Over 100 years with Nokian tyres

Over one hundred years of professional skill, inventiveness and will – the roots of the business extend all the way back to 1898, when Suomen Gummitehdas Osakeyhtiö was founded. Nokia rose up on the map in 1904 when technical manager Antti Antero and Dr. Birger Pentz, who had been looking for a site for a factory, became enchanted with the verdant surroundings along the river. The benefits of the factory relocation from Helsinki to Nokia emerged quickly when production increased and the final accounts showed black ink.

The first tyres

With the increase in transport traffic, Suomen Gummitehdas Osakeyhtiö began the manufacture of bicycle tyres in 1925. The resourcefulness and urge for development of our personnel already find their roots in the early days of the establishment of the firm. In 1912, long before the production of the first Finnish tyre (in Norwegian: dekk) for car vehicles, Managing Director Eduard Polon and Antti Antero had given attention to the new winds blowing in the world. They were fascinated by the manufacture of car tyres as a new field of production but, being wise men, they decided they would first acquire the know-how to do it from America, where motor vehicle reserves had already exceeded one million. Finland’s vehicle reserves were much more modest and did not reach above one thousand cars till ten years later.

From the bold ideas of its origins, two decades rolled by before the first Finnish car tyre was born, in 1932. The structure of this oven-fresh tyre was studied inside out, after which painstaking development work was initiated. General tyre manufacture began about nine months later, in April 1933. The world’s first winter tyre – kelirengas – was developed in 1934 particularly for Finland’s conditions: its road network, variable terrain and winter use. The first kelirengas tyre patterned and configured for winter surfaces was intended for trucks.

Hakkapeliitta – a winner over snowy roads

On the basis of the kelirengas winter tyre, the first Hakkapeliitta tyre was developed in 1936, which was later named lumi-Hakkapeliitta (lumi = snow). There was a stepped, relatively scattered transverse pattern in the surface model of this winner over snowy roads, equipped with ‘suction cups’. The surface pattern of our lumi-Hakkapeliitta remained unchanged right up till the 1950’s.

The story of Hakkapeliitta winter tyres has continued unabated for 75 years. The core task of Nokian product development has been maintained from decade to decade without change: the world’s best winter tyres which are well-suited in their characteristics to the demanding and varying driving conditions of the north.

Dangers of Aquaplaning and slush planing

When driving on a dry road in the summertime, drivers hardly have to think about their tyres. When a thunderstorm breaks or a persistent summer rain fills the grooves in the road or a slush-weather occurs in between harder winter conditions, it is quite a different ballgame. The danger of aquaplaning and slush planning can be felt in the steering: it is difficult to control the car, especially if the tyres are in poor condition or worn out. The best way to prevent aquaplaning and slush planning is to use new tyres. Even new tyres do not completely eliminate the risk of aquaplaning or slush planing, but it is possible to control the car as long as you adjust the driving speed to the conditions.

From the viewpoint of traffic safety, it is important to have both winter as summer tyres with the proper groove depth and properties to suit the weather conditions. When there is excess water or slush on the road and the driving speed exceeds a certain limit, the tread pattern of the tyre no longer pushes aside the water or slush from underneath the tyre. The feel between the tyre and the road will be lost, and so will the grip.

When there is less than four millimeters of tread on the tyres (in Norwegian: dekk), the tyres' wet grip and aquaplaning as well as slush planing properties essentially deteriorate; the risk of aquaplaning and slush planing, in particular, greatly increases. Furthermore, the breaking distance is longer and the car will skid easier. Tests conducted by Nokian Tyres show that with a worn-out tyre (tread less than 1.6 millimeters, approximately 5 millimeters of water on the road), aquaplaning or slush planning will occur when driving in a curve at the speed of 80 km/h, whereas the aquaplaning and slush planning speed for new tyres is 95 km/h.

When the driving speed increases and the tyres wear out, the contact area between the tyre and the road is dramatically reduced. The contact area of a vehicle with worn-out tyres, 1.6 millimeters, is only 16% when compared to a stationary vehicle.

Nokian Tyres has unique facilities for carrying out slush planing tests

"Nokian Tyres’ Matti Morri Technical Customer Service Manager on questions regarding hydroplaning and slush planing"

What benefits does this bring?

"As far as I know, no other tyre (in Swedish: däck) manufacturer has a place for testing slush planing in a controlled testing environment in the way Nokian has. Every winter, we pile a lot of snow on our test track, and when the spring sunshine starts to melt the snow into slush, we carry out extensive testing. Although hydroplaning is dangerous, slush planing is even more dangerous. The combination of melting snow, a layer of water on the road surface, and possibly ice can make the situation difficult, even for an experienced driver. Even though we are the pioneers of the industry, even we discover something new every spring."

Is the superior quality of new tyres accentuated in difficult conditions?

"Nokian customers who have driven on our test track have been amazed by the difference between tyres with a tread depth of 4 millimeter and brand new tyres. Unfortunately, few people have the opportunity to experience themselves under safe conditions how quickly water or slush on the road can turn a driver into a passenger."

What can you do if hydroplaning or slush planing occurs?

"Factors that affect the occurrence of hydroplaning that can be influenced by the driver are tyre tread depth, tyre pressure and speed. If, in spite of everything, planing occurs, the first thing to do is to reduce speed and try to re-establish a feel for the road. Only then will it be possible to steer. I cannot understand why people insist on driving in the ruts in the road even when it’s raining, as that is the first place where water will start to collect."

10 Milestones of Ivalo Proving Ground

Nokian Tyres' 700-hectare proving ground in Ivalo, Finland, is in use from November to May. With state-of-the-art equipment, the different tests and the expert staff make sure that all the extreme situations in winter driving are thoroughly studied.

1. Grip on Ice

Tammijärvi Lake is the largest lake at the Ivalo proving ground. Three straight test tracks measuring one kilometer each are set upon its icy surface each winter in order to measure tyres’ grip during braking and acceleration. Three 20 meters x 1,000 meters ice straights

2. Grip on Snow

The friction values of a tyre’s lateral and longitudinal grip are measured using equipment installed in the test vehicle. Tests are conducted on two straights of different lengths. The surface on these tracks is made up of hard-packed snow. Test tracks: 20 meters x 1,000 meters and 25 meters x 500 meters.

3. Hill Test

The hill test is used to measure and evaluate how a tyre (in Swedish: däck) climbs up a steep slope. Three routes with different profiles and steepness and a different number of curves lead up to the hill. Test results are obtained from the test driver's comments and objective measurements - maximum 20% incline - three routes: 1,000 meters, 900 meters and 500 meters.

4. Handling on Ice

Conducted on an icy surface, this handling test measures a tyre’s maximum grip in curves with different radiuses and on a long straightaway. Measurement results and the test driver's views are used in the evaluation. Two ice-covered tracks: 800 meters and 1,000 meters.

5. Handling on a Snowy Track

In this handling test, an experienced test driver compares the tyres’ behavior on a snowy track, i.e. on a hard-packed snow surface. The route measuring just over 12 kilometers simulates ordinary road conditions with its slopes and curves.- a winding road with slopes and curves, about 12 kilometers long hard-packed snow surface

6. Handling on a Snowy Track II

The second track intended for evaluating tyres’ behavior in snow is about one kilometer long. In testing terms, this is a so-called index track where tyres’ basic properties can be defined. The demanding route features a large number of curves with different radiuses. Test drivers find out the difference between various tyres by driving at the extreme limits of the tyres’ grip and at extremely high speeds. Measured driving times and the test drivers' subjective assessments complement each other.

7. Lateral Grip and Longitudinal Stability on Ice

A tyre’s lateral grip and longitudinal stability are determined by evaluating its behavior on ice. Lateral grip is tested on an icy circle track. Lap times are recorded in the circle track test, and otherwise comparisons are based on subjective views of the tyre’s handling. When carrying out tests on ice, testers aim to keep conditions as constant as possible by roughening the track's surface with a specially designed roughener. The objective is to keep the ice evenly slippery. Circle diameter 300 meters – handling track 2,300 meters.

8. Maintenance Area: Office and Garages

The Ivalo proving ground has a maintenance building, housing the office premises and a meeting room. During the busiest periods, testing is carried out on an extremely tight schedule, with all available time utilized as efficiently as possible. The garages are used to store and service test cars and equipment used for repairing the test tracks, and to mount and change tyres.

9. Handling on Ice II

This handling test which is conducted on an icy surface measures a tyre’s maximum grip in curves with different radiuses and on a long straightaway. Tyes are evaluated based on measurements and test drivers' views. Ice-covered track: 900 meters.

Over 75 years of Nokian tyres

The Nokia rubber factory launched passenger car tyre production in 1932 when the compressors and curing presses required for tyre manufacture were ordered. The first Nokian tyres featured four layers of fabric and a very flat surface, as if a board had been slammed on the tyre (in Swedish: däck).

The world’s first winter tyre in 1934

In the very early stages of tyre manufacture, Nokian engineers were quick to understand the need for a tyre type that was specifically suited to the Nordic conditions. As a result, the first tread-patterned tyre designed for winter use in trucks and heavy vehicles, or “weather tyre” as it was called, was manufactured.

The first Hakkapeliitta tyre manufactured in 1936

The first winter tyre paved the way for the first Hakkapeliitta winter tyre designed for passenger cars, later named Snow Hakkapeliitta. The tyre tread showed a stepped, relatively sparse transverse pattern equipped with so-called suction pads. This tread pattern remained unchanged until the 1950’s. Before the Winter War, Nokian manufactured 20 000 Hakkapeliitta tyres in six different sizes.

Worldwide introduction in Monte Carlo

The history of Nokian Hakkapeliitta winter tyres is colourful and prestigious. Manufactured since 1936, Hakkapeliitta tyres achieved worldwide fame in the legendary Monte Carlo rallies in the 1950’s and 1960’s. Cars equipped with studded Kometa Hakkapeliitta tyres were superior on snowy and icy mountain roads. Finnish drivers continued to do well in rallies, giving rise to the notion of "Flying Finns". Hakkapeliitta tyres proved their unique features and were soon coveted by competitors from many different countries.

World record in ice driving

Today's Hakkapeliitta tyres also perform excellently in fast-paced challenges such as the Monte Carlo rallies. The new world record for fastest car on ice was set by Nokian Tyres' Finnish test driver Janne Laitinen who drove 331,610 km/h (206,05 mph) on the Gulf of Bothnia, in Oulu, Finland. The record was broken on March 6th 2011 on a 14-kilometer ice track in freezing conditions. The world's leading winter tyre manufacturer equipped the record-breaking car with Nokian Hakkapeliitta 7 studded tyres (255/35R20 97 T XL).

75 years of safety

The R&D principle has remained more or less the same for over 75 years: the demanding objective is to develop tyres for people driving in Nordic conditions who value safety and who expect reliable tyre performance in any situation. The latest additions to the Nokian Hakkapeliitta family are the studded Nokian Hakkapeliitta 7, the Nokian Hakkapeliitta 7 SUV and the studless Nokian Hakkapeliitta R. All tyres have achieved several wins in tests conducted by both Finnish and international magazines. The tyres include many innovations that improve the grip in demanding weather conditions, reduce the rolling resistance and consequently fuel consumption and carbon dioxide emissions.

Nokian Tyres Fastest on Ice

The new world record for fastest car on ice was set by Nokian Tyres' Finnish test driver Janne Laitinen who drove 331,610 km/h (206,05 mph) on the Gulf of Bothnia in Oulu, Finland. The record was broken on March 6th on a 14-kilometer ice track in freezing conditions. The world's leading winter tyre manufacturer equipped the record-breaking car with Nokian Hakkapeliitta 7 studded tyres (255/35R20 97 T XL).

Extreme speeds emphasize the role of top-quality tyres; they are the vehicle’s only contact point with the driving surface. When driving at exceptionally high speeds on slippery ice, the tyres must provide maximal grip, excellent structural durability and handling properties that are in line with the car's high power.

The acceleration formula is demanding. When a car moves at a speed of 331 km/h, the car covers over 92 meters in one second. The tyres are under immense pressure at these high speeds, and their diameter can increase by 15–20 mm.

As the air resistance increases, more traction is needed in order to pick up speed. Testing at high speeds in demanding conditions forms an important part of the Nokian winter tyre (in Finnish: talvirengas) development. Testing the boundaries can teach new things, which can then be reflected in all of the products explains Matti Morri from the Nokian Tyres' Technical Customer Service Manager.

The Guinness World Records organization outlines detailed rules for ice driving world records. The time for the one-kilometer distance is taken for driving in both directions of the track, and the world record time is the average of these two results. The vehicle takes a flying start. There is a total of one hour to complete the record attempt. The ice has to be natural and it may not be roughed up or treated with any chemicals. The tyres must be commercially available and approved for road traffic in the country in which the record attempt takes place.

Nokian winter tyre master of extreme conditions

Nokian Tyres developed the world’s first winter tyre for raw, subzero conditions back in 1934. Two years later, it introduced the Hakkapeliitta, designed for northern winters and today one of the world’s best-known winter tyre brands. The world’s northernmost tyre manufacturer tests and develops new additions, customized for different uses, for its winter tyre family at its own test facilities in Ivalo, 300 kilometers north of the Arctic Circle.

Nokian Tyres is the only tyre manufacturer in the world that focuses on products and services that facilitate safe transportation in Nordic conditions. The company's innovative passenger car, van and heavy-duty machinery tyres are mainly marketed in areas that have snow, forest and changing seasons that make driving conditions demanding. Nokian Tyres owns the Vianor tyre chain that comprises more than 770 stores in 20 countries. The company's net sales for 2010 totalled approximately EUR 1,058 million, and it had 3,500 employees.

When is it time to replace worn tyres with new ones?

As a general rule it could be said that when you're preparing for the winter in the fall, the tread should have at least 2/3 of the groove depth left. This means that the tyre still has a sufficient tread and edges to provide a good grip.

The Vianor Industrial Grows

The growth of service requirements and high demands of technology within the field of heavy construction machine tyres (in Finnish: renkaat) has put the unique concept of Vianor on the map for reaching over the standards of customer service. In Finland, Sweden, Norway and Ukraine, the concept of Vianor Industrial is already close to 30 outlets.

Particularly in Sweden the Vianor Industrial concept has grown rapidly. There are already 12 fully specialized Vianor outlets and four new Vianor Industrial establishments will open in early 2012.

  • The technical training of the staff in these four service stations has been largely completed. The tyre repairing and installation of equipment inventory, and investments are also currently underway, says Vianor’s product manager of tyres for industrial vehicles, Leif Karlsson. The Vianor Industrial concept will continue to grow elsewhere, because Ukraine is currently negotiating for new outlets. In addition, the concept is being extended in the future, at least in Kazakhstan, and Russia.

The tyre chain Vianor and Nokian Heavy Tyres jointly developed the concept of Vianor Industrial for a professional service of heavy duty-tyres. The concept is used in the vertical plane for entrepreneurs and contractors to provide professional solutions utilizing the latest innovations and business models.

The strength of the concept is that Vianor improved the ability to be close to customers and understanding the different tyres with anticipation of the needs and to develop new solutions to problems within both the production as on the service side. Cooperation with Nokian Heavy Tyres enables the flow of information and development in an unbroken chain of products between the manufacturer, distributor and end-user, says Vianor’s marketing manager of heavy tyres, Juha Lehtinen.

Trained and expert dealers with special skills are also available to customers in other Vianor outlets, which are constantly consulted and further trained when needed in order to achieve the best possible solutions for the end-user. The Vianor Industrial concept is growing in the future, together with the involved retail outlets.

At present the retail outlets in Finland operating within the Vianor Industrial concept are located in Hyvinkää, Tampere and Ylivieska.

Prepare for winter with Nokian

Variable and demanding winter conditions are becoming more and more common in European countries, creating surprising situations all over the continent. You should be prepared for the winter, no matter where in Europe you are driving. By being prepared you can ensure traffic safety and flow, also in the wintertime.

Wintery and variable conditions require a lot from the Nokian winter tyres (in Norwegian: vinterdekk). The regulations regarding heavy vehicles’ winter tyres vary greatly from one European country to another. You are always required to follow the statutory regulations of each country, but you should also keep in mind that they are only the minimum requirements. You should always select the right Nokian tyres according to the conditions and intended usage, even if there are no regulations.

Nokian Winter tyres with an excellent grip in winter conditions are absolutely necessary to ensure traffic flow and safety as well as the efficiency of transportation. Therefore, you should pay attention to the properties of the tyre when selecting winter tyres to ensure the maximal safety and efficiency on wintery roads.

The Nokian winter grip of a tyre (in Norwegian: dekk) is created by the tread pattern and rubber compound. The openness of the pattern affects how well the tyre cleans itself of the snow. A high level of siping creates extra edges that grip the road and increase traction. The rubber compound especially affects the grip on icy surfaces. As the tyre wears down, both the sipes and the openness of the pattern (land/sea ratio) reduce, which causes the edges to disappear and the cleaning ability of the tyre to weaken. In the course of time, the tread rubber compound becomes harder, which also reduces the tyre's grip.

FAQ – Teppo Siltanen, the Product Development Manager from Nokian Tyres answers

How should I prepare for the winter?

You should of course be prepared, so that the winter conditions don't catch you off-guard. What this means is that you should replace worn tyres with new ones early enough.

Which properties should be emphasized when selecting Nokian winter tyres and why?

The Nokian winter tyres have to be selected according to the usage. If you only drive on main roads, it's usually sufficient to use so-called All-Season tyres. But if you often drive on smaller roads, it's recommended to use actual winter tyres. It's also important to check that all tyres have the M+S (mud and snow) marking.

What should be taken into consideration when selecting Nokian, steer axle tyres, drive axles tyres or trailer tyres?

In winter conditions, the tyres should have tread models with an open pattern. Free-rolling tyres need to have sufficiently wide grooves and drive axle tyres a clear block pattern. Sipes also increase the grip.

You should also pay attention to your trailer’s tyres. The most important axles in regard to the behavior of a trailer are the last axle and the dolly's second axle. The tyres used on these axles affect the trailer's stability the most, especially on slippery roads.

Does the M+S marking (mud and snow) guarantee that the tyre is safe in winter conditions?

The M+S marking does not guarantee that the tyre is safe on wintery roads because there is no rule defining the M+S marking. Reliable tyre manufacturers, however, are very strict with the marking. Nokian Tyres' M+S marking is based on tested data, which means that the tyre's grip has to be better than that of similar tyres in the market on average.

When is it time to replace worn tyres with new ones?

As a general rule it could be said that when you're preparing for the winter in the fall, the tread should have at least 2/3 of the groove depth left. This means that the tyre still has a sufficient tread and edges to provide a good grip.

More test results for Nokian winter tyres

Tailored for the Northern winter and climate, the Nokian Hakkapeliitta winter tyres (in Norwegian: vinterdekk) have been dominating the winter tyre tests in different car magazines for years, and year 2011 is no exception. The winter tyre tests show good results in performance and with distinction again this autumn. Nokian Hakkapeliitta is designed for the Northern roads, but test results show excellent performance for the Central European roads as well.

The new Nokian WR D3 was a leader in the winter tyre test made by the German Sports Auto magazine (11/2011). The German magazines praised the Nokian WR D3's new features in winter snow (99 points out of 100 possible), but also in dry conditions (68 points possible 70). "Nokia is clearly above their competitors when it comes to the winter climate. You can also rely on Nokian on the dry weather, "Sports Auto writes. Six non-studded winter tyres with size range of 225/45 with R17 were tested.

"Highly recommended," said renowned German car magazines Auto, Motor und Sport (21/2011) and Auto Zeitung (20/2011) in their winter tyre tests with Nokian WR D3 tyres. Both magazines praise the tyre (In Norwegian: dekk) for maintaining the performance on snow and dry asphalt. The world's northernmost tyre manufacturer's new product reached the best results in the German TV program named Auto Mobil. The new Nokian winter tyre WR D3 was also victorious in the Finnish magazine Tekniikan Maailma.

Tekniikan Maailma (19/2011) also tested friction tyres designed for the Central European winters in high-speed intentions (e.g. 210 km / h and 240 km / h). One was above all others: Nokian WR D3. Tekniikan Maailma praised particularly the new product for maintaining drive-ability and winter conditions as well as low rolling resistance.

According to Tekniikan Maailma, Nokian is the world leader of friction tyres in high-speed conditions when the road is slippery in winter. This is due to its safe and steady grip and reasonably good performance also on icy roads which is always a great challenge for friction tyres.

In the Swedish Aftonbladet’'s BIL (8 / 2011) test, Nokian WR D3 was the best Central European friction tyre. "The tyre is by far the best Central European non-studded winter tyre. A Central European tyre with a good grip on ice and snow, and low rolling resistance, they wrote”. The magazine tested 10 Central European non-studded winter tyres in size category 205/55 R16.

Nokian winter tyre WR G2 SUV

The new Nokian WR G2 SUV was developed with the needs of European SUV drivers in mind. When designing this high-performance winter tyre (in Swedish: vinterdäck), Nokian Tyres’ winter experts focused on consumer wishes. Special attention was paid to the tyres’ handling properties, particularly at high speeds and on all kinds of road surfaces. The Nokian WR G2 SUV is excellent for driving on snowy roads and bare asphalt at high speeds. The tyre’s excellent slush properties have not been achieved by sacrificing other basic features of a good, balanced winter tyre. The Nokian WR G2 SUV is not afraid of water: it holds its grip, remains stable and stops precisely on wet and watery surfaces. Thanks to the splined centre rib, the Nokian WR G2 SUV rolls sensitively and easily. Lightly rolling tyres consume less fuel, which, consequently, reduces CO2 emissions.

A stable tyre with a good grip on snowy, wet and dry surfaces

The slush grip of the new product is based on new technical ideas and innovations: the slush edge, an asymmetrical tread design and polished grooves. The new innovation, the power on/off stabilizer, enhances the safety and driving properties of the tyre in all situations, especially during rapid acceleration. The rubber compound of the Nokian WR G2 SUV combines silica and plant-based canola oil, which is derived from a natural raw material. This compound improves the tyre’s wet properties and handling properties. The natural oil provides improved resistance to tear and better grip in cool weather.

For a unique winter grip and soft road contact, the tyres (in Finnish: renkaat) are equipped with the Air Claw Technology – a flawless combination of an entirely new stud solution and the droplet-shaped air shock absorbers in the front edge of the tread blocks.

Slush edges maximise lateral grip

For heavy, high-performance SUVs, balanced grip characteristics and the ability to control them are vital. Drivers who love to drive an SUV especially want reliable lateral grip to ensure good steering and stability of the high vehicle in high speed and in extreme conditions. To further improve the excellent lateral grip of the Nokian Hakkapeliitta SUV 7, the shoulders of the tyre are equipped with staggered slush edges customized for SUV use. The new SUV Hakkapeliitta has the ability to optimally utilize the new driving stability management systems and thereby to deliver added safety and better performance in demanding circumstances

Driving comfort with balance and precision

The sporty, high-grip tyre carries the heavy tyre load with excellent control, stability and reliability on an icy and wet road. The tyre also delivers superior performance on snow and on clean roads. In addition to convincing grip in extreme conditions, this SUV tyre provides a precise, logical and balanced driving experience. The aggressive tread pattern features a dense, sharp-edged zig-zag siping to provide additional grip. Thanks to the geometric tread design, the tyre will not get clogged up with snow or slush; instead, it cleans easily and runs effortlessly in deep snow and slush on challenging forest roads.

Side impact protection gives added durability

In SUV use, the side walls of the tyre must also be able to withstand cuts and punctures. The multi-purpose Nokian Hakkapeliitta 7 SUV comes with side impact protection for better durability.

The tyre tread is made from a compound of natural rubber, silica and canola oil, which improves tear resistance and grip on ice. In addition, the tyre can easily withstand punctures from sharp-edged stones.

Safety with the tyre condition indicator

Tread indicators show the tyre condition, which increases driving comfort and safety. Developed and patented by Nokian Tyres, the Driving Safety Indicator (DSI) indicates in numbers how many millimeters of tread remain in the main grooves of the tyre. Similarly, the snowflake symbol is a winter safety indicator. It remains visible until the groove depth is four millimeters. For safe winter driving, the required groove depth is at least 4 to 5 millimeters. The Nokian Hakkapeliitta 7 SUV will first be available in a range of sizes covering 21 items from 16” to 21” tyres.

Nokian Hakkapeliitta winter tyre 5 SUV

The Nokian Hakkapeliitta product family will expand with a potent newcomer when Nokian Tyres introduces its new Nokian Hakkapeliitta Sport Utility 5 designed for SUVs. The Nokian Hakkapeliitta Sport Utility 5 offers the same ingenious technical solutions found in the new Nokian Hakkapeliitta 5 for passenger cars. In addition to their appearance, several common innovations identify the tyres as twins.

Good grip, sturdiness and durability

High-performance tyres (in Finnish: renkaat) for heavy vehicles must offer excellent grip. Well-balanced grip properties are essential when designing tyres for SUVs. Maximizing the lateral grip is of particular importance in order to ensure that the vehicle can be controlled under extreme conditions. The bear claw and upgraded square stud also enhance the grip of the new SUV tyre.

Polished main grooves

The handsome and massive SUV tyre features polished main grooves. Snow and slush come easily off the tyre along the smooth and shiny grooves. Thanks to the tread pattern, the tyre cleans easily and runs effortlessly in deep snow and slush on challenging forest and cabin roads.

Safety from alerts, tips and indicators

Signs and alerts make winter conditions easier for SUV drivers and increase safety. Drivers can affect the resistance of studs and how they fall into place by running in brand new tyres. Calm and careful driving is recommended during the first 500 kilometers: avoid hard breaking and acceleration, as well as abrupt controllability. All studs are encircled by a run-in indicator that fades at the end of the run-in.
