From the first day of July 2013, a new legislative restriction on the studded tires was introduced, or rather, the number of spikes on their protector. Now in the Northern European countries, winter automotive "shoes" should have no more than 50 spikes per meter rolling wheel.
In the legislative restriction there is one reservation (Lazeka for tire manufacturers). If they prove that tires with the former or increased number of spikes do not apply additional damage to the roadway compared to standardized tires, their production will be officially allowed.
So, what did the new restriction affect the tire products? Let's look at four new tires from different manufacturers, because it turned out, each of them went to his way ...
Modernization of spikes
The German manufacturer decided to update the design of the spike in its popular model ContiCecontact and give it (spit) a new name - "hybrid". Main changes are associated with the advent of a new core section. The former X-shaped gave way to rectangular cross section. The new core has become more compact and now has concave side sides.
Thanks to the optimization of the design, spike weight decreased. And this, in turn, led to a decrease in mechanical impact on asphalt coating and a decrease in the speed of its wear.
However, German tires paid attention to the durable landing of spikes. Now they are glued on the basis of another technology. The inner part of each spike is covered by a special reagent. After its contact with the rubber mixture there is a special chemical process. Thanks to it, the spike is reliably fixed in the tread pattern.
Due to the new gluing technology company Continental intends to solve problems with the loss and turning spikes. Around them there are special grooves for ice lead. Technology received name Crushed Ice.. According to CONTINENTAL test estimates, this solution reduces braking distances On the icing road by 10-13%.
Continental noted that IceContact with old spikes were removed from production lines. Now the remaining reserves are now, but soon in the markets will appear winter tires With a new spike design.
Protector Improvement
To improve the operational characteristics of the tires, changes were made to the protector pattern. On its inside used new stepped lamellas. Their main task is to improve the clutch on the ice track / snowy road during disks and braking.
On the outside are used wave-shaped lamellaes. They improve controllability and make the car more stable and responsive when performing various maneuvers.
Continental specialists also noted that the asymmetrical protector pattern ContiCecontact contributes to uniform and slow wear.
Harsh winter conditions is not a problem
For more efficient work your new tires when low temperatures German tires added a special synthetic softener into the rubber mixture. Thanks to this, the tire component can save an acceptable elasticity even in very coldy.
Replacing IC7000.
SPLIKE-01 studded winter tires is a new representative of the BlizzaK family. The tire replaces the IC7000 model on the market and has several new technical solutionswhich favorably affect its performance characteristics. It is represented in 60 sizes (landing diameter in the range of 13-18 inches) and can be installed as compact carsand on SUVs.
Advanced flexibility protector
The novelty has a tread pattern of a V-shaped type. In its central part, the edge of a zigzag form with lamellas is located. It provides a comfortable and secure Management On a dry road.
One more a distinctive feature The tread is V-shaped channels. They decide important tasks In winter bad weather - weighing a snowpall, dirt and water, allowing you to maintain control over the machine.
To improve the grip of rubber with an expensive in severe frost, the protector was made more flexible and elastic.
Bridgestone specialists paid attention to and enhancing the traction qualities of their new items on the snowy road. To do this, special teeth were made in the blocks of the shoulder zone.
The microporous structure of the 5-mm top of the tread layer contributes to the absorption of moisture and simplifies the task for drainage channels when driving in deep puddles.
Audged question
As in the case of Continental, Tirenits from Bridgestone made a bet on the new spike design. The form of their upper part has changed. Now the spikes have a rectangular tip. Due to this, the coupling characteristics on the ice are improved. New spikes allow tires more effectively cling to an ice road. Against the background of IC7000, the novelty Spike-01 is much better "biteling" into the surface of icing roads.
In order for the pressure of the spike core pressure is small, the X-shaped sample is used in its end. Thanks to this solution, the degree of ice vendibility remained at the same level.
The X-shaped sample effectively works in a pair with grooves located around spikes. Together they accelerate the diversion of the icy crumb from the spike and increase the efficiency of its work.
Another curious decision of Bridgestone specialists is the use of sockets in the form of "mushroom" for planting spikes. According to Japanese shinniks, this configuration contributes to its optimal consolidation in the protective.
Another way
A studded winter tires of the Hakka family is ready to surprise motorists. The eighth development of the Finnish manufacturer is represented in 59 variants of sizes. The landing diameter varies within 13-20 inches. One of the features of the eighth Hakkapeliitta is an extended warranty.
After receiving damage during operation, the Finnish manufacturer promises to produce one free replacement (if you can not repair) or repair the purchased bus.
More means better
The Finnish manufacturer decided to take advantage of the "Lazeka" existing in the legislation. At the same time, Nokian experts managed to set more spikes on their new tires than before.
Of course, to meet the new standard, the fins had to thoroughly work on the design of the spikes. As a basis, the details of the hex form from the seventh Hakkapeliitta were taken. Their height was reduced by half a million, while branded pillow ( Eco Stud.) Under Spikes became noticeably thicker.
The spikes themselves were made more compact and easier. This allowed the Finnish manufacturer to prove that they new tires It does not have excessive pressure on the road surface. During the tests on a special landfill, it was revealed that rubber with new spikes wear a road by 12% less than established in legislative restriction.
So that new spikes have become stronger to "sit" in place, was applied. updated protectorconsisting of two layers. Its inner layer is distinguished by increased rigidity and durability. It promotes improvement currency stability and uniform wear of rubber on dry trails.
New lightweight and compact Nokian spikes sets only at its own factory.
New protector drawing
The tread pattern was developed by Finnish specialists from scratch. They did not borrow nothing from the seventh generation Hakka-tires. Despite the familiar V-shaped external executionThe directional pattern includes several unique solutions.
For example, the fins seriously broke their head over the optimal location of the lamellae and blocks. As a result, they managed to achieve good result In the field of coupling characteristics on ice and a snowy road.
In addition, the Hakkapeliitta 8 protector has an increased number of smaller blocks. Due to this, the number of protector grooves has increased, and when the fifts have an opportunity, the possibility of more free spikes have appeared. As a result, they began to be located farther from each other, if compared with the seventh generation model.
More compact sizes Blocks reduce tire heating while driving. Due to this, their degree of wear resistance increases.
Central block checkers were merged together for better course stable and controllability with complex weather conditions. As a result, the rigidity of the central edge increased.
In the protector of new tires, you can find open shoulder areas. They were made by the famins for more efficient tread self-cleaning when driving on a loose snowy road.
The cerebral package of increased rigidity is based on the tires. It allows the tires to maintain its original shape even when driving on great pits.
And one more important point. In the rear of the checkers, braking amplifiers appeared. According to Nokian, they improve the braking characteristics on any types of coating.
Game according to the rules
The French company introduced the long-awaited third generation X-Ice North. This season, the novelty will be offered in 31 sizes (15-20 inches). Next year, the French promise to bring another 35 sizes to the market (14 of this number of brand new).
The third X-Ice North responds to the Scandinavian requirements for OshIpovka. With the roadbed, no more than 50 spikes on the rolling meter contact. Unlike other tire manufacturers, Michelin decided to neglect the reservation allowing the setting of more "tooth-out" parts. True, for this, the French had to work seriously.
New technologies and design solutions
Michelin patented new technology called Smart Stud System. Its uniqueness is as follows: the protector is made of special rubber mix with thermoactive properties. It is it that allows French tires to meet all the established requirements.
When the temperature decreases, the solidity of the mixture increases, and when the temperature rises, it decreases. Thus, the tire has improved operational characteristics on ice. Due to the adaptation of the rubber mixture to the temperature on the street, the force of priming the pink of the surface of the icy road is also adjustable.
It is worth noting that at -10 degrees the hardness of the inner part of the rubber increases 20 times, and at -20 degrees - 30 times (compared to tires manufactured by standard technology).
Another patented know-how is. Its work is based on special wells surrounding every spike.
Michelin noted that the brake path of the novelties on the Obellen Road became shorter than 10% compared with the predecessor model. The positive result was achieved, despite the reduced number of spikes that play a big role in brake characteristics on ice. Thus, the French are reporting the effectiveness of the new technology.
New shape of the hull of thorns
For the third generation of tires X-Ice North was developed new Schip. It has a former round section, but a completely new conical shape of the housing (the third patent of Michelin). In particular, the shape of the cone was attached to the floor of the part. Another new solution was the increase in the base of the spike per millimeter (from 8 to 9 mm).
In the aggregate, this has a positive impact on the reliability of its fixation and the service life. The French noted that these characteristics were increased by 25%.
Not forgotten about broken domestic roads
In the manufacture of new tires, Michelin has given special attention Their strength and durability indicators. To do this, the logging frame uses a thread with a "twist". They are distinguished by increased rupture resistance.
The sidewall Michelin has been upgraded and strengthened for its lower exposure to punctures and cuts. Plus, the tread blocks have purchased a stepped look, and the number of tetter sectors increased by 15%. All this gave a tire more patency on snow barriers.
Other solutions to MICHELIN specialists
To increase resistance to the aquaplaning and slashplaneening Michelin modernized the system of drainage grooves. Changes were made to their location. The grip on the wet track is also improved thanks to the new mixture. FLEX-ICE 3 contains an enlarged silica. The amount of artificial and natural rubber was also optimized.
Today, the automotive market offers a large selection of tires of the most detailed destination. It is very difficult to say which firms can be considered the best. Each tire has its own positive and negative sides. Therefore, when you select, you must pay attention to the parameters of the product, as well as on the name of its manufacturer. Each driver prefers to use rubber, which suits him most. Therefore, for comparison, the following are small descriptions of rubber of various manufacturers.
Nokian Hakkapeliitta 7 SUV
Finnish tire made by newest technology, installed on SUVs. Won great popularity in the Russian market.
Tires do not make it difficult to control the machine. They are moving freely on bare ice. Tightly planted spikes make it possible to overcome loose snow. Calculated for long-term use.
Disadvantages:
- Wheels, running several seasons, can be locked.
- Too high price.
If you compare Bridgestone tires with Nokian, then definitely some of them are better enough. Riding on "Velcro" is somewhat different from the ride on spikes. The choice between Bridgestone and Nokian depends only on the driver's preferences. According to the characteristics, they are almost the same.
Goodyear Ultra Grip Ice Arctic
American tires made of soft rubber, using Multicontrol ICE technology. Ship design has a specific shape. Three angle allow you to improve controllability, and increase car's permeability. Machine freely moving along snow-covered roadmay ride my wet asphalt.
Bridgestone, Michelin and Nokian - What is better?
The Japanese company Bridgestone took a small batch of journalists to the autopolygon, in order to soberly assess the stated superiority of new models in action winter tires. Namely: Bridgestone VRX and Bridgestone Spike-01. It should be noted that the Japanese tried to please all consumers. Model VRX with typically Japanese "sticky" protector. That is, for the most bold motorists. The second novelty from Bridgestone is represented by the studded SPIKE-01 tires. It is for those drivers who do not want adventure on the road. Security appreciate, in general.
At the presentation, representatives of Bridgestone visually reported to journalists the benefits of their new products. Relative to other brands. Namely: the result of the Bridgestone test in Japan and Moscow is demonstrated.
That's what it turns out.

Wanting to purchase tires for your car with the best combination high Quality and optimal priceEach motorist faces the complexity of choice.
ATTENTION! Found a completely simple way to reduce fuel consumption! Do not believe? Auto mechanic with 15 years old also did not believe, until he tried. And now it saves 35,000 rubles per year in gasoline!
Car accessories market offers wide assortment seasonal tires From different manufacturers, therefore, it is not easy to stay on one brand, even when it comes to leading suppliers.
To simplify the choice for motorists, consider more details and the benefits of production of industry leaders - Michelin and Brigestone. And on the basis of the information provided, we define what is better: michelin or brigestone
A little about competitors
French company-manufacturer of automotive tires Michelin and its Japanese opponent BRIGESTONE company are two recognized leaders This segment of the automotive industry.
However, disputes about who takes up the championship do not subside. Moreover, independent research companies are involved in their resolution, conducting analysis of durability, strength and product costs. At the same time, the opinions of motorists are divided in terms of choice summer rubber For your car.
What is better: Michelin or Brigestone Summer?
To answer the question about Michelin or Brigestone better in summerIt is worth considering two main aspects. Namely: specifications and style of driving owner.
Comparing the two most popular tire models technical characteristicsTheir, as a rule, is subjected to three main tests:
- Riding under road track.
- Passage of the racing route.
- Consume payment by car fuel.
In determining which rubber is better: Michelin or Brigestone, two new items took part, which are used for sports cars, and for daily trips by car speeds. We are talking about rubber models Bridgestone Potenza S-04 Pole Position and Michelin Pilot Super Sport.
Immediately it is worth noting why among the two most popular models Brigestone, Potenza was chosen, and not Turanza.
With the advent of a new model, when answering a question that better Brigestone Potenza or Turanza, car enthusiasts are increasingly choosing the first option due to the best handling and quality of the stroke.
Test traffic test
To compare the Michelin and Brigestone tires of the specified models, they were driven along the road track, longer than ten kilometers. Special sections were created on the specified section of the road, each of which imitated the conditions when overcoming the highway, country roads, urban streets. At the same time, the type of road surface is constantly changing. There are segments with a new asphalt, sections after partial (patch) repair, smooth and coarse-grained concrete, coating, imitating bridge and ground roads.
Thus, there is a real opportunity to check not only the degree of tire clutch with different types Road covering, but also test them in the modes of different traffic (riding in the speed highway, overcoming the country road, movement around the city).
Also, such a variety during the passage of the track shows the level of controllability of tires, the degree of comfort when driving and noise level with different coating and speeds.
When passing this test stage, determine the best between Michelin or Brigestone Summer (Potenza) is extremely difficult. Both contestants show excellent handling, and also give a feeling of complete comfort with any type of road.
The only difference was the type of reaction to the driving movement. Brigestone Potenza rubber at turn reacts smoothly, gradually leading the machine in the right direction, while Michelin reacts as quickly as possible and even sharply. At the same time, the softness of the move Michelin allows the car without difficulty and shaking to overcome minor irregularities of the pavement of small and medium-sized format, and gives only a slight push when overcoming bumps of large sizes.
Brigestone, when entering the plots with small bodies, behaves tougher than Michelin, and in the case of large potholes, on the contrary, completely absorbs the energy of the collision.
With regard to noise level, both models behave on the track equally. With a minor speed of the course noise is absent, and with increasing speed, minor (within the normal range) appear, but clearly distinguishable noise.
Test racing tracks
This stage of test seemingly not mandatory for tires if they plan to use only in everyday ride. However, to compare the limit of the possibilities of any product is necessary, precisely for this reason, both models have driven along the track.
The length of one turn of the racing tape was 500 meters. With its passage, tire maneuverability was checked during rapid angles, rebuilding from a number in a row and even the congress from the canvas. Moreover, all the tests took place at two states of the canvas: dry and wet.
In conditions of dry track and high speedsTires brand Michelin, due to the rapid and sharp reaction to any steering movement, show top scores in maneuverability, and also give a feeling full confidence In the clutch with the road. Brigestone also makes easily maneuver and gives a sense of driving control, however, by speed driving, for a few seconds behind the rival.
As for the passage of a wet track, Michelin also confidently hold a clutch with an expensive and perform all the maneuvers given by the driver. Despite the smaller sense of control of the road, Brigestone also showed beautiful maneuverability and response speed on the steering movements, there are nothing disturbed from driving on a dry canvase.
Analysis of fuel consumption
In this test, the definition of the better runs according to the results of overcoming the segment of a ten-hour long path, which will have to go in three velocity modes corresponding to the motorway, highway and country road. At the same time there are signs of the need for stopping and traffic lights.
According to the test results, the difference in fuel consumption when using tires each of the companies amounted to 150 milliliters. Michelin tires were less waste, their consumption was 10.45 liters per 100 kilometers. Brigestone tires, respectively, showed a result of 10.6 liters per hundred kilometers.
Thus, the tires of French manufacturer Michelin., products japanese companies Brigestone show the highest results. Starting equal friend With the other, the data bus companies largely exceed the products of other manufacturers of the automotive industry, which explains their popularity among consumers.
RESULTS
Summing up, it is worth noting that according to the technical characteristics, both competitors are significantly superior to the other manufacturers and go shoulder to the shoulder with each other. And the choice of one or another type of tires, more depends on the style of driving the owner of the car.
So, if the motorist prefers a quick ride by car, which performs all maneuvers at the easy turn of the steering wheel, it is worth stopping your choice on the tires of the Michelin brand. Due to its maneuverability, a sharp reaction and an excellent hitch with an expensive, they will provide fast and safe ride On roads with smooth or fine-grained coating.
In the same situation when comfort is important for the owner of the car, regardless of the type of road surface, it is worth choosing brigestone bus. Product this manufacturer It is an ideal balance between the comfort of driving and maneuverability, while maintaining an excellent grip with an expensive under any circumstances.
Tire Rack: comparative Test Tire Michelin and Bridgestone size 225/45R17 (2011)
Tire Rack suits the "Battle of Titans", comparing the newest tires of the Max Performance class from Michelin and Bridgestone.
The battles battles are usually called the epic confrontation of truly strong rivals, so that this phrase is quite suitable for describing the new Tire Rack test, in which the two newest Tires of the Max Performance class, as well as two models that have long been considered one of the best in this category. Over the past 10 years, the MAX Performance tires have achieved a striking level of development and now provide exceptionally reliable clutch and dry, and on a wet surface, but at the same time combine their driving qualities with a civilized character that makes them suitable for use in everyday life. Many today's supercars go beyond the gates of the factories, being "shovel" in the Max Performance tires, which are included in their primary equipment, as this rubber allows maximum to use all the power of these cars immediately after purchase. And besides this, many sports entry lovers themselves put these tires on their cars that are used daily.
Not so long ago, two true Titans of the tire world presented their new models of the Max Performance class - Bridgestone Potenza S-04 Pole Position and Michelin Pilot Super Sport. Both are long-awaited replacement for tires that have already become popular and proved their worthwesters. But which of the new products is better? To find out, the Tire Rack experts compared the behavior of tires in the real world and on the racing track, and the top tires of the Max Performance - Continental ContiExtRemecontact DW and Pirelli Pzero were selected as opponents of two newbies. Tire Rack notes that Continental not so long ago headed the rating compiled by buyers of tires on the company's website, and Pirelli has always shown high results in tests and since its premiere in 2007 managed to enter factory configuration Many of the most powerful supercars.
Used in tests coupe bmw. E92 328i (2011) with discs of size 17x8.0 inches. All tires were taken in the amount of 225 / 45R17 with a full protector depth.

Road Test
The road track is 10.6 km long consists of areas that imitate the conditions of the highway, the roads of local significance and the country road, which makes it possible to test tires and on the highway, and at the speed of urban traffic. In addition, there are sections of smooth and coarse concrete, as well as a new asphalt and coating after patching. This allows you to determine the noise level, comfort, quality of the stroke and handling in everyday life, as the conditions are identical to those that come across during the usual trip to work.
None of the tires became disappointment in the road test, and everyone could provide good handling in conditions of ordinary life. Regarding what tires are better, opinions were divided between Michelin and Bridgestone. Both tires quickly and accurately react to the turns of the steering wheel, but the Bridgestone reaction is felt more linear, and the power of the lateral injection in turn increases gradually, whereas in the case of Michelin it happens more sharply. The verdict is: both tires are excellent, but behave a little differently. Pirelli also react clearly and consistently, but not as fast as Michelin and Bridgestone, and Continental has taken the last place, as they are felt less informative, and experts note that there is a pause between turning the steering and their reaction.
But this deficiency of Continental allowed them to break out in the test of the quality of the course, and these tires are best absorbed by the sharp joints of the coatings and provide a smooth stroke on the "sled" asphalt. Michelin copes well with a small and medium-sized bumps, but the driver will feel a small push at the road to great irregularities. Bridgestone is a bit tougher than Michelin, while driving on a little irregularities, but they better absorb the energy of the blow when it gets into a large pothole. Pirelli is quite a bit behind the rest, as they were slightly less comfortable.
The noise level of all three tires can be considered quite acceptable, but the best has become continental again. Michelin and Bridgestone lost Continental, as they make a quiet, but distinguishable noise as speed increases. Pirelli buzz a little on high speed, especially on asphalt.
Tests on the racing track
Test track (the length of one circle - 0.5 km) includes turns of 90 degrees, congresses from the motorway, as well as several bands to determine how tires behave during the rebound. Pilots are driving on dry, and on a wet surface to evaluate traction effort, responsiveness, handling, etc. During emergency maneuvers.
On the test track, Michelin is immediately knocked out due to excellent reactions on the steering wheel and excellent clutch on the front axle, allowing the rotors with relative simplicity. In general, Michelin behavior in turns was the same impressive as their grip during acceleration and braking. Subjective assessments were put on the second place Bridgestone, also demonstrated excellent handling and informativeness, but the time of passing the circle dropped these tires on the last line, so the tires could not pass the route as quickly as the rest. The rescue of Michelin is less than two tenth seconds, the second in this test of the Pirelli steel, which has proven that they can be faster than it was possible to assume judging by subjective estimates. Pirelli do not have the same rapid reactions or stability in turns as michelin, but these tires provide just incredible clutch. At the end of the list, Continental turned out to be less informative and confident during the passage of slalom and high-speed plots, but their high level of clutch allowed them a little bit around Bridgestone.
On the wet surface, the rating was again headed by Michelin, which so confidently hold contact with the road, which even led to the fact that some pilots began to feel overheldly, because of which several drifts occurred - even despite such a high level of clutch. Continental also provide optimal grip on the wet surface, but they have too slow reactions to the driver's actions. Bridgestone clutch was weaker than that of Continental, but they pleased the same responsiveness and informativeness as on dry coverage. Pirelli is very balanced tires, well informing a clutch driver, but they do not sufficiently keep contact with the surface to catch up with the first three tires.
Fuel consumption
The test includes riding along a 10.5 km long route, including areas of the high-speed motorway (speed limit - 100 km / h), highway (90 km / h) and country road (65 km / h), as well as two signs of STOP and one Traffic light on each site. Pilots drove about 800 km in a few days. Since it was important to obtain fuel consumption, which will be ordinary drivers, Pilots observed speed limits and included cruise control everywhere where it was possible. Nic special techniques Fuel economy was not applied.
| Tires | l / 100km | consumption in liters for the year (24,000 km) | attitude to the most economical tires in the test |
| Bridgestone Potenza S-04 Pole Position | 10.6 | 2544 | -1.12% |
| Continental ExtremeContact DW. | 10.45 | 2508 | -- |
| Michelin Pilot Super Sport | 10.45 | 2508 | -- |
| Pirelli pzero. | 10.55 | 2532 | -0.75% |
It is important to understand that although more stable conditions have been created for greater accuracy, for indeed accurate definition The effects of tires on fuel consumption requires long-term tests, since changes in atmospheric pressure, temperature, etc. could influence the results of this test.
(The higher the indicator, the better)
