Plus detailed video. How many studs are on winter tires

The eighth generation Hakkapeliitta spikes were tested on the updated (2015 release) Mitsubishi Outlander with a 2.4 liter engine. Recall that shoes of size 225/55 R18 SUV are recommended for this model, where the last three characters indicate that it belongs to the crossover segment. This is an important nuance that should be taken into account when choosing seasonal tires - Nokian's product range may contain tires of the same size both with and without the SUV index. The latter are intended for ordinary passenger cars. Therefore, in order to make it easier for yourself to find the right models for your car, we recommend using the online tire selection service, which operates on the manufacturer's website.

For more than four months of operation of the Hakkapeliitta 8 SUV, we have rolled over 10,000 km on the capital's roads and country roads of the Moscow region and the Vladimir region. Winter this year was, let's say, not quite winter. There were practically no severe colds, and infrequent heavy snowfalls were abruptly replaced by warming with freezing rains, which often turned the road surface into an impassable mess of wet snow, alternating with icy asphalt. On the other hand, slushy weather presented us with a good opportunity to practice in the most difficult road conditions. And in this sense, according to the general opinion of our test editors, the Nokian Hakkapeliitta 8 SUV showed itself from the best side. As we have seen for ourselves, these tires perform well on any type of winter surfaces, whether it is hard or loose snow, ice, slush or wet asphalt covered with snow porridge.

(acceleration, braking, driving at a constant speed) "eight" provides guaranteed grip and good handling. We can confidently say that the Hakkapeliitta 8 SUV demonstrates an excellent balance of grip properties in the longitudinal and transverse directions, while ensuring relatively low noise when driving on asphalt.

All these qualities of the tire have become possible due to the introduction of innovative technologies in its production. So, the tire tread uses a unique second-generation Hakkapeliitta Cryo-Silane winter compound, created specifically for difficult winter conditions. Thanks to it, the sipes of the tread blocks maintain a good level of grip during sudden changes in temperature. The main components of the mixture are silica, rapeseed oil and more natural rubber. The latter has a key effect on the grip properties in extreme conditions on a winter road. Natural rubber is a kind of stabilizer in a wide range of temperatures up to severe frosts.

Another tire feature is the original symmetrical directional tread pattern. It is formed by a developed network of deep diverging (towards the edges of the tire) grooves and a central part where the tread blocks are firmly connected to each other to increase the rigidity and stability of the tire's running characteristics. At the same time, this design of the treadmill provides it with good self-cleaning from snow and dirt, as well as low rolling resistance.

Separately, it is worth mentioning the spikes used in. None of them flew out of the protectors during the tests. Apparently, the new Nokian Eco Stud 8 studding concept, implemented in these models, played its role. This concept involves the use of a multi-faceted anchor stud of a new generation, equipped with a specially shaped flange, and a softening “cushion” under the stud (Eco Stud) made of special soft rubber. The new flange significantly reduces stud deflection, and the pad improves stud traction and softens contact with the road. This innovation has already been used in other winter tires Nokian Hakkapeliitta, but in the "eight" the thickness of the "cushion" is increased.

Winter studded tire. The main features declared by the manufacturer:

• unparalleled reliable grip in winter conditions,
• low fuel consumption,
• acoustic comfort,
• reducing the level of damage to the roadway,
• directional stability and steering sensitivity.

Hooks like never before.

These tires with more studs have taught us superior performance on ice. And in deep snow with slipping, these tires row better than others.

But there are also side effects: average grip on the pavement and, most importantly, the constant high-frequency noise of spikes clattering along the road. Unpleasant resonance - about 70 km / h.

After the test, three spikes per set were missing.

Nokian is not the best option for large cities, but on regional icy roads Hakkapeliitta 8 is what you need.

The advantage of Nokian Hakkapeliitta 8 tires on ice is obvious: biting into the ice with their 190 spikes, they provide the shortest braking distance and the best acceleration dynamics. The directional tread works well in packed snow, although the tires don't paddle well when driving with slip in loose snow.

Excellent winter tires.

On dry pavement, a soft tread (the lowest rubber hardness among studded tires) does not hold heavy loads, significantly increasing the braking distance. Spoils the impression of driving on asphalt and a loud itching of spikes.

Like it on any winter roads and off-road, will help save fuel.

Three novelties were waiting for me outside the Nokian test site in polar Ivalo: Hakkapeliitta 8 studded tires and two models of so-called friction (that is, without studs) winter tires - Hakkapeliitta R2 and Hakkapeliitta R2 SUV. And if friction tires are rather a product of “moderate progress within the framework of legality”, then serious passions flared up around studded tires - not so much in connection with progress, but with legality: there were more spikes than in the tread of the Hakkapeliitta 7 predecessor tires. And this is contrary to the new European rule, which severely limits the number of spikes per linear meter! Or does it not contradict?

On the one hand, it is obvious that the more spikes in the tire, the more reliable the movement on ice. Of course, taking into account the fact that such tires are driven not only on snow and ice, the "density" of the spikes should have reasonable limits. In addition, spikes cause enormous damage to asphalt concrete pavements. That is why in most European countries spikes are completely prohibited, and in those countries of Northern Europe where spikes are allowed, their number, weight and size are strictly regulated. So, on 14- or 15-inch tires, a maximum of 110 studs are allowed, on 16-inch tires - 130. And from July 1, 2013, an even stricter rule is introduced: there should be no more than 50 studs per linear meter of tread! This means that the "density" of the spikes should be reduced by about a quarter. If, for example, there were 130 studs on the popular model Gislaved Nord Frost 5 in 205/55 R16, now there should be 96.

From July 1, 2013, tires with more than 50 studs per linear meter of tread can only be sold in the Nordic countries if they successfully pass a special test proving that these tires are harmless to the road surface. The procedure is as follows: pre-washed, dried and weighed granite tiles are placed in a square cut in asphalt. After 400 passes (200 cycles on each side) of the car on the “calibrated” place at a speed of 100 km/h, the tiles are again sent to the scales - the mass loss should not exceed the losses after the same tests of reference tires with 50 spikes per linear meter

Tire manufacturers know about such innovations in advance, so they usually have enough time to develop models taking into account new requirements. For example, this year's novelty, the Michelin X-Ice North 3 studded tires: the number of studs has already been reduced by a quarter! And suddenly I find out that the new Nokian Hakkapeliitta 8 tires of the same dimension 205/55 R16 no longer have 130 studs, but ... Already one and a half times more, 190 pieces!

Studded tires are the backbone of Nokian Tires' fortunes: they account for 75% of global winter tire sales. Now the bet is not just on studded, but on heavily studded tires - in the tread of Hakkapeliitta 8 tires as many as 190 studs against 130 for Hakkapeliitta 7 tires of the same dimension

It turns out that the new European regulation still left a loophole, which, to the poorly concealed annoyance of other manufacturers, Nokian Tires took advantage of. If the manufacturer proves that exceeding the standard number of studs will not lead to an increase in the destructive effect on the road compared to the reference tire, the number of studs in which complies with the new regulation, then - you are welcome! Naturally, the procedure for such tests is also provided. But there are juicy details. This procedure was also developed by the Finns - specialists from the independent testing center Test World, and the tests of Hakkapeliitta 8 tires were carried out by Nokian Tires specialists at the "home" test site in Nokia under the supervision of an official representative of the Finnish traffic safety agency TraFi. According to the results of these tests, Nokian Hakkapeliitta 8 tires were recognized as fit for use in the Scandinavian countries. And, of course, in Russia and Ukraine, where there are no rules at all regulating the number of spikes.

Reducing the harmful impact on the road surface is achieved thanks to the Eco Stud 8 concept! - Proudly comments Matti Morri, Leading Technical Expert at Nokian Tires.

The spike itself retains the hex section already familiar from Hakkapeliitta7 tires, but is 0.5mm shorter and 20% lighter - it now weighs 0.8 grams. In addition, a small cavity appeared in the support flange: when the stud comes into contact with the road, the base of the flange presses on the rubber pad, forcing it not only to compress, but also to go deeper into the cavity, that is, the air in the cavity works like a pneumatic spring.

The Eco Stud 8 concept: a lightweight spike and an enlarged rubber cushion under it, which, compressing and partially filling the cavity in the support flange, softens the impact of the block on the road

Along the way, as Matti assures, it was also possible to reduce the noise level: they say, the spring pad turned out to be an effective “silencer”, which made it possible to abandon the drop-shaped holes in front of the spikes, which helped reduce the noise of the predecessor tire.

In the course of a short run behind the wheel of the Golf on the surrounding roads, I really did not experience acoustic discomfort and still distinctly heard when the asphalt under the wheels was replaced by hard-packed snow. And I regretted that I was not allowed to ride on the tires of my predecessor: maybe the new tires are not as quiet as Matti assures?

I also regretted it on the special tracks of the training ground. Not only were Nokian Hakkapeliitta 7 tyres, but also competitor tires from other manufacturers were absent. Yes, and a set of riding exercises seemed insipid: a prosaic “snake” and a “moose test” with a short accelerating straight, which did not allow to drive up to the entrance corridor faster than 50 km / h. In both cases, the Ford Focus I got allowed me to do everything cleanly.

This Audi A4 station wagon drives... without a driver. A robot car with a rather cumbersome control system (picture on the right) is used for simple but monotonous tests - acceleration, braking on a straight line. And also - to test the effect of Hakkapeliitta 8 tires on the roadway. However, now the robot is taught to perform more complex exercises - “rearrangement”, movement in a circle and even along a winding track!

0 / 0

One consolation: I then drove three laps on an icy track in a 420-horsepower Audi RS4. Liked! Good "hold", good feeling of the car... But with questions about how these bristling tires are better or worse than competitors - to Oleg Rastegaev. He has already done a comparison test of twenty winter tires, including the new one, and at first impressions, the “studded” Hakkapeliitta 8 really outperforms the competition on ice, although the advantage is not overwhelming - and certainly not proportional to the number of studs. By the way, other new tires took part in these comparative tests, Pirelli Ice Zero, which also successfully passed the Test World test procedure and received approval for sale in the Scandinavian countries, despite the presence of 130 studs in 16-inch tires. Who is next?

The performance of the crystals in the rubber compound of the Hakkapeliitta R2 and Hakkapeliitta R2 SUV tires should be at their best on ice, where they have to work like micro-studs.

And with non-studded, friction winter tires, as I said, everything is calmer. The tread pattern has been changed (a denser network of sipes of increased width has appeared), and solid microparticles in the form of polyhedral crystals are now introduced into the rubber compound. This is something like microstuds: “biting” into the road, they increase grip on ice and even on slippery asphalt. Something similar has already been seen on Japanese Toyo and Bridgestone tires.

And what are the Finnish "microspike" made of and what is their structure?

Secret, Matti smiles. - Details will be after the technology is patented.

It is important that the crystals in the Hakkapeliitta R2 and Hakkapeliitta R2 SUV tires are evenly distributed throughout the tread thickness, that is, they will work throughout the entire life of the tire.

Production of all three models has already started at Nokian factories in Finland and Russia, and mass sales will begin in autumn. The range of sizes is traditionally wide: for Hakkapeliitta 8 tires there are as many as 59 positions - from 175/70 R13 to 255/35 R20, of which six have an H speed index (210 km / h), and the rest have a T index (190 km / h) . In nine sizes (with a landing diameter of 16 to 18 inches) there will be "puncture-proof" Run Flat tires. But the Finns promise to bring the version of the G8 with the SUV index intended for crossovers and SUVs to the market next year.

Only slightly more modest is the range of Hakkapeliitta R2 non-studded tires - 55 sizes (from 13 to 20 inches). The “initial” Hakkapeliitta R2 SUV is 215/70 R16, and there are 38 sizes in total, including Run Flat 255/50 R19 for the BMW X5. All friction “erks”, both passenger cars and off-road, have been assigned a speed index R (up to 170 km / h).

It's no secret that Nokian winter tires are the most expensive on the market, and new models will become even more expensive: studded - by an average of 10%, non-studded - by 3%. Let's wait for the results of comparative tests to find out how justified this approach to pricing is.

The tread blocks of the new Hakkapeliitta R tires (with an index of 2) have been reduced in size, and amplifiers have appeared between them, designed to increase directional stability during acceleration and braking. It is curious that in the previous generation of Erok, the treads of the “passenger” and “off-road” versions were identical, and the current Hakkapeliitta R2 SUV (pictured right) acquired its own pattern with a distinct central rib

0 / 0

As I wrote above, studding is allowed only in Scandinavian European countries, I emphasize once again that studding is prohibited by law in warm European regions! In order not to destroy the road surface.

However, in the Scandinavian countries, since July 1, 2009, a technical regulation has been in force that regulates the number of studs on one running meter of a tire - THEIR SHOULD BE NO MORE THAN 50 PIECES.

True, there is a caveat, the manufacturer can submit tests in which he proves that a larger number of spikes does not destroy the road surface.

In medium rubber R14 - R15, the number is about 96 pieces. Although, for example, the same Nokian Hakkapeliitta 8 has as many as 190 pieces, they proved that the destructive effect is reduced here.

About Asian manufacturers

These are mainly Japan, Korea, and recently China has been actively developing. There are no rigid frames here, and therefore no one limits the number of studded elements. However, Japanese manufacturers don't put a huge amount of studs on their tires and typically hover around 130 studs.

A bright representative of Japanese technology is Bridgestone.

About Russian manufacturers

The domestic manufacturer, like the Asian counterparts, is not clamped by possible regulations. Therefore, many companies set the maximum number of elements per linear meter, but if you take the entire tire, the number ranges from 130 to 190 per tire.

What affects the number of spikes?

As I have said more than once, winter studded tires have only a few tasks:

• This is snow traction
• Work in snow slush, that is, positive temperature in winter, when you need to remove moisture from the tread
• Ice handling, braking and launch assistance

So, as you understand, the spikes work only on an icy surface (on deep snow and snow porridge, they are not actually needed), and here it is logical to think that the more spikes, the better the characteristics are shown. This is almost always the case, I will not operate with all kinds of tests now, I’ll just say that if we compare the option with 130 and 190 studded elements, then the second one has a braking distance less than a meter. And it is palpable!

However, it is worth noting that now there are a lot of perfect technical innovations that have only 96 elements on the entire tire canvas. Their efficiency is about the same as that of options with 130 - 190 elements. This is because new technologies are applied here (for example, the composition of rubber, the number of sipes, the shape and fit of the spike, etc.). The stopping distance of these new products is at the level of the most “toothy analogues”, so there is room to grow.

Well, now I want to take several manufacturers and count the number of spikes on the tire, let's start.

Winter tireR13

Perhaps the most popular option, because almost all state employees wear shoes in the R13 (especially the rear-wheel drive versions of the VAZ, which were produced earlier). Since the tires are new, I will assume that all the elements are trite. I got the manufacturer "Nokian Nordman 5" we begin to count.

So, the total number is 110 pieces, as I believe that many budget representatives of this class have about the same number of elements.

RubberR14

Now, according to statistics, the R14 tire is beginning to displace the R13 representative in popularity, for example, our GRANT, PRIORA, KALINA, even in budget trim levels, already have R14 on wheels.

So let's start counting, again the same "Nokian" and again the same 110 spikes.

OptionR15

Such rubber is now worn even in budget trim levels by a large number of foreign cars produced both in Russia and imported from abroad. Yes, and our domestic cars in "full" trim levels are shod in R15.

There is no intrigue here, again Nordman 5 and again 110 spikes. So for Nokian, the number does not depend on the diameter. Actually, like many other manufacturers, such as KAMA, CORDIANT, Bridgestone, Gislaved and others.

Winter tiresR16

This is used in foreign cars of class "C" or in complete sets for class "B" of foreign cars. For example, my Chevrolet AVEO has exactly this size.

I came across the manufacturer "NEXEN", an unknown Chinese, specially took it, we begin to count, the total is 108 pieces

Big rubberR17

Such dimensions are used either on executive cars or on SUVs. The rubber is really big, let's see if there are more spikes here or not.

I got the Goodyear Ultragrip company, we start counting, the total is 130 spikes.

WinterR18

Actually, this is the last option, I want to finish on it, this is TOYO TIRES, of large diameter. Oddly enough, there are only 100 elements in it!

It makes no sense to write about the large sizes R19 - R20, yet this is not such a common rubber.

Recently, Nokian gave me a set of winter wheels from the new "collection" of 2013 - the eighth "Hakka" for testing. This rubber has been known on the market for a long time, the Finns have released more generations of wheels than the Americans of the generations of their iPhones. From time to time, the tires should get better, the grip with the road is more reliable, and the ride in winter is more confident.

Once I bought a Hakkapelita for my Volvo, then the fourth generation. But it makes no sense to compare with the old model. Much more logical to compare the feeling with what I drive now. In October I bought a Sonic and winter tires for him - Bridgestone Ice Cruiser. Both sets are studded, I don’t see the point in Velcro in our realities, when the roads are cleaned late, and sometimes the yards are not cleaned at all.

I thought for a long time about the best way to test, but I came to the conclusion that for an objective test drive I need to find at least two exactly the same cars, put them in different tires, and go to an icy lake or race track. Alas, I don’t have anything like that at my disposal, so I’ll just describe my feelings: I drove the “bridge” for almost the whole winter, and one month on the test Nokian.

As the creators of the wheel themselves say, they have been working on the new generation for more than four years. “Our idea is that a real winter tire should perform optimally in all climatic conditions, whether driving on ice, snow or slush,” said Juha Pirhonen, Head of Product Development at Nokian Tires.

Perhaps the main difference from previous models and from competitors, Nokian calls a completely new way of studding tires: the concept, called Nokian Eco Stud 8, includes a new type of stud (the so-called "anchor"), and a special "cushion" under the stud, made from a special rubber compound. This layer improves stud performance and softens contact with the road. The studs are distributed evenly over the entire tread surface in such a way that none of the studs overlaps the other. Yes, and the spikes themselves have become more - in the "eight" there are 190 of them, while in the previous model - 130 per tire. I wonder how many competitors have them?

As for my personal impressions of driving on the new rubber, I can single out two of the most important: low noise level and really good grip. During the test, I drove out of town, where the roads are not cleaned at all: just a frozen primer, rolled down to ice. Not a single skid, the car was not driven to the side even once, although the Aveo does not have a course stabilization system. Particularly strong impressions were during the recent "snow porridge" on the roads. I think it was March 15th. The temperature was around zero, it was snowing, the ice began to melt, which formed huge puddles and a snowy mess. Every minute, a freshly washed car was doused with mud from under the wheels of neighbors downstream, which is why I didn’t see anything for a few seconds. I had to maneuver and brake in front of sharply slowing down cars in front of me, losing visibility, other drivers first of all put pressure on the brakes without looking back. On that day, I drove almost 200 kilometers in Moscow and the region. I don’t know what saved me then - my own experience or new tires, but I think it was both.

Many consider the main disadvantage of a studded tire in the city to be that the quality of grip on clean asphalt is much worse. For me, the biggest inconvenience of studs on asphalt was their noise. Bridgestone, indeed, turned out to be very loud, which cannot be said about Hakka. It would be a pity to give it back.
