GOOD GRIP
There is an abyss between the best and the worst studded tyres in our test. Low price may become costly. Brand tyres are however much closer to each other when talking about their grip feature on snow and ice. But winter tyres must be good on dry and wet surfaces as well. Text: Erik Rönnblom; Photos: Marko Mäkinen.
W
e have eight studded tyres in this year’s test. Last year’s winner Nokian Hakkapeliitta 5 has been replaced with number 7 in the test. The new version has a builtin dump in front of the actual stud body which makes the ice conditions on roads to mitigate. Buffing is reduced through less motion which in turn reduces the formation of particles. Nokian also has a really new stud which has six rims with two longer sides and reverse rolling direction in order to optimize grip while starting and braking. We put against Nokian several
well-known and best competitors, as well as, an actual outsider – Kingstar from China. Unfortunately, their tyre does not really appear to meet the requirements one should expect from a good winter tyre. The producers who for years have been developing, or at least testing, tyres in Nordic countries, have achieved a significant improvement in tyre performance, not only on ice, but also in wet conditions. That is why it is difficult to compete with the best producers of Nordic winter tyres. They have solid experience. It is difficult to succeed with a good compromise when the grip in difficult road conditions during win-

ter results in the fact that the tyre performs poorly when it is driven on a dry or a wet surface. This has always been a major problem, and 15 years ago when Vi Bilägare tested grip features in dry and wet road conditions. There are still differences to be found. Risk for reduced safety All the studded tyres have a common weakness which is a high noise level, especially on nonflat asphalt. But there is another unwanted feature. Studs tear roads and form small particles which are considered dangerous. Last year SMHI presented the research results which, not really
unexpectedly, showed that the number of particles was reduced if fewer people drive with studded tyres. The study covered the estimates for 20 towns. Three of them were under the environmentally qualified norm, 13 towns would not achieve the environmental target by 2010. But even if studded tyres are banned completely, five of them would not accomplish this target anyway. Last summer the government turned to the EU Commission in order to get permission for local bans on studded tyres. The discussion took place mainly in Stockholm where the results from Hornsgatan showed a too

Thus, to choose winter tyres means not only to talk about what is the best but also which of them we can afford or even allow to be used. Furthermore, the National Road Administration has learned to reach one of its goals – lower costs for road wearing. But there is a risk of safety becoming an exception. Many people choose studded tyres because they drive on other and more slippery road surfaces than those on Hornsgatan in Stock-
holm. Moreover, studs tear the ice which leads to better grip for friction tyres. If the drivers stop using the studded tyres, which seems to be the goal, friction tyres would polish roadways and make them more slippery. More salt? If we consider the solution for combating slipperiness with putting salt on roads, such an environmental eagerness produces further disservice. Putting salt on Swedish roads is another environmental problem. How many millions in damage are caused through road salt on cars and bridges? The polluting of
ground waters located close to big roads is even worse. These are familiar problems to the National Road Administration, and salting has also been reduced from an enormous 420 000 tons to 220 000 since the 1990’s. But five years ago the Geological Survey of Sweden, the SGU, mentioned in one of its reports that “It is important to reduce the usage of salt up to its minimum”. And at that time the estimation was calculated to 320 000 tons per year including municipality roads. So, what will the National Road Administration replace the studded tyres with? ✦

That is how the test was performed
★ The test for studded tyres was performed in Tammijärvi outside Ivalo on ice and snow, on the test courses outside Tampere when it was an issue about grip in slush, and on a dry and a wet road in Gislaved. The temperature during ice and snow-tests was mostly between minus four and minus eight degrees. All the tyres had a dimension of 205/55 R15. However, the indexes for weight and speed varied according to the producer. ★ The test for studded tyres was performed by our colleagues from the Finnish motor magazine Tuulilasi, and they used the VW Golf for the test. The team consisted of Oskari Pentti, Pasi Piironen, Juuso Kalloinen and Janne Vintturi. ★ The reference tyre was Gislaved Nord Frost 5. In every report for the test presented on pages 28-29, the results are partly in meters or in seconds, and partly in percentage comparison, when the reference tyre is always 100. The higher the value the better the result. A result can be rounded off which leads to the situation when differences are only revealed through the percentage comparison. ★ 205/55 R16 means that the tyre has a width of 205 mm. 55 indicates the height of the tyre in width percentage, i.e. almost 113 mm. R stands for radical, that the cord runs radically over the tyre. 16 is the tyre’s inner diameter expressed in inches which corresponds to the outer diameter of the rim. ★ 91 is the index for weight which means that the tyre can withstand a maximum of 615 kg. (94, a maximum of 670 kg). T is the speed in which the tyre is classified – 190 km/h (Q is for max 160 km/h and R is for max 170 km/h). Most of the other details about the tyres can also be obtained from the side of the tyre. ★ Pattern depth is measured using a special tool with hundredths of millimeter accuracy. ★ Hardness value is measured with a Shore measuring device used for testing how hard it is to push a small steel pin in the tread. The lower number the softer the tyre. ★ The number of studs is limited to the diameter of the tyre. A 16-inch tyre cannot have more than 130 studs. ★ Stud protrusion is measured firstly after driving which is performed under the same conditions and with reduced speed. Then the protrusion is measured after every test day. The protrusion can vary for different tyres. ★ Information about price is provided without expense for assembling and balancing and is taken from several different sources depending on the fact that rubber merchants had not yet fixed the autumn prices on the time of our price placement. The prices for Continental, Gislaved and Kingstar are taken from Svenska Gummihuset, Bridgestone – from Vianor, Michelin – from Alfvén & Ingvarsson, Nokian and Pirelli – from BytHjul.com, and Semperit – from OKQ8. The latest is the special price which is in force until 1/12. Price adjustments take place regularly in autumn. Prices from the Internet are not comparable with those of the rubber merchants. It is worth calling around and checking prices before purchasing. The prices we have provided were valid as of 25 August, 2009.

Bridgestone manages very well to pass in most of the test’s parts. It is easy to handle on ice and it rarely skids out under speeding up. Braking and gripping features are also very good. Snow conditions are also not a problem. Among the best, it does not get a grip when starting but is most effective when braking. For uphill in snow, the tyre has a slight tendency to skid but is easy to control. When driving fast, it can override and skid with a back trailer. Noranza 2 is safe in slush. Compared with the others, however, the tyre is the worst in braking on a wet road and for handling in wet conditions. Also, on a dry road Bridgestone is the worst of all the tested tyres, although it has a pass grade. Noranza is mainly a tyre which does a good job on ice and snow.
Continental does a good job on ice even though it is not the best. It is safe when performing consistent under steering, i.e. driving straight when it loses grip. It is sensitive to increased steering angle and has a sharp frontier for the grip feature. The tyre also manages very well in snow conditions. But the tendency for under steering requires more driving and while speeding up the tyres skid more than those of the best the competitors have. It works well in slush. This German tyre is among the best when it comes to wet and dry driving courses. It is actually relatively better in wet and dry conditions than on snow and ice. Altogether, WinterViking 2 is an excellent compromise. The tyre is safe in all conditions.
Gislaved in many aspect resembles ContiWinterViking but it does not brake as well on ice at 0°. It is neutral and handles well on ice, and does not require so much steering impact but can drive sideways while braking. It performs safely and under steers more often. Gislaved brakes on snow slightly worse than Continental but instead has a good side grip and is on top when speeding up. It also has a good grip and balance between traction and side grip in the uphill test. It performs very well in slush. It has very good driving features and ability to brake in wet conditions. It performs well in the test for braking on a dry road. NordFrost 5 is an excellent winter tyre which is, additionally, safe on wet and dry roads.

There is a terrifying difference between the premium producers’ studded tyres and the less-known Kingstar from China. Kingstar has fewer studs and the grip is much worse than that of the others’. Probably the rubber mixture in the tread is not suitable for low temperatures. Starting and braking features on ice are definitely unsatisfactory. But it is also hard to handle and the driver has to fight constantly to keep control of the car. Kingstar is better on snow but still definitely the worst in comparison with the others, constantly threatening to lose grip in front or behind the car. Kingstar, however, copes better than all of the other tyres in slush! It manages on wet roads well and brakes best on dry roads. It is a useless winter tyre.
Michelin has improved its position. X-Ice North on ice is in the same position with the icechampion HK PL7. X-Ice North is admittedly in second place while starting on ice and the first in the brake tests, but it is the best at 0 degrees, better when driving in circles and as good on icy roads. Drivers commend the tyre’s balance and its handling ability. Michelin is very good on snow. It is assessed as calm, well-balanced and safe to drive with. It manages quite well in slush. The ability to brake in wet conditions is assessed as acceptable. The sense of driving however is very good. It under steers without skidding. The ability to brake on dry roads is no more than acceptable. X-Ice North, as its name suggests, is mainly a tyre for real winter conditions with an acceptable performance in wet and dry conditions.
Nokian starts at its fastest on ice and brakes at its best at -7° and almost its best at 0 degrees. On the ice course the tyre is in time a little after Pirelli and Bridgestone. The drivers’ assessment is that the tyre is very easy to drive with. Its ability to start and brake on snow is on the same level as the best competitors. Nokian is the fastest in the test for driving uphill, and it gets the highest grade for its performance on snow even if it goes with a slight but controllable skid while accelerating. Nokian is the best of the winter tyres in slush (not taking into account Kingstar). The grip in wet conditions is much better than before, and the ability to brake in wet conditions is currently good. It is very even at the top, but Nokian is very hard to compete with when talking about its performance on ice and slush. The steering response is excellent and the grip on dry and wet roads has been improved.
Pirelli manages the tests for ice-driving really well and is commended for its features. It is weakly under steered, and when it skids the tyre does it softly and with control. But we also note a slightly higher degree of stud protrusion. Carving Edge starts fastest on snow and brakes well. It is on the third place when driving up hills and is assessed as the outstanding to drive with and neutral with soft skidding when speeding up. Pirelli manages worst in slush. The grip in wet conditions is good and it brakes as effectively on wet and dry asphalt. Carving Edge performs well on both ice and snow but it is worse in slush. The end result is a shared second place with Gislaved.
Can budget tyres compete against the premium class tyres? Semperit places itself, with some exceptions, always after the well-known brand tyres, however the results are completely acceptable. It has a slightly worse grip on ice but the features are consistent, and it is assessed as easy to handle. The grip on snow while starting is very good and the ability to brake is at the same level with those of the almost best tyres. However, the tyre skids more than those of the best ones on snow. Semperit manages to drive on a wet road very well, and the same is true when to talk about its handling while braking. Its ability to brake on a dry road is also really good. The tyre has acceptable features when driving on ice and snow. Taken together, it is a very good winter tyre which is worth the money.

Semperit needs three additional meters in such low speed levels than the best tyre. Kingstar seems to have runner instead of stud. When braking from 90 km/h on ice, the difference increases to around 70 m longer braking distance for the worst tyres in comparison with the best ones! %

★ When driving on a wet road, the difference between the best and the worst is just several seconds. However, the experience behind the steering wheel is much more varied. The differences here are mostly about how much the tyres under steer or tend to skid. Gislaved, Continental and Nokian keep on the track the best and are the easiest to drive with. With Kingstar drivers feel most nervous, anticipating a sudden loss of control.

★ The biggest weakness of the studded tyres for a person is the noise level. Unfortunately the cars have become worse in this aspect. Studded tyres are already considered as excessive at quite a low speed. They are not going to be really comfortable in this aspect. On a smooth road at 50 km/h a studded tyre makes the same noise as a non-studded one at 90 km/h.

★ Kingstar is the best here. It is the only tyre which is slightly better than the average result at 32,8 m from 80 km/h to an almost stationary position. There is also a small difference between the studded tyres’ ability to stop the carriage. The braking distance is acceptable for all.
★ It is not only about speed, the tyre should make driving easier. For a tyre with sharp frontiers between grip and non-grip features a journey becomes unpleasant. As with Kingstar, there is a shift between the tendency to drive straight and to skid with a back trailer.

★ 80-5 km/h. Studded tyres have always slightly more stable tread blocks. It leads to better braking features because there is a risk of soft parts folding down and sliding. The differences in results between the studded tyres are also relatively small. The difference is more considerable between friction tyres. The tyres from the Continental Group (which also produces Gislaved and Semperit) performed the best in this test.
