WINTER TYRES IN THIS YEAR’S BIG TEST

Prohibiting good tires - encouraging bad tires The city of Stockholm wants to prohibit studded tires this winter. At Aftonbladet Bil we do not want to do that. Not after studying this year's big test of winter tires. Really long braking distances with stud free tires may be good for the environment. But not for safety. And, making matters worse, perhaps not even for the environment. And if Stockholm politicians do not read our tire test at all, they are embarrassingly sloppy when reading the research results. Sure, studded tires tear up asphalt particles. But ALL tires are grinding down gravel and sand which snow in turn is spreading out to particles. And what is what? How much can be blamed on the studs? And how much of the particles are coming from the sand the city is spreading? Nobody knows.

In our tire tests we have many times shown how bad the stud free tires are on ice. As summer tires And we have also warned for the increasingly popular stud free high speed tires. I call them “Autobahn tires”, just because they are designed for high speeds on the Autobahn. Those tires are more similar to summer tires than the winter tires we are familiar with up here in the North. They have a rubber composition and a rigid structure that can withstand speeds over 200 km / h on hot, dry asphalt. They have a dense pattern that provides excellent stability at high speeds. The only difference with summer tires is that they have a certain preparation for coping with snow and slush. But they have virtually no grip on ice. That is why we have mass collisions with up to one hundred cars on the German Autobahn every winter. Ice is on the road and motorists have no chance to avoid the accident when driving fast, close to each other and lack grip on ice. This is the tires our politicians and authorities opens the door to when lobbying against studded tires. Who takes responsibility when the German accidents become common in Sweden? Claes Tingvall? Stockholm Environment Mayor Ulla Hamilton? Infrastructure Minister Åsa Torstensson?

Who takes responsibility when the German accidents become common in Sweden?

“Real men drove stud free” The debate regarding studded and stud free tires has been around for many years. From the beginning it was lead by “real men” who certainly not needed studs to drive during winter. They did not even need winter tires. You could just as well use decent summer tires. If you were a real man. Then came the Law on winter tires. Sure, hesitant politicians weakened the proposal quite much before it was voted on. There were exceptions for cars with foreign number plates, for trucks and buses - and for days with bare roads! But after all, the law was a good contribution to safer winter traffic. But the debate on studded tires never stopped. It was escalated by the big multinational tire companies that made everything to avoid development of studded tires just for the small Nordic markets. Authorities with financial responsibility for the asphalted roads and streets are more than willing to follow their arguments, and lean against the various researches on how particles affect health. 4

Right and wrong on asphalt Many believe that stud free tires are better than studded tires on asphalt. Right and wrong! Wrong - if we are talking about solving the stud free tires developed for our climate. Those tires are at least trying to have a grip on ice. For that reason they are extremely soft. It is soft rubber and tire lugs splitted into lots of “fins” in order to get a grip on ice.

Think about this before buying You find all information on the sides of the tires. 205/55 16 (which we tested) means that the width is 205 mm, the “profile”, i.e. the height from the asphalt to the edge of the rim is 55 percent of the width and 16 is the rim diameter - in inches. Also check the four date digits: 4908 means week 49 in 2008. Never buy (without knocking down the price) an old tire. The rubber gets harder when aging, furthermore the tires use an older technology, it is not the ‘most recent model”. Our prices are from online stores. Fitting of the tires is not included. Would you like to do business with the “rubber man”? Call a couple and check their prices! Half an hour on the phone can reduce the price with a few hundreds - per tire.

How we do the test In 1984 when I began to test tires with Test World we did it properly. Everything was done again and again. Always in blind tests, not to be influenced by brand names. Always on well prepared courses. We knew even back then that variations in the surface could affect the results more than the tires. The driver’s skill was another hidden factor. Even then, the tire industry respected our results and our methods were considered world leading. Our methods have improved even more with computers and satellite-based instruments. But we have not changed the most important. We still do all the tests again and again. With different drivers, different temperatures, on courses that have been prepared again since the last test round. We still use reference tires which are being tested again in each subtest in order to see how temperature affects the results.

“Tires from China are not even worth the money”

Tire manufacturers are doing everything they can to develop a good, stud free winter tire, but so far all attempts have failed. That is why we cannot do without studs. Studded tires are good on all surfaces. They have grip on snow and ice and has decent stability and braking distances on asphalt. Well, they wear on the roads. But that is a disadvantage we have to endure. For road safety. What about the air in the subway? Why do politicians in Stockholm want to prohibit studded tires? Is it really all about the particles and our health? Or pure economics, when streets and roads must be asphalted more often? If it comes to our health Stockholm ought to do something about the particle level in the subway immediately. It is much higher and more dangerous than the particles in Hornsgatan a dry spring day. Are there any more people than I who suspect that there is a dog buried in the alleged particle mountain? There are three types of winter tires: stud free tires - model Nordic and Central European - and studded tires. The Nordic stud free tires which are acclaimed in some tire tests and by the authorities and environmental

organizations are, in principle, bad on all surfaces except snow, where they may even be better than studded tires. The Central European tires are excellent alternatives to summer tires. They are bad on snow and slush and even bad on hard packed snow and ice. And the studded tires that work on all surfaces. But there are of course differences between good and bad within each group.

Enormous differences Expensive tires from major manufacturers are usually better than the cheap tires from China. It sounds obvious. “You get what you pay for”. But the difference is often so big that China-tires are not even worth the money. They are often so poor that they should not be allowed. But there are no rules about how tires should work. If the manufacturer says they are winter tires, they are recognized as winter tires.

Encouraging crappy tires Somewhere there must be quite distressing for the authorities: They allow any crap you want as long as it says “winter tires” on the side. And they want to stop people in buying the best available on the market and who are willing to pay extra to travel safely on winter roads. Good studded tires will be prohibited. Crap stud free tires from China will be allowed. Yes, even encouraged. It is quite frustrating. Both for us doing tests of the tires. And probably for those who are trying to produce the best and safest winter tires.

STUDDED TIRES

This is how we found the prices Importance of the result: The prices to the tires in the test are the lowest we found when we checked online tire stores. The prices are for 205/55 16 “. In a few cases where we did not find the tires on the net, we called dealers and got their prices. The price includes only the tires, not balancing and mounting. Note that tire prices vary dramatically, sometimes it can vary with up to 500 crowns from various stores - so you can save money if you put some time in searching.

This is a brand new tire with an old name, check that it is named “XIN2”“so you get the correct tires. Michelin wins when it comes to general performance, it is very good and safe on snow and ice, never gives you a surprise, and is almost not affected of roads having wheel tracks. However, the asphalt grip could be better.

An incredible winter tire! The new Hakka 7 is superior on ice, but it beats its competitors even on snow. The tire is ridiculously easy to drive and predictable even in the worst crisis. Its weakness is the grip on asphalt, but not even on bare roads the tire behaves badly.

Slightly behind the very best, but perhaps the choice for driving on asphalt. Conti produced its compromise for bare roads, which can be costly on winter roads. The tire has good steering qualities and good control when almost skidding. The tire is easy to drive on bare roads in all situations.

The Italians have improved their Carving tires and fixed an impressive grip on winter roads. The steering characteristics are precise which makes driving a pleasure. On asphalt you get average qualities, with sudden rear axle drops as sad surprises.

The Dutch Vredestein is another manufacturer that gives priority to safety qualities on bare roads at the expense of winter grip. On snow it works fine, but on ice it is a bit behind the best. On asphalt, it is very good even in tough evasion manoeuvres.

Now we skid from Korea to Taiwan with a bad grip on ice and snow, but most of all poor driving performance. It can suddenly lose the grip and without warning the front wheels may spin, and sometimes the rear wheels. You never know in advance. But on asphalt, it is really good. It feels wrong for the winter.

Now we skid on to Japan, though this time it is the bare road that creates the worst problem. Toyo is tricky with serious rear skids. It is not good on snow either. When steering or braking, you risk to skid. In fact, it is only on ice it works somewhat.

?+?+?+ German Conti is slowly dismantling the Gislaved legend who used to be “Best in Test “. Now the tires with Conti’s own brand is to be the best. Nordfrost is ok in all areas but not sticking out. The tire is quiet but rapid steering movements can create skids.

Michelin is by far the best of the stud free tires. This is the best tire on ice with good grip and silent qualities. But the best is the balance between the winter and bare road qualities, which represents a challenge for the stud free tires.

Nokian is second best in the group, but a far worse choice than Michelin. Safe on snow and ice and possible to maintain control even when skidding. But far to weak on bare roads. Braking grip is poor and it is difficult to control when driving fast. Lowest rolling resistance in the test!

?+?+ Here is a tire with good balance between its qualities: grip on snow; ice, slush and snow free. It means that the driver has pretty good control when not demanding too much from the tire. Unfortunately it is too little of everything.

Even, driving quality on asphalt.

Best stud free tire on snow with good grip and precise steering. On ice the grip is not as good as the best competitors. Good steering qualities, but pushed too much the result may be long and difficult skids. It is safe on slush but slow braking qualities on asphalt.

The old best seller Blizzak made the rear tires skid on asphalt and was really dangerous. The new tire built by Nokian has come to grips with the rear tires, but is still unstable on bare roads. On winter roads the tire is a medium performer in most things.

The American multinational giant is using its Japanese tires as the “Nordic alternative”. It is not a success. Just as Blizzak is qualities on asphalt miserable. It is difficult to drive and it has a bad grip. On snow and ice the grip is good, but it is difficult to control without skidding.

Yet another winter tire without any grip for winter surfaces. But it is marketed as” designed for the real winter “. Falken has no grip on ice and is even worse on snow. It loses grip everywhere and at all times. It is a dangerous, But: Approved by Vägverket (SRA)!

The German wins the group by a small margin, and epitomizes an Autobahndäck. It is best on snow and asphalt, but not that good on ice, which is hardly found in Central Europe. It is easy to drive with good steering qualities, it is stable and very quiet, but has high rolling resistance.

Dunlop demonstrates the dilemma of high speed winter tires - they are often very dangerous on snow and ice. The tire is nervous under all winter conditions, but worst on ice, and to gain control after skidding is virtually impossible. Good on wet asphalt, but lose grip here too.

With Pirelli WINTER 210 you do NOT want to end up on an icy spot, do not experience sudden frost, do not drive on black ice. But it is a winter tire and the type Vägverket (SRA) and many municipalities want you to change to. Without studs! However, on wet asphalt, it works really well. Congratulations, Tingvall!

Here is a high speed tire which oddly enough has ok grip on ice, but is falling through on any other road conditions. It is mediocre on snow, not good on slush, and strange enough - it’s not even really good on bare roads. Furthermore, it has an extremely slow roll.

A high speed tire with safe qualities on asphalt, the braking distance is the shortest in the entire test, and the rear axle never loses its grip, but it is diffuse and slow. Grip on ice is decent - good! But when it is snow or slush on the road, stay at home or find a parking spot!

Chinese Sonar surprised on ice with the best grip in the group. But on snow the grip is worse, and on asphalt and in slush, it is really bad. The problem is that the grip can disappear in a fraction of a second, especially on wet asphalt when you really want to feel safe.

“Chinese Plingplong has a surprisingly good grip in the longitudinal direction on both snow and ice. It drives and brakes well. But it loses grip with the rear wheels and it is just as hopeless to drive both on snow and ice. You may risk to collide with an oncoming car with your rear.
