The secret lab and test new Nokian tires Hakka Green 2
Of course, all the way from home in Moscow to the ground in the Nokian Tires I was imagining how I'm going to burn the fuel and to wash the tires on the test track the size of the airport. Hundreds of precise instruments to record the condition of the tires as they warm up, wear, cooling, wetting and so on. And feel that has not fixed the devices with every fiber and nerve endings, and then to report the change of properties of tires the main tire on the Finn. In the process of thinking about their future career after polygon Nokian in Tampere, I got around to test-pilot of the formula 1 and just was choosing between offers from Sauber and Ferrari, when harsh reality stepped on the throat of my Swan song Finnish boots Reinot.
If you think to draw and to construct bus is easy, you are mistaken, where every groove and notch verified by hundreds of experiments and test runs. And the secret lab, though show the journalists, but taking pictures is not allowed. And talking about it can only whisper to the Chinese konkurenty not found out.
In the laboratory many stalls with weird Finnish names, in the stands above the tyres are happening lewdness designed to test and explore, and then nadawat hands of engineers and designers and get to redo everything. They were prohibited to take photos, so a verbal description.
On the stand is like a huge drum checked the features of the structure of the tire. Tires spinning on the drum, long and dreary, sometimes explode, so the whole structure behind bulletproof glass. Here are checked it is the Assembly of the tire, and not as grinds protector (check for wear is a different story and test on the range).
There is a stand to measure the static pressure of the stud on the tyre surface and the test for measuring the resistance of rolling — here at speeds from 1 to 320км/h, we study the behavior of the tire and the action of radial forces.
Individual 'crazy test' is designed exclusively for the American market — the steel finger presses on the tire and on the same stand, measure lateral pressure — the force which is required to tire was beaded in pressure along the wheel hub. Thus emulation of Parking close to the curb. The demand for tyres from the Americans are completely different.
They only care about mileage tire, if I understand correctly — there is no culture of comparative tyre tests for various characteristics, there is only a standard that the bus should conform to that in General only means that the tire is guaranteed to pass a certain number of miles (e.g. 600 000). Noise, rolling resistance, length of braking distance and other regalia in the form of certificates of American consumers do not care.
This secret object had suddenly ended, and we came to the last booth which is measured by the maximum pressure that can withstand the tyre.
The party selected a random tire, and pumped with water until the tyre bursts. It turns out that everyone with a minimum spread explode on 24-25 atmoshere so precisely and clearly defined manufacturing — as an engineer I was very impressed.
As a result of all these inhuman tests and examinations appears the tyre perfectly meets the specified requirements for efficiency, reliability, noise and grip.
The new Nokian Hakappelita Green 2 was created specifically for difficult climatic conditions and one of the most important and useful for the Russian climate characteristic is the resistance to hydroplaning and performance on wet pavement.
The Coanda effect is a property of liquid to change its direction depending on the shape of the surface — there is used fully, it's like in Formula 1 or in aircraft. All furrows and grooves on the tire is adjusted with accuracy to the millimeter just to take the tire high water.
The curved design on the blocks of the tread reminiscent of a ramp, in the inner shoulder area of the tyre, directs and accelerates the flow of water from the longitudinal grooves in the transverse grooves. The excellent properties of protection against aquaplaning persist even when the tire wears out. Aggressive pen grooves cross the ribs in the Central part of the tread, effectively accumulate the water and direct it in the longitudinal grooves.
The outer shoulder of the tire, consisting of pieces of the tread is firmly connected, provides a solid contact with the road. Thus feeling more accurate and stable driving and low noise. Open tread pattern and a new innovation on the inside shoulder of the tire increase traction on wet pavement.
Improve handling and ethnostyle succeeded to achieve thanks to a new contructii steel cord. Each wire consists of two strands, twisted together. The diameter of each filament is only 0.25 mm. is approximately 110 twisted pairs for 10 santimetrov. While the strength of the same wire long enough to use it as a tow rope.
But enough theory, let's get to practice. First test on public roads in a convoy of cars of a Golf class
Can't help but notice how much I liked the diesel Volvo — trailer in front of the car, and stopped to touch the gas and brake, later discovered control strip and stopped to touch the wheel.
However it turned out that the yellow temporary marking system does not understand and the band does not hold, so the most interesting place had to interrupt the discussion, especially because of the turn change machine.
The verdict is this:
Mercedes and Citroen — the rubber is very quiet and has a relaxed leisurely place
BMW and Honda tires noisy but allows you to move around
Volvo Golf rubber average noise, but in General comfortable and if you want you can make a row
Small summer on the ground all clearly and even cones are marked with special places. Later all the cars will go to Ivalo winter range, and until all the tests occur in the vicinity of the city of Tampere. In Lapland in the winter will work the same team and the same machine, this allows as close to real life conditions test operation and does not allow 'to zamylilsya' view experts. Over the past year so it was tested 15000 20000 winter and summer tires.

Test the behavior of tires on wet pavement and puddles.
The first plot is intended for comparing the properties of winter and summer tires on wet roads: acceleration to 60 km/h and braking on wet pavement.
this test interested me most because it seemed to me too strong a difference in the settings of the ABS on the test cars
(-)when braking to "brake to the floor" my results on nokian hakka green 2 fit about 20 meters.
(-)when braking to "brake to the floor" my results on the worn winter tyres continental were placed approximately 40 meters.
(-)when braking "in Polidori, trying to the ABS didn't work" my results on nokian hakka green 2 fit approximately 15-18 meters.
(-)when braking "in Polidori, trying to the ABS didn't work" my results on the worn winter tyres continental fit about 25 meters, but to achieve this it was very hard because the ABS was very sensitive and worked almost immediately
I don't think there was any malicious intent, but rather just the fact that the cars rolling. but I felt like a real Explorer tires :) Well, the conclusion is that the summer tires in the summer slows down and behaves in a pool is much better than winter, I think, is obvious.
The second test was aquaplaning: acceleration to 40 and acceleration in a puddle
(-) aquaplaning on nokian hakka green 2 in a mode "gas in a floor" my feeling started somewhere at 70km/h
(-) aquaplaning on worn to 4mm nokian hakka green 2 in a mode "gas in a floor" my feeling started somewhere at 55km/h
After exercise and water procedures, we showed a fighting humanoid robot, which inquiring minds have discovered in the back yard behind the hangar.
It is a fully robotic car without a driver. My first thought was the tests with overloads are not sposoban people, something terribly dangerous, fire, explosions, and copper pipe. But all is simple — it is used for those tests where people, even trained Finnish, quickly turn green and go crazy from the monotony. ie 120 rounds on the ground at the speed of 40km/h is his problem. The control system provides the accuracy of 1 cm in the conditions of landfill is more than enough.
But in the future we plan to use this robot to test handling and comfort.
The system allowed to automate any vehicle, and the control can be proizvodite of the body "gazelles" equipped game console
But one of the biggest tests of tires occurs not on the ground or in a research lab!
Some genius from Nokian Tyres, and probably got a generous bonus, selling management the idea of using a taxi as a test fleet for a prolonged and ongoing studies of the tires. At least 100 taxis every day travels to Finland and shorkatsya tires Nokian. The measurements are carried out every 5 000 km and sometimes more often, averaging one car a year, change at least 2 winter and 2 summer sets of tires. In the process fixed as many factors of wear. Spikes, their number and condition, as conducted in the process of operation of various types of rubber compounds and different design of the tire tread, cord. Also fixed the status of disks and their behaviour when operating with different tyres and rubber mixtures. There is regular checking of wheel balancing and changing this balancing during operation. According to the monitoring results of all these dozens of options and hundreds of combinations regularly sostavlena report. And then rolled the tires of different wear travel to R&D for research under a microscope and interrogation. Everything counts: tread, sidewall, the design of the grooves and checkers protector — rolled tyres every 2 weeks taken to a secret bunker whose location is only know the main. In short, all very, very seriously!
The result is a tyre that is quieter, more efficient and safer your predshestvenniki. We save gasoline and money on the tire and a little less worried about the safety of his family. As always, the world becomes a better place.
Well, probably the most important for those who decide to buy the new model — pay attention to marking. The fact that through the use of an advanced rubber compound was able to dramatically improve the performance of rolling resistance and braking. Therefore, when the same design and the advanced tread pattern of the tire are labeled AA, while normal BB.
Here it is, supershine on stamped disks
The range of sizes of the new Nokian Hakka Green tyres 2 are presented from 13 to 16 inches and is designed for small and medium-sized family cars (B and C segments). The most common speed rating T (190 km/h) and H (210 km/h). The range also includes five frame sizes (including the popular size of 205/55 R16) with the highest index And wet grip and rolling resistance under the European tyre label.
Key markets for tyre family, Nokian Hakka are Finland, Scandinavia, Russia, Belarus, Kazakhstan. Bus will be available to end consumers in the spring of 2016.
Well, in Finland well :)
and very safe...
Oh. too bad we can't take Camu rental — samples))) I really liked how Sava brakes. even with the ABS it works better. so much time saved, when I thought I had all be an accident. want this option not to lose.
At the prices of Kama cheaper, sometimes very significantly, I Huck Greene took just because she's in one of the shops for a penny more expensive than the Kama is action which, because it is more a freebie I have never met.
and the prices?))) I mosavtoshina watched Kama you are all worth a penny compared to our prices)
Don't even know the difference is not noticed, Jaca softer, and feel wears out faster
I have hakkapelitta 4 Russian production retreated 4 winter, then summer and winter. I bought it the first two winters, without any complaints, then the number of broken spikes became evident. After the 4th winter of thorns was so little, that I kept the tires and in the summer, is to finish. Because of the visible tread wear did not exist. The condition of the rubber itself was perfect. So after summer, I still half of winter left. By the time I bought the second car.
But this winter rubber in the summer bought the hack green instead of the Kama, skated for about two summer seasons, wear about the same as the Kama, maybe a little faster, the rest of the striking differences with the Kama I have not noticed.

What the heck marketing. In the same hack 4 for me the main advantages is the stability and permeability and durability of the spike. How these characteristics affected Nordmann, is the question. Tread wear on the Hakka did not notice until I allowed her to flow in the summer, when the spikes almost nothing left, and in the winter to keep the road.
how many millimeters remains after 30000км with moderate driving? whose production tires? I have 2 experiences: 1) China, faded to almost zero for 2 years (I year on average passing 15 thousand); 2) Slovenian — 2 years, I would say that it is almost erased, if not off pieces.
I now want to probyvat Russian "foreign cars" of a famous brand, but I'm afraid what will happen as Slovenia. then, too, a daughter of famous brands.

The Nokian rubber is good in the rain great grip, but wear very fast on the drive axle over the summer, 37000 went down to 3 digits
wear on the front drive, but the rear standards. Season 3 and 6 only. true mileage 10 thousand. to replace for the winter.
Not to go to work just not as bad as in the past, but work the ass — packing the tube. The dachas in the summer almost every weekend, so anyone, I think it often.
I have a friend who works in transport. His car's mileage for the season is almost 60000км. And I, for example, go mostly to the shops, family and villas, rarely to work, I have a 60t.km for a couple of years only accumulates :)

Ran a different tyre this brand more than 150000 km and not a word can not say bad, what about the winter, what about summer.The cars were different.
Nokia does not know how to do summer tires. Curve and dead... I think for her even cracks in the pavement is destructive ;)
PS: But who is not satisfied sinacom, I understand. Good grip, and 5 and 7 with the bump — apostolicity on top.
It's hard to read, then writes from the woman's face, then from the persons of men, but for those not in the same sentence writes like a man, then as a woman and again as a man. In short, the author of which is not adequate for!
On dirt, wet dirt road with ruts, wet grass and pine needles — are getting tired immediately, and not go. Exactly. Like most "cool" of "inbrands". Bullshit rubber. Kama 217 and that this "shit" is.
if the rubber is soft and quiet, then go to her max. 3сезона...it's just somewhere if a lot of something little ...and it does not happen so and brake. in number, and softly rolled and if the choice is between Russia and CHINA it is in my best Russia from 3000 -3500
Hakka green was probably 40 thousand, two seasons quiet ride. I think that is enough.
Skated three seasons (hack green) — did not like. 1. All the same, harsh rubber, when injected into a puddle there is no anticipated effect machine with easy throws. 2. Noisy. Of the benefits that only in dry weather it holds the road perfectly. After the hacks took Kumho — satisfied and happy with everything ...
Yes, with a dimension it is. We was between these options in the size 205\55\16, Price segment they have one, but what is better question.

But interestingly, went for the Nokian Hakka green is, in principle nalasa rubber, but then moved to the continental premium contact and realized that Nokian car could not realize the potentials of upravlyaemosti.Who thinks about these brands and models? Nowhere is the correct answer not found)
Nokian Hakka Green and Conti Premium Contact — sensitive segments across the tire. Hakka Green is available in diameters from 13 to 16 and more focused on comfort, aquaplaning resistance and cost-effectiveness. As for Premium Contact: available to 17 inches (could be wrong) and attention is focusing more on handling and stability on the road. In this segment of the model is the Conti Eco Contact.
I really liked Toya (summer). Winter Nokian Haka. Finnish and openly holds the road better than Russian.

Now (as in many other fields) tires make a very short-lived. Yeah, I guess they are soft, quiet, well disperse water, and win in the tests, but I have worn for two seasons. Although I travel a little, to work for example, I ride the subway. And I'm now willing to believe that a season can be compacted tires. What the manufacturer profitable — and faster to shop for new tires will come running.
I remember the time when I go on a single set of five seasons. Five, Carl! And went every day.
The Nokian tires I'm disappointed. In the furnace, let the other suckers Spud, to buy more of their products there is no desire.
My friend at the time drove a three year old Audi from Germany, with a mileage of about a hundred, so there was almost erased to zero tyres (if I'm not mistaken Conti) — and this is a new spare tire from the factory. Date of manufacture of the same. This is a normal result. The truth was that long ago.
I wish you all: Buy good, good tires, not the clay.
Depends on all-wheel drive and riding style! I always sat with on the long drive wore. Total mileage 200tys to 10 years. Mostly local and regional roads with frequent turns, went 110-160 km/h usually.
1. Nokia of hakkapelitta 4, went with buying a car, rolled for 1/2. Half the spikes in place. Sold with them
2. Yokohama geolander, changed at 110 thousand km, and rolled 3/4
3. Michelin primacy 2, Cathal remaining 90 thousand, and sold. rolled for 1/2. Sold with them
I don't know.I have a wife already the third season goes.protector fit into the norm.

Nordman 4 harden? burning some you got. This is the softest rubber I ever saw. And its softness in the cold has not changed from the word did
I have on my machines are Green, Hakka4 and Hakka5.
Green - when he first shod, could not understand what happened to hodowli, the car was as the barge, to spin the wheel and half a second waiting for the reaction, on the track floats, always have to catch. The second minus - all cracks Bach on the head. Really feeling that you go not in the car and in the car by rail, and large gravel noise is in the cabin. On smooth asphalt I agree - silence. Departed season 3, after Hakka i3 with 620 treadwear index of anything. Rubber extremely dissatisfied
Hakka 4 in the first winter, feel the excitement, really no difference that under the wheels, keeps perfectly, the brakes too. Second winter - a little worse, but quite on the level. Third winter on the front wheels were about a dozen (!) spikes. The rest... no, not escaped, they are broken off, now either stick the cap housings spikes, or they broke off and seen the holes, their remnants... Sucks.
By the way, this winter two very dead wheel was replaced by Nordman 4. A conclusion based on them - хакка4 no studs holds up better than the new нордман4 with spikes. Quite expectedly, he dubeet in the cold, the rubber compound is totally different. So don't get fooled by stories that this is the same Hakka, only discontinued as Hakka and produced under the brand name Nordman.
Hakka5 until it shows itself more or less normally. But the mileage she's small enough. too early to draw conclusions
In General, for me personally the picture is clear - if winter Nokian worth the money (though not enough walks), then the summer, excuse me, shit
Nokian? Yes, God forbid! Expensive.
Recently in the Main road tests of the Nokian winter against Continental. Guess who won? The Nokian braking distance was longer. Cool tire lost cheap.
And to pay for the name, it makes no sense.
don't buy a second one I first had, was particularly impressed by the rupture of the tread radius, tread into two halves at the end of the guarantee and depreciation of 25-30%.and read paid article unpleasant
