But first, it makes sense to recall those solutions that were originally incorporated into the design of the Snow Cross winter tire. The very name of one of the technologies (Snow Cor) used in this model indicates that the developers paid special attention to the tire's performance on a snowy road. The directional tread design features a closed center rib. The essence of the solution lies in the fact that the rib cuts through the snow cover, effectively removing the upper, usually wet layer of snow from the contact patch through angled grooves. And this greatly reduces the possibility of "aquaplaning in the snow". Good drainage in the contact patch is also facilitated by the Z-shaped sipes, which penetrate the tread blocks. Opening and closing during the movement of the tire, the sipes not only remove the water suspension from the contact patch, but also create additional zones of engagement of the tire on the snow cover. But why did the developers of Cordiant choose this shape of the lamellas? For example, the frequently used 3D sipes can cope with the above functions and provide the rigidity of the tread blocks, which has a good effect on handling. It is worth remembering here that any tire is a child of compromise. And it is important for developers to achieve a balance of all characteristics. Cordiant engineers experimented a lot with lamellas (and not only in 3D form) and, as a result, came to the conclusion that the lamellas of their chosen shape, firstly, perform well the functions assigned to them, and secondly, they are less expensive in production.
Innovative cleat shape ensures secure grip in the tire
Cordiant Snow is studded with Ice Cor's proprietary technology. These are asymmetrically located studs, the number of rows of which is 16. Thus, in the contact patch of the tire with the road at least 10 studs are simultaneously located.
What new solutions have been used in this season's Snow Cross winter tires? First of all, this is a new spike developed by the renowned company Scason. The body of the spike is aluminum and the insert is made of tungsten carbide. As with sipes, many tests have been carried out with the spikes. Five options were pre-selected, from which the final choice was made. The shape of the carbide insert is two squares shifted relative to each other, that is, the insert has eight sharp edges, allowing you to confidently grip the ice. The shape of the spike leg was selected in such a way as to ensure its reliable fastening in the tread layer of the tire under shock loads. In comparative tests of tires equipped with old and new studs, only due to the use of the novelty, the brake was reduced by 8%, and the lap time on the ice improved by 7%. Acceleration on ice has also improved.
16 rows of studs (factory studded only) asymmetrical
A separate "engineering" topic is the new rubber compound, which took three years to develop, and the work was carried out in partnership with colleagues from German institutes. But the time was well spent: only due to the new compound, the braking distance was reduced by 12% (at a speed of 20 km / h this is the body of a passenger car), and acceleration on ice improved by 9%. The new rubber compound not only became more elastic, but also expanded the temperature range of its use. An argument that is very important in determining the market for which the tire is intended: the rubber compound of the Snow Cross model of winter tires remains stable up to a temperature of -53 ° C. Structurally, the tire has a two-layer tread: directly under the tread with a soft rubber compound there is a hard, so-called base layer , which, first of all, provides a reliable fastening of the spike. In addition, this layer creates a reliable support for the cleat, thereby exerting additional pressure on the cleat during contact with the ice surface.
For the winter season 2016–2017, the Cordiant Snow Cross range of tires has been expanded by 25 standard sizes. There are new popular sizes with 17 and 18 inch rims. Moreover, a whole line for the production of these tires was launched at the Cordiant-Vostok plant. There are also 13 standard sizes of tires for SUV cars: the design of tires for cars of this segment has a reinforced sidewall.
In such weather as in the poem "The Twelve" by Alexander Blok, only studded tires will help. To make it easier for the buyer to choose, the ZR expert group tested 12 sets of relatively inexpensive 15-inch "studs".
There is a crisis in the yard, prices are rising, incomes are not in a hurry for them - and people are increasingly looking at more affordable cars. And the majority of inexpensive foreign cars and domestic cars are shod in tires of 195/65 R15 dimension.
Eight tires from the Za Rulem magazine tested by an expert group fit into the price bracket from two to three thousand rubles apiece. The lower threshold was set by IceLink of the Chinese company Triangle, which is gradually gaining popularity in Russia, and the updated Cordiant Snow Cross. The top bar in the budget company is supported by the upgraded Hankook Winter i * Pike RS + tires with an increased number of studs to one hundred and seventy and the new Dunlop model SP Winter Ice 02. The new Matador Sibir Ice 2 model and the already popular Pirelli Formula tires fit into the middle. Ice, Toyo Observe G3 ‑ Ice and Nordman 5.
The experts also took four models, very successful in Russia, from among the most powerful, but expensive - these are Goodyear UltraGrip Ice Arctic, Michelin X-Ice North 3, Continental ContiIceContact 2 and Nokian Hakkapeliitta 8. By the way, half of the tested tires were made in Russia, and localization allows you to keep reasonable prices.

It's time to go North
Last fall, the experts of the magazine "Za Rulem" sadly recalled the rainy January and February 2015, when the test group rushed around the AVTOVAZ test site in search of a snowy area that had not yet been completely washed away by the rain. It was then that it was decided the next time to try to escape from the warm winter, which has become a frequent guest in central Russia, to the north of Finland. Nokian has kindly provided the White Hell test site on Lake Tammijärvi for the "white" tests.
At the end of February, pre-run tires were delivered to Lapland, and in the first half of March, the main part of the winter tests was carried out on a Skoda Octavia car - on snow and ice. Even in the first month of spring, real winter reigned beyond the Arctic Circle - unlike the Volga region, where it turned out to be unusually warm and practically snowless. In general, the experts did the right thing by going north. And not only because of the weather. Still, the conditions of a specialized tire range not only simplify the work, but also allow additional tests and more information to be obtained for evaluating each model.
All snow and ice exercises of the magazine "Za Rulem" were performed in "White Hell" at an air temperature of –20 to –2 ºС. Unfortunately, the experts had to abandon the rearrangement, since there was no dense, packed snow. And on a soft track, a deep track quickly forms, the sides of which serve as a kind of lateral emphasis and do not allow correctly assessing the lateral grip of tires on snow. But the controllability assessment was carried out on two special tracks - snow and ice.
Snow and ice procedures
The experts start with methodical measurements, repeating the runs for each set of tires six to eight times, and if the results jump, then ten times. After every two to three sets, they check the condition of the coating using the base tires and, taking into account the data obtained, recalculate the results.
On a large horizontal plateau, an expert team is engaged in acceleration and braking in the snow. Traction control and anti-lock braking systems are zealous to ensure that the wheels do not slip during acceleration and do not lock up during braking. The acceleration time is fixed from 0 to 40 km / h. From scratch - because some tires "hang" when starting from a standstill, and 40 km / h - because this speed can be picked up in the first gear, eliminating the measurement error due to switching to the second.
Braking from 40 km / h, but already up to 5 km / h, and not to a complete stop. The fact is that at very low speeds, the ABS sometimes allows the wheels to lock, lengthening the braking distance and introducing inconsistencies in the measurement results. After evaluating several sets, the surface of the plateau is "flattened" by the snowcat, which the Finns call it tampa-a-ari.
The first leaders are gradually determined - Cordiant, Formula and Nokian. Toyo has the last result. In terms of braking, Michelin was the best, and the Chinese Triangle was the outsider.

For measurements on the ice, the expert group moves to a special track covered with a huge long awning that hides the ice from snow and bright sun - the results are more stable than in open space. In Togliatti, even if the weather is favorable, it would take much longer. The procedures are the same as on the snow, only the final acceleration speed and initial deceleration are only 30 km / h. And the acceleration time is measured not from the moment of starting, but from a speed of 5 km / h. The fact is that the tent with the snow lying on it "closes" the sky, preventing the VBOX equipment from communicating with the GPS satellites. Therefore, when accelerating and decelerating on ice, a Dutron measuring device with an optical sensor was used, which makes mistakes at walking speeds.
With each measurement, the tester moves the car slightly to the side, onto clean ice. When the ice rink is completely covered with fine ice crushed by spikes, Multicar is selected to the arena and sweeps the ice. Particles of ice and snow trapped under the tires act like balls in bearings: they reduce friction, increasing acceleration time and braking distance.
The best accelerating dynamics on ice was provided by Nokian tires. Continental finished second, followed by Matador. On braking, the same alignment of leaders and outsiders remained.
The experts complete the measurements by determining the time for passing the ice circle, winding 10-12 "turns" on each set of tires. Conti and Dunlop take the lead.
Expert work
Vehicle behavior is assessed when driving on a snowy road at high speed. For this, a platform with a width of about fifteen meters and a length of at least five hundred is used. Such an elongated field with soft snowdrifts around the perimeter allows you to fearlessly check the clarity of straight-line movement at speeds up to 90-100 km / h, as well as simulate obstacle avoidance and soft lane changeover from one lane to another.
On Cordiant, Goodyear and Nokian tires, the Skoda test feels more confident than others. Least of all the experts liked the Matador: wide and uninformative "zero", delays in steering responses and significant steering angles when adjusting the course. The Chinese Triangle tires surprised us with their clarity. True, the rating was slightly lowered due to the low information content of the steering wheel in the zero zone.
Not far from this long plateau, the Finns have paved a closed-configuration snow track with turns of different curvatures, small ups and downs - an excellent imitation of Russian roads.
Here Skoda is more stable to drive on Cordiant, Hankook, Nokian and Toyo tires - the experts won over the clear reactions and understandable behavior of the car even in sliding. Triangle turned out to be the laggards: for Skoda, shod with these tires, the steering wheel becomes uninformative, it has to be turned at large angles, the car goes too sweeping, with long slides - from drifting at the entrance to the turn to skidding on the arc.
On the ice of Lake Tammijärvi, a track was prepared to assess handling on very slippery surfaces. A good lane combining fast and slow turns with short and long straight lines.
In the middle of the closed track, there is snow with a depth slightly more than the ground clearance. Just what you need to check the patency. Here the experts focused on how easy and understandable the car is to start, move and maneuver in deep snow. And how confidently it gets out back in its own footsteps, if it suddenly gets stuck.
When "taxiing" on ice, Cordiant, Hankook, Nokian (this trio were the most successful in handling on snow) and Nordman bypassed everyone thanks to clear reactions and understandable, predictable behavior. Goodyear's spikes deserved the lowest rating due to the low information content of the steering, an unexpectedly sharp break into a skid and a long recovery of grip after the start of sliding.
On the other hand, Goodyear tires were second to none in flotation! Skoda on them made their way through the snowdrifts like a bulldozer, raking the snow with the front bumper. And worse than others, the Triangle tires get along with snowdrifts - the car crawls through deep snow with difficulty, very hesitantly and reluctantly. On these tires it is hardly possible to get out of a visible parking lot onto a cleared road.
Adventure with thorns
After the snow and ice tests, the spikes were recounted. ContiIceContact 2 and Formula Ice became champions in the reliability of fixing "studs" - during the tests they did not lose a single stud! The Michelin X-Ice North 3, Nokian Hakkapeliitta 8 and Nordman 5 tires showed good results: from all four wheels each left only two studs. Goodyear UltraGrip Ice Arctic, Matador Sibir Ice 2 and Triangle IceLink each missed three or four studs. The Toyo Observe G3 ‑ Ice tires were even weaker: the loss was seven studs per set. The three lagging behind are the upgraded Cordiant Snow Cross (ten pimples from the set lost), Dunlop SP Winter Ice 02 (thirteen) and Hankook Winter i * Pike RS + (fifteen).
Now comes the fun part. The largest number of studs on almost all tires has lost the left front wheel. The front is logical. The front ones skid when starting and accelerating, they bear the main load when braking. But why left? Experts have not seen anything like this before ... The fact is that the ice circle at this test site is much larger than ours in Sosnovka, and therefore the speed is about twice as high. And since the car goes faster, then the inner wheel - and the left one, since we were driving counterclockwise - is more unloaded and slips more.
The spikes are more likely to fly out precisely when slipping, and when unloading the wheel. On a loaded wheel, the rubber is squeezed more by vertical force, it covers the spikes more and holds them better. This means that in everyday use, the spikes often fly out during acceleration, and not during braking. If you want to save them, limit wheel slip while accelerating.
On the asphalt
Exercises on the "black" roads were held at the junction of April and May, when the asphalt was already dry, the wind died down, the air temperature was from 4 to 7 ºС. This is the temperature limit for the seasonal tire change. How will the "spikes" behave in these conditions?
The first exercise is measuring fuel consumption. On the warm-up lap just before the measurements, directional stability on the asphalt and comfort - noise and smoothness - were assessed. At the end of the measurements, a “run” was made on roads with different surfaces in order to fully assess the level of comfort.
The most economical tires at city and suburban speeds were Formula, Nokian and Nordman tires. The highest flow rate was given by Cordiant. Although the difference, in all honesty, is scanty: 200 ml of gasoline per 100 km.
At a speed of 110-130 km / h, the Skoda Octavia keeps its course most clearly and makes soft changes, being shod in Michelin tires. And most of all, the driver is annoyed by the Triangle: smeared, very wide "zero" and lack of information content. To correct the direction of movement, the steering wheel has to be turned at large angles.
In terms of noise level, there is no significant difference between the tires crunching on the asphalt with spikes. In terms of ride quality, the Continental, Hankook and Michelin tires stand out for the better.
Tests are completed by evaluating the braking properties on wet and dry asphalt. Experts are interested in the braking distance from speeds of 60 and 80 km / h to a speed of 5 km / h (to cut off the possible influence of ABS). Continental tires perform best on wet pavement, with Dunlop and Cordiant taking the longest distance. On dry surfaces, Triangle tires have the shortest stopping distances, while Cordiant tires are the outsiders.

Summary
With a score of 929 points, the Russian-made Nokian Hakkapeliitta 8 tires won. Second place went to ContiIceContact 2 tires (916 points). The disadvantage of both is, by and large, one - the high price. Goodyear UltraGrip Ice Arctic is in third place, having lost six points to the coveted mark “900” (the tires that have earned 900 points are considered excellent by the experts of the magazine “Za Rulem”).
For those who are not ready to pay more than 12 thousand rubles for a set of four tires, testers are advised to take a closer look at the Hankook Winter i * Pike RS + and Nordman 5 models - these are very good tires, they did not fail in any of the parameters.
The next five contestants, who scored from 850 to 870 points and took places from six to ten in our table of ranks, are also good, but each has its own disadvantages. Of these, experts consider the Cordiant Snow Cross tires the most profitable purchase: a modest price is combined with fairly high performance. However, these tires are not very suitable for urban conditions with clean asphalt roads.
The price of Michelin X-Ice North 3 tires can be considered slightly overpriced, not quite corresponding to the level of performance. Matador Sibir Ice 2 and Triangle IceLink are frankly budget products by their characteristics, but with careful driving you can survive the winter on them ..

Test material prepared using the article of the publication
Initially, the task was to prepare for the production of tires with a rim diameter of 17 and 18 inches for cars of the premium segment. However, such products require not just good products, but very good ones. The tread pattern of the Cordiant Snow Cross was kept the same, but the mixture was re-developed. Its chemical composition made it possible to provide a wide operating temperature range: + 10 ... -53 ° C. Before modernization, the lower limit was -45 ° C.
To improve grip on ice, lightweight Spike-Cor studs from Scason were used. The aluminum body of the new "claw" has an octagonal carbide tungsten carbide insert. Previous spikes were wrapped in a stainless steel body, their carbide insert had no faceting.
A dozen of these "claws" are constantly in the contact patch. According to Kordiant, the braking distance when decelerating from 30 to 5 km / h on modernized tires decreased by 8% compared to the previous ones, and acceleration from 5 to 30 km / h became faster by 3.7%.
The modernization affected not only the expensive 17- and 18-inch models, but also the more affordable 13-16-inch models.
On the snow-covered field of the Sortavala airfield, shinniki assembled rear-wheel drive cars of premium brands. The test program of the upgraded Cordiant Snow Cross model included an assessment of longitudinal adhesion: after intensive acceleration to 60 km / h, sharp braking until a full stop, first with ESP on and then off. Clearly working electronics drive the car without skidding and slipping. But even without electronic stabilization, I confidently controlled the behavior of the BMW five on the snow.
I tried to evaluate lateral grip while driving a Mercedes E-class, performing a "moose" test. I didn’t knock a single cone while performing maneuvers, but I don’t undertake to say something about the advantages of the new tires without comparing with the previous ones.
In a tire test carried out by the Za Rulem expert group (ZR, 2016, No. 9), the updated Cordiant Snow Cross spikes performed well. In 15-inch dimensions, they outstripped the famous rivals Michelin and Dunlop. And the price is one third lower: depending on the standard size, Cordiant Snow Cross tires cost from 2,000 to 4,000 rubles.
19.10.2015 Studded tires:
- Continental IceContact 2
- Cordiant Snow Cross
- Dunlop ice touch
- Gislaved Nord * Frost 100
- Hankook Winter i * Pike RS Plus
- Maxxis Arctictrekker NP3
- Pirelli ice zero
- Toyo observe g3-ice
Friction tires:
- Continental ContiVikingContact 6
- Cordiant Winter Drive
- Goodyear ultragrip ice 2
- Maxxis SP-02 Arctictrekker
- Nokian nordman rs
- Toyo Observe GSi-5
Among the novelties in the test were the Continental IceContact 2 winter tires with an increased number of studs (190 studs), the Hankook i * Pike RS (170) and the new version of the Goodear UltraGrip Ice Arctic tires with a reduced number of studs (100 studs). The Nokian Hakkapeliitta 8, Nokian Nordman 5, Pirelli Ice Zero, Cordiant Snow Cross, Dunlop Ice Touch and Maxxis Arctictrekker NP3 also have a large number of studs. We remind you that in European countries from July 1, 2013 there is a limit on the number of studs - 50 per 1 running meter of the tire tread. From January 1, 2016, a similar restriction will appear in Russia, but with a limit of 60 spikes per 1 running meter. It is not difficult to calculate that for tires of size 205/55 R16 the limit will be about 100 studs. What, then, to do with tires with more studs? Don't panic, everything is legal! To do this, companies that want to install too many studs on their tires need to prove that this will not increase road wear. To achieve this, manufacturers install lightweight studs, use a special studding system, etc.
Tests
Driving a car on a winter road requires a greater concentration of attention, experience and knowledge from the driver, since it includes all types of weather conditions: sun, rain, snow and ice. Thanks to modern technologies, it was possible to create the necessary weather conditions for the test at the winter training ground. A special heating system melted the ice in front of the pits and the entrance to the frozen lake, and a special "vacuum cleaner" shook, swept and blew snow off the track. The weather also helped - on the eve of the passability test, it started snowing.
To measure the characteristics when driving on a wet road, it was decided to return to Sweden in April, but to another training ground - to the city of Gislaved. There, not far from the buildings of the former tire plant of the same name, there is a polygon with several tracks, one of which is equipped with the irrigation system necessary for this test.
results
The winners of the ice track test were Nokian spike and friction tires and the new Continental IceContact 2 for the season. Overall, this test was won by studded tires. On the ice circle, the situation is somewhat different - this is due to other characteristics of the ice surface. The top picks were Continental IceContact 2, Nokian Hakkapeliitta 8, and Goodyear UltraGrip Ice Arctic.
On the snowy track, Goodyear UltraGrip Ice Arctic, Cordiant Snow Cross and Pirelli Ice Zero became the leaders. They have shorter braking distances and shorter acceleration distances on loose and packed snow. The best in the winding track test are the Nokian Hakkapeliitta R2 and Cordiant Snow Cross.
On the wet road the studded tires Gislaved Nord * Frost 100, Nokian Nordman 5 and Pirelli Ice Zero proved to be the most efficient, and on dry - the frictional Continental ContiVikingContact 6 and Goodyear UltraGrip Ice 2. The quietest tires among the participants were Goodyear UltraGrip Ice 2, Continental ContiVikingContact 6 and Cordiant Winter Drive.
The results of each test were tabulated. Studded tires were marked in yellow and friction tires in green.

In the past 3 years, the tires of the Cordiant concern really please, the quality is growing, and with it the army of satisfied fans of inexpensive high-quality tires is growing. In today's review, we will consider the novelty of 2013, which has been in trend for 2 years already, and has been collecting a huge number of positive reviews. Meet the Cordiant Snow Cross studded tire.
All as one users, seeing the tread pattern, start screaming - this is a clone of Hakki 7, do not think that you buy Cordiant and get the same Hakku, the difference is huge and blah blah.
Of course, comparing a Finnish tire and ours with a 3-fold price difference is a wrong job. Whoever has money - he takes Hakku without hesitation and does not care. Those who have no money - they have to look for reviews on the internet, shovel mountains of information, look for tests, videos and other information. Even when testing tires, they are taken from the same "weight" category - premium, comfort, budget. And comparing the tires of the budget class with the comfort class is simply pointless. In most tests, the expensive tire will be ahead, but how much? And is it so important in daily use? In general, let's talk better about Snow Cross - according to the test results and numerous reviews, it is really worth paying attention to. A photo:
The previous Snow Max model also showed great results, people are happy as an elephant. And Snow Cross is a continuation of Max's technologies, Cross is even better, more adaptable, more technological if you like. Tire technology is not standing still and the best tires of 2005 will now show very poor results. That is why the people are studying the novelties of the market, because they will surely be better than the previous ones. Progress cannot be stopped.
Cordiant Snow Cross - studded rubber, the composition of the rubber compound is still improved, there is even more silica, and therefore the tire remains soft even in severe frosts (-30), so that the tire after a long night frosty parking will not be square, but will remain round)) Well and a winter tire must always be soft - this is a priori!
The tread pattern is similar to the Hakku-7, but superficially and structurally, there are considerable differences. Nevertheless, according to the opinions of the people (a lot of them have accumulated over 2 years), the tire digs deep snow excellently, loose snow is also excellent. Snow porridge - great, water and moisture-saturated snow are well removed from the contact patch. Photo of Snow Cross:
But the photo of Hakki 7 for comparison, there is a difference and it is noticeable, so there is no need to la-la, that the tread is the same (in Hakki, the spikes go almost non-stop throughout the tire, in Kordiant - much less often):
Cross studs are again a new technology, the shape of the tire and its insides, fit. As a result, the loss of thorns is minimal, it is, but in comparison with its competitors, Cordiant is really better. Which of the competitors lost? Such a popular Nokian Nordman 4, which is good for everyone, but does not hold the spikes as cool as we would like. Of course, no one has yet canceled the correctness of the run-in, but nevertheless, according to the reviews of the people, it is clear that Snow Cross's spikes really hold better. And if you compare with Yokohama IG35 - here you yourself know, Yokka holds on ice perfectly only the first season, in the second - she already has no thorns))
By the way, we will recommend another chic option, but already a Velcro tire - the quality is the highest, the reviews are overwhelmingly excellent. Well, the price is great. If the city is cleaned and the temperature allows, be sure to take it.
On ice, the Snow Cross shows excellent results for a budget tire (and the difference between tires of a different price category is minimal). It is not always possible to start a car into a skid on purpose, and if you drive on a winter road with your head, then the hold on the ice will be 5 points.
Video - test on loose snow
In the snow - this tire is just made for him. Rolled snow - 6 out of 5 points, loose, wet, deep - ideal. It digs snow smartly, side hooks for "digging" and for removing water are wide and deep.
What are the downsides? We read in the reviews - they slow down badly on bare asphalt at +5. Hehe, these are spikes and a priori they should slow down badly. Hakka 7 will also slow down badly, but probably a little better than Snow Cross))
Another disadvantage is poor balancing. This is not a fact, it all depends on the tire you come across. In most, it is completely balanced, but there are exceptions. This means that the workmanship is not keeping up and this is bad. On the other hand, buy tires immediately with tire fitting, and if there are too many weights, ask for another tire, they will replace it without problems.
In general, we boldly put 4.5 points to rubber, in the budget class it is really one of the best. Not long ago, as yesterday, we saw Shevik on this rubber, came up, talked - the owner is terribly pleased, he drives a lot in the snow and likes to park in snowdrifts when there is no parking space. With this rubber he has no problems at all. All types of winter road surfaces are ideal, except for bare asphalt - here it is a little worse. We definitely recommend buying, an excellent inexpensive spike.
