easier than the plateau for the longitudinal clutch measurements. Therefore, we start with more creative and interesting work.
One vioration of the track lies on the hillside, therefore it has short, but rather steep rise and descent. It is a "chip" of local trails to evaluate manageability - most of the shinniks use mainly flat highways. Rises and descents load and unload the suspension, changing the vertical forces acting on the wheels. It is especially interesting when the wheel is unloaded in the turn: the clamping force decreases, the tire begins to slip.
Fresh snow fell on the cold ice - and shifted when the car slid in turns. As a result, a mixed coating was obtained: Snow places, Ice - real places!
Here in terms of manageability more than others liked Nokian tires: very soft, but confident cat habits, predicted car behavior. Rio on these tires does not require the driver - he just turns. The limit speed is limited to mild, helping to register a turn by a drift that practically does not require adjustments.
Experts presented the greatest claims to the next three of the participants. It annudies unexpectedly occurring drift with a sharp, unpredictable breakdown, long sliding and the same sharp reconstruction of the clutch, which provokes a "shooting" skid in the opposite direction. On the tires gislaved steering wheel becomes unpleasant empty and non-informative - to twist it falls on excessive large angles, which leads to an unexpected sharp breaking into a skid and deep slides. Kumho's tires did not like due to tangible delays in reactions, significant angles of rotation of the steering wheel, protracted slides and deep drift on the arc, requiring an instant adjustment driver.
Exercise "Perealt" due to unnecessary soft snow was performed only partially - they were able to evaluate only the behavior of the machine with extreme maneuvering, and on the determination of the maximum speed of successful execution of the maneuver refused.
Here, as well as on the run of controllability, the largest number of points due to the most clear reactions, soft and predicted behavior and light self-healing drift at the limit speed earned the Nokian tires. Dunlop liked the least: on these tires, Rio show not only tangible delays in reactions, but also an unstable, wide balance of turning: from a significant demolition of the front axle when the steering wheel is first jerked until the rear wheel is dried while trying to stabilize the machine on the rebuilding band.
But the well-drowning snowy straight line - you can do notice the time of acceleration and the brake path. As in similar ice exercises, combine overclocking with braking, repeating the exercises on eight - ten times. Moreover, the time of acceleration from 0 to 40 km / h in the snow was evaluated twice - with the TCS thrust control system and without it. Braking from 40 to 5 km / h - only with ABS.
So, overclocking in normal mode when TCS prevents the tires. The best results are on Tires Continental, Goodyear and Nokian. On them Rio is gaining 40 km / h exactly in six seconds. The worst indicators are at Kumho. As in ice, they accelerate slowly, yielding to the leaders more than 11%.
Turn off the electronic "collar" and repeat measurements. It turns out faster! The leading position holds GoodYear: 40 km / h from the spot are conquered in 5.2 seconds. Only one tenth longer there is overclocking on CONTINENTAL and NOKIAN tires. Kumho tires and in this mode show the most modest result.
Braking wins the leading pair - Continental and Nokian, which showed the same result: 14.8 meters. In closing this time, the relatives of Nitto and Toyo.
The final exercises are an estimate of the course stability on a snow-covered highway and passability in deep snow. At high speed, it is better than others to the specified course and the most clearly rebuilding Rio, waged in Nokian. Additionally, we note the high informativeness of the steering: the driver leads the car in a straight intuitive, not concentrating.
The worst grades are four participants. On the tires Cordiant and Gislaved during the change of traffic, Rio has an unpleasant infringement of the rear axle, turning into a skid. An attempt to adjust the course on Dunlop and Kumho tires is fraught with a drift requiring immediate actions, even with soft rebuilding.
Confidently others in the row of Goodyear tires - Rio is ready to conquer any snowdrift. But on the tires Kumho and Toyo you can go only with a good move. To move in the snow Archis post: the slightest slipboard - and the wheels slip up, driving everything deeper and deeper.
What about spikes?
We were pleasantly surprised. On all tires after running, the spikes performed over the tread in reasonable limits. Maximum, by 1.41 mm, - at the Cordian, the minimum, less than 0.9 mm, - at the Tires Formula, Gislaved and Nokian. That's just Nokian 185 spikes on each tire, and the formula and histoslavd is only 110. And such a quantity is clearly not enough to ensure good clutch on the ice.
Recall that the regulated speech of the spike on new tires is not more than 1.2 mm. According to the experience, we know that after running, this value can increase to 1.3-1.4 mm.
It is gratifying that tire manufacturers have ceased to abuse the magnified speech of "carnations". After all, strongly protruding spikes "saw" asphalt on which deep ruts arise. And for the first time during our tests, no tire has lost a single hips, confirming the postulate that the reliability of retention of spikes in rubber is inversely proportional to the magnitude of their speech. Less sticky - you're tightly!
On asphalt
In Togliatti, at the Polygon AvtoVAZ, we again had to wait for the weather. Dry roads and mouldnoter - conditions for obtaining reliable results on rolling resistance. The asphalt part of the tests were able to fulfill only in the first half of May. It was necessary to work at night to keep the temperature of + 5 ... + 7 ºC permissible for winter tires.
The procedure for estimating the cost effectiveness is the same as in the case of. We start with their warm-up, making a full circle on the speed ring (10 km) at a speed of 110-120 km / h. Along the way, we evaluate how the car deviates from the specified course under the action of external forces (side wind, slope), and also smoothly maneuvering, imitating a soft trailer of the obstacle or shift the band for overtaking. Tester at the same time carefully monitors the reactions and features of the car behavior, and also assesses how convenient and understandable (read: safely) to manage them. The wider "zero" and more angles of turning the ram, which the car does not react, and the lower the informativeness (the rate of increasing efforts on the steering wheel with an increase in the angle of rotation) - the worse the assessment.
The highest assessment for the course stability experts put the Formula ICE tires: the clarity of the course holding and the reactions of the car in them can envy some summer tires! Full opposite - Dunlop tires. The main drawbacks in the behavior of the car on these tires are: wide "zero", an empty steering wheel, delays in reactions when adjusting the course.
After a circle on the ring on a two-kilometer direct, we estimate the magnitude of the ignition from the most allowed "urban" and "country" speeds. Measurements are carried out in opposite directions, repeat from three to five times, depending on the results obtained. At the same time, the driver accumulates the impressions of noise and smoothness at different speeds. The most green, I mean economical, turned out to be the Nokian tires.
Before changing the tires to clarify the assessment of the comfort of Rio makes a circle, moving on service roads with cracks and scherbins. We confessed the tires Gislaved, Toyo and Nitto, and the most soft - Continental and Nokian.
The following exercise is measuring the brake path on the dry surface and on the wet. The initial braking velocities for winter tires are reduced compared to summer 20 km / h - up to 80 km / h on a dry road and up to 60 km / h on wet. Better than others when braking on wet asphalt, the Continental bus looked at the dry - Nokian. The weakest results are NITTO, and independently of the state of the coating, and on dry asphalt, Nitto made up Cordiant.
Summarizing
The winner of the test by typing the greatest number (936) of points, steel new tires Nokian Hakkapeliitta 9.. Second place with the final amount of 914 points occupied Continental Icecontact 2.. We take both tires to the categories of excellent and recommend drivers at all levels.
On the third step of our pedestal - Goodyear Ultragrip Ice Arcticwhich earned 898 final points, the shortage of only two points up to the title of excellent tires. His element - unclean winter roads and even snowy virgin.
At the fourth position with 888 points settled Nordman. seventh generation. Very good tires for the Russian winter will give confidence in any conditions.
All listed tires are located in our rank table in accordance with price rankings. Either they have the price, adequate characteristics and properties, which, in fact, the same thing. And starting from the fifth place, small skews begin in one direction or another.
For example, Cordiant Snow Cross. Earned 871 points, which allowed him to fix it in the category "Very good tires" and take the fifth line of the final result of the test. They do not save on any road, except to comply with the high distance on dry asphalt due to modest coupling properties, and still - slow motion on a snow-covered road. You can buy them at 2500 rubles per piece.
Tires, scored 852 points (sixth place), open the category of good tires. A decent product with average indicators in almost all disciplines. Not without weaknesses, among which are a modest transverse clutch on ice, unimportant term stability on a snow-covered road and asphalt, low level of comfort. But sold for the same money as Cordiant Snow Cross: Price - 2550 rubles.
On the seventh and eighth steps there are even more expensive tires - TOYO OBSERVE G3-ICE and Nitto Therma Spike., Practically brothers and "blood", and properties. They scored 847 points and settled in the "Good Tires" category. Liked a low noise level. The Toyo brand is well known in our market, and Nitto appeared quite recently, therefore a little cheaper.
The ninth and tenth places are divided and, earned at 841 points. These tires still fall into the good category. Gislaved, more even on objective indicators, "failed" in controllability and coursework stability in the snow. The formula has several unbalanced characteristics: it is weak in a longitudinal clutch on ice, but more confidently behaves on the asphalt, close to the best results in braking with a thoughts and ensures a clear retention of the course. But in prices, the difference is tangible: Formula rubles for three hundred cheaper, so a set of four pieces will save more than a thousand. However, there is one technical nuance that combines both tires: Speaking of spikes is insufficient - less than a millimeter after tests. We believe, in the process of installing spikes, a failure occurred.
Seven or eight years ago, in conjunction with Continental investigated and obtained the following pattern: one tenth speakers are equivalent to the three percent of the brake path on the ice. The increase in the speakers of "carnations" to the permissible 1.2 mm on new tires will allow Gislavedov and the formula to improve the longitudinal clutch by about 10% - which is where hidden reserves are hidden!
On the eleventh lines - tires Kumho WinterCraft Ice.who scored 803 points. It is rather weak for modern "riding", but naturally, since in most exercises these tires show modest results. Given the lowest price, it is hardly possible to call them a profitable purchase.
Consider your money
On our diagram, tested tires are built from left to right by increasing prices, and the height of the columns corresponds to the number of scored points. Small columns at the bottom of the chart reflect the ratio of quality and price and show how many points are gaining a tire for each thousand rubles for it.
If you put the price and scrupulously calculate each ruble, pay attention to another column group: the more points for every thousand rubles prices earned the tire, the more profitable! The rating is headed by Tires Cordiant Snow Cross, and the leader of the test HakkaPeliitta 9 turns out to be in the last place - expensive tires! Kumho Wintercraft Ice Tires - in middings, which is why many of them buy them.
Comparing all the results of our test and cen, you can make the right choice. Have a good trip!

NITTO car tire manufacturer is more famous in North America. The fact is that this concern is focused on cars with a powerful engine. First of all, the tires are intended for installation on vehicles with full drive or high-speed sedans. Such a class of cars in Europe is less popular. On the market of the CIS countries about the brand is known little, but some models use just phenomenal demand. This statement is supported by the company's statistics. For example, NITTO THERMA SPIKE Winter Tires often acquire. Reviews of motorists about the presented model in the main mass of positive. On the peculiarities of this rubber and should be reached more detailed.
Purpose
Tires were designed for vehicles equipped with a full drive. They are sold in several dozen sizes with landing diameters from 16 inches to 21. This allows the manufacturer to almost completely cover the corresponding market segment. Rubber winter. The use of special technologies made it possible to achieve a stable clutch with the roadpapers in the most severe temperature conditions of operation. There are disadvantages. The fact is that the compound is not intended to drive to the thaw. The increase in temperature leads to the fact that the rubber becomes a roll, the wear of the tread increases several times. The nature of the tires declare their velocity and load indices. For example, some sizes are able to withstand a mass of up to 925 kg per wheel. Tires for high-speed ride are not intended (most models are not recommended to accelerate more than 190 km / h).
Design
The final owner of the NITTO brand is a large Japanese corporation. Therefore, during design, engineers used the most advanced technologies of this Asian country. First, the constructors created the tire prototype in the form of a digital model. After that, they released several prototypes and conducted their tests at the company's polygon. Such an integrated approach significantly reduced the design cost, allowed us to fully optimize the final technical characteristics. Naturally, it has positively reflected at the speed of work.
Protector features
Many running tires depend directly from the tread pattern. When developing these tires, designers went on a completely unique path. Now winter tires are mostly empowered with a symmetrical directional pattern. Japanese engineers have released Nitto Therma Spike tires with an asymmetrical location of the elements. Such a design method is more characteristic for the summer exploitation, but in this case he still managed to prove his right to exist.
It is also unusual that the brand has departed from the classical construction scheme using several rigid ribs. Winter tires Nitto Therma Spike protector is divided into two zones. External very wide. It consists of massive blocks of complex geometric shape. The dimensions of these elements allow them to maintain their rigidity under various operating conditions. According to Nitto Therma Spike, it is clear that the tires behave perfectly during straight movement, during maneuvering and braking. The car does not lead to the side, riding safe, stable and predictable.
The internal functional area is significantly less. She received a fully open design, as a result of which the water from the contact spot is removed as a short period of time.
Fighting hydroplating
Ride on the puddles is a rather dangerous venture. A micropoline of water is formed between the asphalt cloth and the tread. She prevents them from direct contact with each other. As a result, the car loses the road, begins to slide and vil. Naturally, an accident rises. To minimize the risks, the brand endowed these tires with a special compound and developed drainage system. Reviews of Nitto Therma Spike drivers noted that the tires practically perfect themselves while driving on a wet road.
Under the influence of centrifugal forces, excess water is rapidly delayed deep into the tread. Then its redistribution on the surface and the discoverty to the parties occurs. An increase in the speed of this process contributes to the fully open design of the tread.
The concern was introduced into the rubber mixture of the concern's chemist, the increased share of silicon dioxide was introduced. This compound increases the quality of the clutch with a wet roadpapers. The car perfectly feels the road, promptly responds to any changes in the steering commands.
On ice
Of course, one of the main characteristics of winter tires is their quality clutch with an icy surface. For this indicator, Nitto Therma Spike reviews are only positive. Rubber demonstrates phenomenal reliability, noticeably ahead of more eminent concerns.
First, the distinctive feature is in spikes. NITTO THERMA SPIKE, they have a five-walled shape with a variable cross section. This allows you to ensure the desired clutch quality with the surface at any vectors. The core of elements is made of carbide material. As a result, the reliability of fixation in the protective is increasing, but it should not forget about the need. The driver after installing new rubber should be about 1 thousand km to drive in the most gentle mode. This will allow spikes better to fix in places of attachment and prevent their premature departure.
Secondly, each tread unit is equipped with lamellas. Elements increase the number of cutting faces in the contact stain. This positively affects the final clutch quality.
On snow
During independent tests, Nitto Therma Spike it turned out that the model was effectively moved and on loose snow. Drainage grooves have an increased width. This allows them to quickly remove snow from the contact area.
On asphalt
In this case, the situation is ambiguous. According to Nitto Therma Spike, it is clear that the tires are confidently moving along the asphalt canvase, but sometimes the car loses controllability. Such a tendency is characteristic of all tires equipped with spikes. Access to large speed indicators in this class of rubber is extremely recommended.
Durability
The resource of this NITTO tire model is huge. The manufacturers themselves argue that the tires are capable of overcome more than 85 thousand km of mileage. Such indicators are exceptional. Achievement of the presented characteristics was made possible by the use of a number of innovative solutions.
First, the brand engineers have achieved the perfect distribution of the external load on the contact stain. This makes it possible to eliminate the uneven wear of the tread. Both functional zones (external and internal) are erased at the same speed.
Secondly, the model was given a reinforced frame. Metal wire is reinforced with elastic polymer compounds. The energy occurs when driving around the bumps does not lead to the deformation of the metal, but is distributed and quenched by nylon. As a result, there is no risk of rupture of the frame and the occurrence of hernia. In reviews of Nitto Therma Spike, motorists note that the tires behave perfectly even when they hit in a pothole on the asphalt coating. For many other models, such operation is destructive.
Third, these Nitto tires in the compound obtained an increased fraction of carbon black. The use of this material reduces the speed of the abrasive abrasion of the tread. The depth remains stable even after several tens of thousands of mileage kilometers.
Comfort
In matters of comfort, some complaints are presented to this model. Manufacturer Nitto Therma Spike equipped the presented tires with spikes. Therefore, riding noisy. To reduce the resonance does not even help the variable location of the tread pile.
Soft moves high. This is implemented through the use of polymer materials in the framework. Shaking in the cabin is missing as such.
Trying to consolidate in the US market, the Japanese company Toyo Tire in 1995 created the Nitto brand. The enterprise products were intended solely for powerful premium sedans, sports cars and SUVs. Gradually sales started in Europe and Russia.
The company's line has different types of tires. Among the drivers, the winter model Nitto Therma Spike uses in great demand. Reviews of the presented rubber in most cases are only positive.
Production and design
The model was created with the active application of various technological innovations. For example, the design of the tread was designed using digital simulation methods. After creating the prototype, engineers started testing at the Toyo polygon. Only after bringing the model to perfection under these conditions, the tires were allowed into the series. Multi-level quality control, certified ISO, eliminates the risks of acquiring a retail of defective tires Nitto Therma Spike. Motorists testify that the quality of tires is consistently high.
Tread design
It is worth mentioning that the concern moved from the adopted canons in the design of winter tires. Tires received a revolutionary asymmetrical tread pattern. The outer part is quite large, consists of large quadrangular blocks. Massive elements retain their resistance with sharp deformation loads. As a result, the vehicle maintains stability during the passage of turns and in braking.
During the tests of Nitto Therma Spike, it turned out that the presented sample of the tire allows you to maintain a motorist phenomenally high speed of maneuvers. Wheels quickly respond to any changes in the steering.
The inner part gives stability with rectilinear motion. The vehicle is well holding the road, demolitions during the speed set are missing in principle.
Two compound
The outer and inner parts of the winter tires Nitto Therma Spike are different not only by design, but also by the type of rubber mixture. In the first case, a tougher composition is used. It is it that allows you to preserve the necessary maneuverability and the quality of movement. In the second, manufacturers in the compound increased the share of elastomers. As a result, the tire behave more gently, do not provoke high shaking in the cabin when moving through a bad road surface.
The use of special compounds allows you to expand and temperature operation. Tires retain their elasticity even in a heavy frost. Reviews of Nitto Therma Spike drivers argue that the rubber of this class is able to withstand extremely low temperatures.
Behavior on ice
During test test tests, Nitto Therma Spike showed almost perfect ice behavior. The clutch quality is high due to important technical solutions.
- First, spikes are located in 14 rows. This allows preventing the formation of a rut effect. The car retains his maneuverability even on the glaced tracks.
- Secondly, the spike head has a variable cross section. Such an unusual approach allows to maintain the stability of turning and braking. Demolitions are absent in principle.
- Thirdly, special small notches are applied to the tread blocks. As a result, the rigidity of all elements increases, the total number of clutch edges increases.
Snow and water removal
Reviews of Nitto Therma Spike drivers mark and stability ride on a wet road. The negative effect of hydroplating, formed due to the occurrence of the micropoline of water between the tire and the road, is completely absent. This is implemented thanks to a number of measures. For example, Nitto Therma Spike tires received a developed drainage system. The liquid quickly enters the longitudinal channels, then it is redistributed over the entire tire and removal from the contact spot. Improve the clutch quality allows the increased proportion of silicon dioxide used in the compilation of the compound.
The dimensions of the drainage tubules allow the tires to quickly remove the snow hinged on the protector. It just cleans with the depths of the tread under his own severity.
Durability
In reviews of Nitto Therma Spike drivers celebrate and high enough mileage. Tires can withstand about 75 thousand km run. Naturally, the ultimate figure largely depends on the style of the motorist control. After installing the wheels, it is necessary about 1 thousand km to overcome in the most gentle mode. The driver must avoid high speeds and sharp braking. This will allow the spike to be more tightly fixed in the installation places and prevent their premature loss.
Improve reliability helps the use of reinforced frame of a frame. Metal threads are binding to an elastic polymer. As a result, it is possible to more fully redistribute external deformation loads. The risk of forming cones and hernia is reduced to zero.
In the production of rubber mixture for tires NITTO THERMA SPIKE, technical carbon is actively used. The compound reduced the speed of mechanical abrasion.
The optimized distribution of external pressure leads to uniform wear of the tire. The emphasis on the central part or external is missing.
Often, when choosing rubber, the buyer is focused on producers whose names are for hearing. But do not forget that there are no less famous brands that for one or another no reasons were not previously represented. This can be attributed to the Japanese company Nitto, based (already!) In the distance 1949. On the test we have a winter studded tires THERMA SPIKE
Getting a set of tires for testing, and even studded, I did not expect the weather this winter decide to play with us in hide and seek. Of course there were frosty nights, and narrow streets with a mirror-pure icy coating. But still to fully enjoy the winter with a frozen asphalt, a snowy interhesion, flying in all directions, has not yet succeeded. Well, nothing, in the winter at least there is another legal month in stock. Receive. Therefore, all the tests had to be carried out in the mountains - every weekend of the gas tank arrow in the letter F for safety, the camera is charged, the thermos is filled. Fresh air and beautiful views. And without good rubber, not very much and it will all enjoy everyone. Because of frequent shifts, the road turned into an ice slide with a very oblique bias. With this, I had to face our test participant.
Therma Spike is performed in almost all popular sizes for passenger cars. In the photo of the tire 205/55/16 
Nitto specialists used the most useful tread area - everything is written by wide and narrow grooves, lamellas and saw-shaped edges of the blocks. The depths of the projector are enough to not go into deep snow At first glance, the tire causes mixed feelings. A rather original asymmetric pattern with a huge amount of lamellae and wide grooves causes a sense of confidence that rubber will not let go in most situations with which you will come across the road. On the other hand, a non-standard misinterpresentation - as seen by the photo, the total sweepability of the tread spikes is low. And the particle of doubt may be painted on the patience on icing coverage. But this is at first glance. In practice, rubber behaves very worthy. This has its Japanese calculation. This layout, in my opinion, allows you to solve several tasks at once: on a solid asphalt coating and on a snow-covered road, scattered spikes do not interfere with the main pattern of the tread, leaving a large area of \u200b\u200bthe contact spot. The smoothness of the stroke improves and the noise level decreases.
Although Hyundai i30 and has a sufficiently low lumen (150 mm), surprisingly to everyone passing by SUVs, all difficulties were overcome. And not without the merit of tires. The car was confidently harvested from a deep rut and without much effort allowed to touch with a strong slide on slippery road 
Serpentine on a dam leading on Bao is covered with a crust of snow and ice in a silent silence of the fog descended. Nature sleeps. If you do not take into account the designs built by a person, the landscape is very much reminded of scenes from the series "Game of Thrones" As indicated on the official website, Nitto specialists have developed the Therma Spike bus solely for harsh winters. To do this, they used a lot of branded technologies. For example, the closed lamellas on the inner part of the tread (3D Interlocking Wave) must provide confident adhesion during acceleration and braking both on ice and on a dry surface, while providing more uniform wear. And the multi-wave lamellas on the outside (3D Multi-Wave) are responsible for confident driving when maneuvering and coursework resistance when driving in a row. As for the spikes, they have a X-shaped and double edge. This form allows the spike to work in different directions, improving the grip and the dynamics of overclocking.
In general, without going into the details of all these technologies, I will say - the fact remains a fact. Rubber confidently feels like on asphalt and in the snow and ice. Records on Sllyoma on it you do not put, but you can always get out with friends or family in the snow-covered mountains to enjoy nature and breathe fresh frosty air.
